2.2. SAFET Y INSTRUCTIONS.

•

It is required to check the installation information

the nameplate.

• Please remember that the UPS is an electrical energy generator, so the end-user must take all the needed cautions against direct and indirect contact.

Its power supply relies on the batteries, a n d AC mains, which are included or excluded in the case or cabinet of the electronic parts of the equipment depending on the model and/ or extended autonomies.

When the

equipment

is ON, and the

batteries

are

connected

to the equipment and its protections, if any, are turned “On,” the fact that the UPS is connected or not connected to mains is irrelevant, and neither is the protections of mains. The outlets or output terminals will supply voltage when there is energy in the battery set.

• Compliance as regards to “Safety instructions“ is

mandatory, being the user the legal responsible

regarding

to its

observance and application. Read

them

carefully and follow the stated steps in the established order, keep them for future consultations that may arise.

• If the instructions are not in total or partial understood and in special those ones referred to safety, do not

carry

on with the installation or

commissioning

tasks,

because

there could be a at a risk of your or other persons’ safety, being able to make serious injuries even the death, also it can cause damages to the equipment and/or loads and installation.

• The local electrical regulations and the dif ferent restrictions of the client’s site can invalidate some

recommendations included in the manuals. When discrepancies exist, the user has to comply with the local regulations.

• This equipment must be installed by qualified

personnel and for personnel with no specific training, just act with the help of this manual.

A person is defined as qualified, if he has experience in assembling, commissioning and perfect control operating of the equipment, if (s)he has the requirements to do the job and if (s)he has read and understand all the things described in this manual, in particular the safety indications. Such preparation is considered valid if it is certified by our (S.T.S.) only.

• Warning labels have to be placed in all primary switches, installed in

areas far away from the equipment, in order to warn the electrical maintenance personnel of the presence of a UPS in the circuit.

The label shall contain the following text or an equivalent one:

Before operating in the circuit.

Isolate the Uninterruptible Power Supply (UPS).

Check the voltage of all terminals, including the

earth

main protective earth.

Risk of UPS backfeed voltage.

• To manipulate the connected terminals of the

equipment, which has been already connected to mains,

wait for five minutes after its complete isolation, before taking any action in it.

2.2.1. Points for Attention

• The UPS is supplied in complete package from factory in the

best way for its transport and shipment till you receive is. It is recommended to remain it packaged until it arrives to its final location.

• When serious damages are observed in the package, or its level

of damages can be sensed in the contents and/or the shock indicator is in RED, handle the product according to the instructions stated in the own label of transport control.

Keep the affected equipment isolated from other received equipment, and wait the further inspection by qualified staff.

In case it has to be returned to the factory or your distributor but the same package is in poor conditions, contact with the appropriate person in order to agree the way and conditions for its return.

• Respect the unpacking instructions, as well as the established

mode to remove the equipment from the pallet.

These operations require the manpower of at least two persons.

• The equipment has to be always in vertical position.

When moving the equipment, consider the slope of the

ground or surface and the risk of tipping.

• Be careful not to lif t heavy loads without other people’s help.

Please refer to the following recommendations:

, < 18 kg. , 18 - 32 kg. , 32 - 55 kg.

, > 55 kg.

• To avoid accidentally dropping equipment or any

damaged enclosure, do not start it up under any concept. This kind of fault can cause fire or electrical discharge. Contact with our (S.T.S.).

• Some models include casters to move it till its location. They

are not designed for long distances or constant movements.

The equipment shall be guided by two persons as minimum, which will be placed on either side and oriented to the walking direction.

• UPSs are electronic equipment. Avoid jolting or bouncing like

those produced by moving the equipment over an uneven or wavy surface.

• When moving an equipment from a cold to a warm environment

and vice versa, condensation (small water drops) might occur on the external and internal surfaces. Before installing a moving equipment from another place or even package, the equipment should be placed in the new location for a minimum of two hours before making any action, with the purpose of adapting it to the new environmental conditions and avoid possible condensations.

The UPS has to be completely dry before starting any

installation task.

• Do not store, install or expose the equipment in corrosive, wets, warm, dusty environments or with conductive parts and never outdoors.

The best location for installation should be cool, dry and far from heat sources and easy to access. If possible, place it in an environment with temperature control.

• Avoid locating, installing or storing the equipment in places with direct sunlight or high temperatures. Batteries might damage and/or shorten its lifetime.

In the exceptional and long exposure of intense heat, batteries can cause filtrations, overheating or explosions, which can cause fires, burn or other injuries. High temperatures can also make deformation in the plastic enclosure.

• Do not obstruct the cooling grids by ins e r ting an y objects through themselves or other orifices.

• Locate the equipment to the power supply outlet and supplied loads as close as possible, leaving an easy access in case of an urgent disconnection.

• All models with casters have four leveling feet at each corner of the base, with the purpose of locking and level the unit.

Loosen them until they can be lifted from the ground.

With the help of a spanner, act on each one and loosen them half round more against the ground.

For slightly uneven grounds, immobilize the equipment with

these leveling parts.

Check if the equipment is completely immobilized.

Fortuitously pulling out the connection cables from the equipment will indirectly be avoided so unexpected movements will not happen.

• Regarding any interventions inside the equipment, battery cabinet and battery manipulation is a task reserved to personnel with specific or qualified knowledge only and in particular to (S.S.T.). It is mandatory to immobilize the equipment with the leveling feet- stated in the previous point, before doing any action.

Attention! Risk of tipping may happen when the battery trays are moved without stabilizing the unit first.

Do not remove more than one tray at the same time. High risk of injury may take place over the operators due to accident shock of the possible equipment falling down and/or entrapment.

• Leave a minimum of free space to cool the unit of:

25 cm at both sides.

50 cm at the rear side.

100 cm at the top side.

150 cm at the front side.

• It is recommended to leave an additional 75cm at both sides, for possible interventions of the (S.T.S.) or the requisite clearance of the connected cables to facilitate the movement of the equipment.

• Do not cut, deteriorate or manipulate the electrical cables, or do not put heavy objects on them. Any of these actions could cause a short-circuit, fire or electrical discharge.

Check if the connected electrical cables, plugs and outlets are in

good conditions.

• All electrical cables for power supply have to be fixed to the

equipment and loads, interfaces, etc..., or to immovable parts for fear of being stepped on them or becoming a medium or exposing to fortuitous pulls.

• Be careful not to wet the device because it is not waterproofed. Do not allow any kind of liquids to leak to; if it happens, shut it down immediately and contact with the (S.T.S.).

• If it accidentally contacts with liquids or high density of saline air, dry it with a soft and absorbent cloth quickly.

Check if any liquid leak to the unit and act accordingly.

• To clean the equipment, wipe it with a slightly damp cloth and then dry it. Avoid liquids sprinkling or spillage that could enter through the slots or cooling grids, which may cause fire or electric shock.

Do not clean the equipment with detergent products that contain alcohol, benzene, solvent or other inflammable substances, and needless to say they contain abrasive, corrosive liquids.

• Never manipulate the equipment with wet hands.

• If it is observed that the UPS exhausts smoke or toxic gas, shut it

down immediately and disconnect it from power supply. This incident may cause fire or electrical discharge. Contact with our (S.T.S.).

• Do not put either materials or parts over the equipment that might obstruct the synoptic visualization of the product.

• Before using the UPS for first time or after a long period

of time (6 months maximum), it has to be connected to the power supply to charge the batteries for at least 12 hours.

Although the equipment can operate with batteries discharged, you should keep in mind the possible risk of mains fault during the first operating hours. Thus, the available back up time of the UPS batteries should be lower than the expected.

2.2.2. General safety warnings.

• All electrical cables connections and disconnections of the

equipment, including the controlled ones, should be done without power supply and with switches on «O» or «Off» position.

• Pay special attention to the labelling of the equipment

that warns the «Electrical shock hazard». It indicate there are dangerous voltages inside the equipment.

Do not open, dismantle or adjust the equipment when the operating action is not stated in this document. To manipulate equipment for repairing is restricted to qualified staff only. In case of maintenance or fault, consult to the closest (S.T.S.).

A part from the implicit risk of electrical shock, any action which is not stated in this document alters the internal or external of the equipment or just only the simple intervention inside can expire the warranty.

• Some action requires to open the front door or to remove the protection cover from the terminals, i.e. erection or commissioning operation.

Once the respective actions are completed, recover the equipment to it was, with the protection cover put back and front door closed.

• To shut down the equipment completely, follow the instructions

in the start-up and shutdown chapter.

Consult the documentation before doing any action.

A wrong manipulation over the switches can cause important production losses and/or failures in the

equipment.

• Protection Earth cable of the UPS drives the leakage current of the load devices. An isolated earth cable has to be

stalled as part

of the

circuit

that

supplies

the

equipment.

Cross

cable

section and its features will be the same as the

power supply

cables, but with green strip and with or

without yellow strip.

• The protection earth must be connected to the frame or

metallic chassis of any electrical equipment, by means of the foreseen terminal (in our case to the UPS, battery cabinet when it is available and loads), assuring that it is done before turning on the input voltage.

It is essential that cables feeding the loads have their respective protection earth cable.

When circuits branches, i.e. by means of terminal strips, it is essential to have a protection earth terminal in each one of them.

• Check the quality and availability of the earth to see if it’s between

the defined parameters defined by the local or national regulations.

• During the normal UPS operation, the input power supply

cable can’t be disconnected because the earth cable of general protection in the UPS and all loads connecting at the output will be disconnected, either.

Due to the same reason, the earth cable of general protection in the building or switchgear panel that supplies the UPS will not be disconnected.

•

Cross cable sections used to supply the equipment and loads to be

fed,

ill

be followed according

to the nominal current stated in the

nameplate l

abe

l of

the equipment, and respect the Low Voltage

Electrotechnical

Regu

lations

standards

of the country.

• UPS equipment can be manufactured in four different

configurations of Input-Output:

Three phase - Three phase. Three phase - Single phase. Single phase - Three phase. Single phase - Single phase.

To correctly operate the UPS, it is necessary to use input Neutral cable or an isolation transformer between the power supply and the equipment.

• The UPS doesn’t modif y the input neutral regime at its output.

Do not earth the output neutral.

When, it is needed to modify the output neutral regime, an isolation transformer has to be located between the loads and the equipment.

• In those models with separate bypass line, an isolation

transformer has to be located in both input lines (rectifier input or static bypass), in order to avoid the direct connection of the neutral lines at both lines through

the internal wiring of the equipment.

This is only applicable when the two power supplies come from different lines, i.e.::

Two different electrical companies.

One electrical company and a generator, ...

• The installation will have input protections sized to the currents of the equipment and stated in the nameplate label. (RCD devices

type B and circuit breakers with C characteristic or any other equivalent one).

For equipment with three phase input, and connected to an IT distribution system, the protection will be with four poles in order to break the three phases and neutral in the same maneuvering.

Overload conditions are considered as a non-permanent and exceptional operating mode, so these currents will not be kept in mind when sizing the protections.

• Do not overload the UPS by connecting loads with inrush consumptions at its output, i.e. laser printers.

• Installations with redundant equipment or separate bypass line, there will be one and common RCD device only of 300 to 500mA for both lines at the beginning of the installation.

• It is recommended to distribute the output power into four lines at minimum. Each one of them will have a protection circuit breaker sized to the quarter of the nominal power. This kind of outgoing distributions will allow any fault that makes a short circuit in any device connected to the equipment to be affected to the line with the failure only. Power supply will be guaranteed to the rest of connected loads, because of the tripping of the affected line by the short-circuit only.

• Under any concept the input power cables will be connected to the output of the equipment, either directly or indirectly through other outlets.

• When supplying input voltage to a UPS with static bypass o

r separate bypass line, if the inverter is in «Off» (shutdown)

mode, it doesn’t mean no voltage at the output terminals.

To set no voltage, input and static bypass switches have to be turned

«Off».

Put warnings labels and/or emergency switches in the particular

installation if the safety norms require it.

• It is possible that the UPS supplies output voltage through the manual bypass to those equipment through either standard or optional mode under the consideration of safety.

If it is necessary to break the output supply of the equipment under this situation, turn off the outgoing distribution protection or lack it, and turn off the general protection of the distribution panel that feeds the UPS.

• All the equipment have two auxiliary terminals to install an external emergency power off button (EPO), which will belong to the end-user.

EPO doesn’t affect the power supply of the equipment, but it only breaks the power supply to the loads as a safety measure.

• RACK mounted equipment are destined to be installed in a predeter

mined

tting and to

be done b

y professionals.

Its installation has to be designed and executed by qualified personnel, who will be responsible for applying the safety

and EMC regulations and standards controlling the

particular installations and the place where the product is

destined.

2.2.3. Safety warnings regarding batteries.

• The manipulation and connection of the batteries shall be done and supervised by personnel with battery knowledge only.

If Battery circuit is not isolated from input voltage, it is dangerous to touch any part of the batteries. Dangerous voltages can be found between the terminals of the battery set and the earth. Check if there is any voltage at the input before taking any action over them.

• Before doing any action inside the UPS, disconnect the batteries. Check that no voltage is present and there is not potential danger in the DC BUS

(capacitors) o

r in the en

dpo

int of the battery set terminals.

• In equipment with separate battery cabinet, check if they are compatible before connecting them.

• When faulty batteries are found, the complete battery set has to be replaced. But with few exceptional cases in new equipment due to manufacturing faults, it will only be replaced the defective ones.

The replacement should be conducted with another battery in same type, voltage, capacity, quantity and the same brand. Otherwise there is a risk of explosion.

• Do not reuse faulty batteries. There could be a ri s k o f explosion or burst in any battery with the involved problems and issues.

• Generally supplied batteries are installed in the same cabinet, case or rack of the equipment. Depending on the power, autonomy or both, they can be supplied separately from the equipment in another cabinet, case or rack, with the interlink cables among them. Do not modify its length.

• In those equipment without batteries, their acquisition, installation and connection will be done by the end-user and it should be under his/her responsibility. Information about the batteries as regards to quantity, capacity and voltage, is stated in the battery label stuck beside the nameplate of the equipment. Respect these data, battery connection polarity and the supplied circuit diagram strictly.

For an optimum and efficient operation, the battery set has to be located as close to the equipment as possible.

• Battery voltage can involve the risk of electric shock and

can produce high short-circuited currents. Observe the following preventive measures before manipulating any terminal block identified in the labelling as «Batteries»:

Use the suitable IPE (Individual Protection Equipment):

gloves

and insulated shoes, protection glasses, suitable work clothes,

and etc.

Take off rings, bracelets or other metal hanging objects.

Use tools with insulated handles.

Disconnect the corresponding protection elements.

When connecting a battery cabinet to the UPS, respect the polarity and color of the cables (red-positive; black-negative)

indicated in the manual and labelling.

Do not place metal tools or objects over the batteries.

Risk of short-circuit and possible deflagration may

happen due to the accumulated hydrogen. Metallic particles of different sizes should be avoided due to the violent explosion of the short-circuit and/or the tool itself or the metallic object. This might result in the incident, and increase the risk of significant damage to nearby people and other devices, instruments or machines. Never manipulate them with your bare hands or through con

ducting objects. Both the battery terminal block of the equipment and the ones from the batteries are necessary. In case the automatic software to shut down the devices due to end of back up time is not set, it is recommended to shut down the loads and the UPS before depleting the autonomy of the batteries, as a preventive safety measure for the own loads.

• If the equipment is not in operation during the nighttime,

weekends and holidays periods, it is recommended to shut down the equipment completely. In particular due to this last period and safety reasons, the energy generator should be handled with care, especially to prevent batteries from unnecessarily discharging during these periods of time.

•When the equipment and/or battery module is protected by fuse

which is needs to be replaced, substitute it for another one with the same type, format and size.

•After prolonged time of disconnection, it is needed to recharge

the batteries for 12 hours at a minimum every 6 months, in order to avoid the irreversible degradation of the batteries.

•The battery terminals are requisite in order to avoid the high risk

of detriment to the equipment and batteries.

• Avoid mechanical efforts and impacts.

• Do not open or mutilate the battery. Spilled electrolyte is harmful

and toxic for the skin and eyes.

• Do not dispose the batteries in a fire or expose it to high

temperatures. Batteries may explode.

•If acid contacts with parts of the body, wash it immediately with

plenty of water and urgently call the nearest medical service.

•Batteries involve a possible risk for health and environment so the

disposal should be done in accordance with the existing regulations.

4. PRESENTATION.

4.1. VIEWS.

4.1.1. Views of the equipment.

Figures 1 to 20 show the illustrations of the equipment according to

different models, nominal operating voltages and input-output settings, which are summarized in Chart 1. Format of protections and size of the terminals shown in the figures of this document always correspond to the highest power rate model manufactured in that cabinet, at the same power supply voltage and input-output setting. Nevertheless by constant evolution of the products, some discrepancies or small contradictions might arise. So, if any questions, the labels on the equipment will prevail.

Each equipment model corresponds to one power rate, voltage, frequency and input and output currents. All values of these features can be checked in the nameplate, located at the back of the front door (PF), and act in your installation accordingly.

In the description of this manual, there are references to «LV» (Low voltage) and «HV» (High voltage) abbreviations, described in the nomenclature of the model with an «A » for «LV» and omitted «HV», grouping the following interval of voltages:

• LV.- 3x200 to 3x230 V (115 to 133 V in single phase).

• HV.- 3x380 to 3x415 V (220 to 240 V in single phase).

These abbreviations do not have any other purpose but matching and/or helping to give a better comprehension of the detailed information in this document and even they are not shown either in the nomenclature, or in the reference of the nameplate model.

All models can operate as single units or connected in parallel with other equipment of the same family because the necessary electronic kit is included.

Connection in parallel can be done at any time when the upgrading requirements are needed to increase the supplied power of the equipment or in order to have redundant operating systems for installations with higher safety.

Do not connect UPS equipment of different features versions, settings, back up times or duplicated addresses (i.e.: two equipment, although they are identical, coming from two parallel systems and with the same address) in parallel. In any parallel system only one and different address is assigned to each equipment that makes the system.

4.2. DEFINITION AND STRUCTURE

4.2.1. Structural diagram.

To describe the operating principle, it is taken as a reference and example the single line diagram of Fig. 25 and 26, corresponding to

UPS with three-phase input and output setting, one with basic structure and the other one with separate bypass line. All the equipment works and operates in the same way, although

they have common line or separate static bypass.

4.3. UPS FUNCTION STAGES.

This UPS series is structured in the following stages:

• I/O EMI filters.

• Rectifier-PFC (AC/DC).

• Batteries.

• Inverter (DC/AC).

• Static Bypass.

• Maintenance or manual Bypass.

• EPO emergency shutdown.

• Control panel.

• Control and communication Software.

4.3.1. I/O EMI filters.

EMI filter is a three phase low-band filter, whose function is to

attenuate and cancel all the radio frequency perturbations. The filter performs in a bidirectional way:

• It cancels the perturbations that come from the line and protect the UPS control circuits.

• It avoids the possible radio electrical perturbations that the UPS generate through the line and affect other equipment connected to it.

4.3.2. Rectifier-PFC stage (AC/DC).

Constructive parts:

• Input protection and switch: it is the particular protection of the PFC rectifier.

• Current sensor: it uses alternating current transformers to measure and control the input current, to get a THDi < 3% at full load condition and even < 1% depending on the quality of mains.

• “T” filter: it is used to attenuate the current ripple caused by the PFC switching.

• IGBT's three phase bridge: it will be used to make the AC/ DC conversion with the lowest distortion and highest ef ficiency. To do that, it is used the Trench-gate IGBT technology of 4th generation.

• Input chokes: They are used by the PFC rectifier as energy storage elements (in switching times), for the AC/DC conversion.

• DC Bus: it is used to filter the DC needed for the correct operation of PFC converter and inverter.

4.3.3. Batteries.

This UPS series has a battery set that stores energy during the normal operating mode (present mains) and they are discharged during the emergency operation (mains fault), keeping the critical loads running during the required time.

Batteries are sized to supply full power to the assigned critical loads during the back-up time for any load condition. Standard batteries are sealed Lead Acid, maintenance free and VRLA technology.

Each cell or cell group (battery block) are duly marked in a permanent way, with polarity indication, voltage and safety warning required by the standard.

Cells are duly assembled and electrically connected. Battery set is protected by means of a fuse holder with ultra fast fuses, ready for

the described conditions in section «4.3.2. Rectifier-PFC stage».

In normal operation (mains present and charged batteries), the battery set is working on floating voltage.

As an option the battery set of Pb-Ca or Ni-Cd can be assembled in a cabinet or rack separately from the equipment, shared for systems made of two UPSs in parallel.

4.3.4. Inverter stage (DC/AC).

Constructive parts:

• DC Bus: it is used to filter the DC and it is in charge of interconnecting the PFC and Inverter through the protection fuses.

• IGBT three phase inverter bridge: it is equal to the PFC stage but in counter way, it is in charge of making the DC/AC conversion with the lowest distortion and highest ef ficiency. It is also using the Trench-gate technology of 4th generation.

• Current sensor: as it has been described before, in this case

conventional AC currents sensors are also used (current transformers) for measurement and control the output current of the inverter to get a total harmonic distortion at the output voltage lower than 1% in full load conditions.

• Output chokes: Use identical solution as the input. These chokes are used by the inverter as energy storage elements (in switching times), for DC/AC conversion.

4.3.5. Static bypass st

age

When the inverter can't keep the voltage to the critical loads due to overloads, short-circuits, current limits or faults, the UPS has a bypass circuit, which supplies isolation for the inverter and supplies the critical loads directly from electrical mains.

The UPS controls the availability of inverter and bypass mode permanently in order to make the shifting between them. The bypass stage is based on six double thyristors in semipack format, working as AC switches, three of them are for shifting the

input over the output and the other three are for shifting the inverter over the output. The managing system of the SCR switches is based on drivers designed with a shifting system that responds to the following requirements:

Full static shifting system. Shifting with no high transient currents. Shifting with no transfer time.

The control algorithm of the triggering signals of the thyristors assures a nil transfer time, and avoids short-circuits between the thyristors of bypass and inverter (shifting with zero cross current).

4.3.6. Maintenance or manual Bypass.

All UPSs from this series are foreseen with an auxiliary line protected by a circuit breaker switch, which makes an electrical bridge between the input and output terminals. Managing this switch, properly together with the input and output, allows isolating electrically all the UPS elements from the electrical lines. The type of maneuvering of the maintenance bypass is “make before break”, with the purpose of keeping the critical loads fed, even during the maintenance tasks.

4.3.7. Terminals for EPO.

The UPS has two terminals to install an external button of emergency output shutdown (EPO).

4.3.8. Control panel.

This UPS has a sophisticated control panel based on a DSP (Digital Signal Processor) that performs as interface between the UPS and end-user.

Each UPS is equipped with an alphanumerical LCD panel, which automatically informs the end-user of the current status of the equipment and electrical measurements. It is based on a tree diagram, allowing an easy browsing through its screens.

4.3.9. Control software and communications.

AFC Control (Adaptive Feedforward Cancellation).

It consists in the use of digital resonators connected in parallel and set to those frequencies where the consigns or perturbations to refuse are expected. This control technique allows doing the follow of the sinewave signals of reference of the output voltage in the inverter and input current of the active rectifier. It is important to highlight that the different controls of the UPS

do not operate either independently or locally, but they interact between them in such a way that it is an overall controller of coupled type. It means operating advantages like to adapt the

rectifier to the load conditions immediately. The digital control software works at two different levels:

4.3.9.1. Control software at low level.

• Input three-phase rectifier controller: PFC control and

battery charge loops. The structure adopted of independent control per phase of cascade type allows managing both single phase and three phase inputs.

The AFC control technique has also been applied, to assure a sinewave mains currents, with a THDi < 2%, and in phase shifting with the voltages, to balance the active power of all the system, to accelerate its response and make it insensitive to the load transients.

In normal conditions, the rectifier is running and charging the batteries, controlling the charging current and floating voltage at any moment according to the temperature of themselves. The system is also in charge of minimizing the charging current ripple that flows through them.

When the input voltage or frequency is out of the correct operating range, it is shut down and batteries are responsible for keeping the inverter in operation. Meanwhile, they supply the loads connected at the output of the equipment till the battery voltage decreases at the end of back-up time.

Another important feature of the rectifier is its bidirectional capacity in operation. This allows consigning a battery discharging current even with existing mains. This quality performance will make it possible to do a battery test both in full load and in no load conditions.

• Output three- phase rectifier controller: being independent

per phase, it is easily adapted to different settings, either single phase or three phase.

It highlighted the use of the AFC control technique that allows getting an output voltage with a THDv lower than 1,5% in nonlinear load at the output and good dynamic response against unexpected step loads.

• Switching algorithm of the bypass thyristors.

• Parallel control: high speed communication and inverter

parallel connection.

4.3.9.2. Managing software of the equipment.

Managing and control of different parts. Visualization software for user interface. Software of communication and protocol implementation. Managing software of parallel system.

4.3.9.3. Communications.

• COM port to relays: It supplies a digital signals in a dry

contact way, which makes the dialogue between the equipment and other machines or devices possible.

By default the equipment is supplied with 4 signal relays with a preset programming (see chart 2), which can be modified at factory or by the S.T.S. upon request. Chart 6 shows all the alarms that can be set to any relay. A fifth relay can be supplied as an option and upon request, which can be defined in the purchase order.

Also there is a “shutdown” input that allows shutdown the inverter.

The most common use of this type of port is to supply the

necessary information to the closing file software.

• COM port RS-232 and RS-485: By means of the same DB9 connector supplies the RS-232 and RS-485 communication ports. They are mutually exclusive between them and they are used to connect the UPS with any machine or device that has this standard bus.

The RS-232 port consists in the serial transmission of data, in such a way that it can send a lot of information through a communication cable of 3 wires.

The RS-485, unlike other serial communication channels, it uses 2 wires only to dialogue among the systems connected to this network. The communication is established by sending and receiving signals in differential mode, so it gives the system high immunity against the noise and long range (approx. 800m).

The used protocol is “MASTER/SLAVE” type. The computer or IT system (“MASTER”) asks for a determined data, and the UPS answers immediately (“SLAVE”).

4.4. OPERATING PRINCIPLE OF AN EQUIPMENT.

This UPS series is a double conversion system AC/DC, DC/AC with sinewave output that supplies a safe protection in extreme conditions of electrical power supply (fluctuations of voltage, frequency, electrical noises, blackouts and mains faults,

etc.). Whatever type of load to protect is, the equipment is ready to

assure the quality and uninterruptible electrical power supply.

The use of the transformerless technology allows a significant reduction of weight and volume in the equipment, by improving important co-efficiency a lot like the power/footprint ratio.

• Basically its operating is the following: The rectifier, an IGBT three phase rectifier, conver ts the AC voltage in DC by draining a sinewave current (THDi <2%), charging the batteries with constant current/voltage.

Batteries supply the energy required by the inverter in case of mains fault.

The inverter is in charge of converting the DC bus voltage

in to AC by providing an alternating sinewave output, stabilizing voltage and frequency, ready to supply the loads connected at the output. The basic structure of double conversion is complemented with two new functional stages, static bypass switch and manual bypass switch. The static bypass switch connects the output load with bypass line directly in special conditions like overload or over temperature and it is reconnected to inverter again, once the normal conditions are restored. UPS B version has two separate lines for the

rectifier and bypass stages increasing in the safety of the installation, because it allows the use of a second line (generator set, other company, etc...). The manual bypass switch isolates the UPS from mains and loads connected at the output, so the maintenance tasks can be done inside the UPS without interrupting the supply to the loads.

4.4.1. Normal operating ().

With mains present, the rectifier converts the AC input voltage into DC, by boosting the DC voltage to an optimal level to feed the inverter and battery charger.

The inverter is in charge of converting the DC bus voltage into AC by providing an alternating sinewave output, it stabilizes the

voltage and frequency, ready to supply the loads connected at the output (Fig. 20 and 21).

4.4.2. Mains fault operating ().

In case of mains fault or blackout, the battery set supplies the needed energy to feed the inverter. The inverter still operates normally, without noticing the lack of

mains and the back-up time depends on the capacity of the battery set only (Fig. 20 and 21). When the battery voltage reaches the low voltage, the control blocks the output in order to protect the batteries from being deep discharge. When mains is restored and after the first analysis, the UPS goes back to operate as it is described in the previous

section «4.4.1. Normal operating».

4.4.3. Operating with non-active inverter ().

The inverter is non-active due to alarm conditions like overloads, over temperatures, etc... In this case the rectifier is still charging the batteries in order to keep their optimal charge status. The inverter is also non-active if the start-up has not been done

through the keypad of the control. In both cases, the output voltage of the UPS comes from the emergency bypass line through the static bypass switch (Fig. 20 and

21) in the condition that the EPO is inactive.

4.4.4. Manual bypass operating ().

When it is required to make any maintenance service to the equipment, it can be disconnected from mains without breaking the power supply of the system and affecting the critical load.

The UPS can only be intervened by technical or maintenance staff, by means of the manual bypass switch (respect the corresponding operative instructions stated later on).

4.4.5. Smart Eco-mode operating.

For those applications with lower requirements, the smart and efficient function «Smart Eco-mode», meanwhile the power supply is available, allow the equipment to feed the loads directly from mains through the solid static bypass state («Off Line» mode). In case of mains fault, the system will automatically shift to normal operating mode («On Line») and will supply the loads through the inverter with the energy of the batteries. The «Smart Eco-mode» operating mode improve the ef ficiencies between 4 and 4.5 % highest than «On Line» normal mode, so it is close to 100 %. The «Smart Eco-mode» operation does not ensure a perfect stabilization in frequency, voltage or sinewave shape (distortion)

as in «On Line» normal mode, because the figures of these parameters depend on the static bypass line and preset activation ranges completely. The detection of these parameters can take up to 3 ms, so it is recommended to assess the advisability of using this operating mode, depending on the level of protection required by the loads.

This operating mode is disabled from factory and the end/user can activate it if needed, according to section 7.2.2. and Fig. 35.

This operating mode is disabled from parameters and the end/user can activate it if needed

4.4.6. Frequency converter operating.

This UPS can be set from factory as frequency converters, whether they has batteries or not, being able to operate from 50 to 60 Hz or

vice versa. The equipment is set as frequency converters, so the static bypass and manual bypass are not available. So, those functions, measurements, alarm messages, parameter settings, as well as maneuvering of the related switches will not be

operative and they will not be taken into account.

4.5. OPERATING STRUCTURE OF A PARALLEL SYSTEM.

This Uninterruptible Power Supply Systems series is designed

and thought as «parallel» connection with a maximum of four units, in the condition that they are the same model (setting, voltage, power, frequency, back-up time, ...), all of them without adding hardware. Fig. 22 and 23, as examples, show the circuit diagrams of a three-phase input/three-phase output parallel system, with and without separate static bypass line. Both circuit diagrams are only showing the input-output power connections and the parallel control BUS.

A part from the possible setting, conceptually, the parallel systems are divided into two similar structures and at the same time very different depending on the application.

Systems connected in parallel or active parallel, supply the loads equally among them. Less when there is only one UPS, the system will be able to be redundant or non-redundant depending on the needs and requirements of the application.

• Simple parallel system (non-redundant): a non-redundant parallel system, is that one where all UPSs supply the required power by the loads. Total power of the system based on N equipment of nominal power rate Pn, is N x Pn.

If the system is operating with a load close or equal to the maximum and one of the faults, the load will be shifted to bypass automatically with “ make before break technique”, because it will not be able to support the consumption demand due to the overload that it will be caused in the rest of UPSs.

• Redundant system: a redundant system is that one has one or more UPSs than the minimum required by the total power of the system (depending on the redundancy level), being the load fair shared among them. So, the fault of any of them will cause the damage that UPS will be out of the system and the rest will continue supplying the load with all the guarantees. Once the damaged UPS is fixed, it can be connected to the system in order to recover the redundant condition.

A system with his configuration increases the reliability and assures a quality of AC power supply for the most critical loads.

The quantity of redundant equipment to be connected has to be studied according to the requirements of the application. No matter Parallel connection is redundant or not, it adds several advantages apart from the connection itself:

• Higher punctual power and back-up time: in a parallel system of N+M equipment, it is considered the nominal maximum load of N equipment and +M are the reserve ones,

so:

N, is the quantity of equipment in parallel,

corresponding

the minimum quantity required by the total needed power.

+M, is the additional quantity of equipment corresponding

to the residual safety power (redundant equipment). Although, in practice it can drain the total power in which the N+M

system can supply, the redundancy requirement or

conception

does not advice it and in compensation there is a surplus of dynamic power against load demands. i.e., a redundant parallel system with 3 UPS of 40 kVA and N+1 configuration, the nominal maximum load contemplates 80 kVA (2x40 kVA), although the system can accept load demands up to 120 kVA (3x40 kVA).

Therefore, the fact of having +M reserve equipment, increases

the back-up time of the set because the battery set is higher.

• Modularity: capacity can be added to a UPS parallel system by adding equipment of the same feature, without needing to replace the equipment already installed. i.e., if time later, an installation with a parallel system of 2 UPSs is detected that the capacity of this system is not enough, it can be opted for adding a third equipment to the system, without replacing the 2 original equipment.

The UPS parallel system management of UPS series is done by a MASTER-SLAVES protocol, where only one equipment (MASTER) takes the control of the rest ones (SLAVES). So, the control of the output voltage, bypass shifting, disconnections, mains synchronization are managed by the MASTER equipment, and transmitted to the SLAVES equipment through the management bus of the parallel system.

This MASTER or SL AVE condition is dynamic as it is described later and it will depend on several factors (initial status of the equipment, chronological order of commissioning or shutdown of the system through one equipment or other)

5. INSTALLATION.

• Read and respect the Safety Information, described in

section 2 of this document to obviate some of the stated indications which may cause a serious or very serious injuries to persons in direct contact or in the vicinity as well as break-downs in the equipment and/or loads connected to itself.

• Unless the opposite is indicated, any action, indications,

premises, notes and others, are applicable to UPS equipment, no matter it may belong to a parallel system or not.

5.1. RECEPTION OF THE EQUIPMENT.

• It is dangerous to handle the equipment over the pallet

without much prudence, because it could overturn and cause serious or very serious injuries to the operators if any fall and/or trapping occurs. Pay attention to section

«2.2.3.1. To keep in mind» as regards to handling,

moving and location of the unit.

• Use the most suitable medium to move the packaged UPS,

with a pallet truck or fork lifter.

• Pay attention to the weights of handling equipment according

to the model stated in the technical specifications in section «9. Annexes».

5.1.1. Reception, packaging and contents.

• Reception. To check:

Data label stuck o n the package corresponds to

the ones stated in the purchase order. Once the UPS is unpacked, check the purchasing details with the one in the nameplate of the equipment,

stuck

at the back of the front door (PF).

If any discrepancies exist, make the nonconformity as soon as possible, by quoting the serial number of the equipment and the references of the delivery note.

No incident has happened during the transport (packaging and impact indicator are in perfect status). Otherwise,

follow the protocol stated in the label attached to the

impact indicator, located on the packaging.

• Unpacking.

Check

the content before deserting the packaging.

Unpack the package according to the «Un

cable bundle per equipment.

• Once the reception is finished, it is advisable to pack the UPS again till its commissioning in order to protect it against

mechanical impacts, dust, dirt, etc.

• The packaging of the equipment has a cardboard pallet or wooden type depending on the case, expanded polystyrene corners, bag and polyethylene strip, all of them are recyclable materials. When it is required to dispose them, do it in accordance to the regulation in force.

It is advisable to keep the packaging for 1 year as minimum.

5.1.2. Storage.

• The storage of the equipment should be in a dry and cool place,

and protected from rain, dust, water jets or chemical agents. It

is advisable to keep each equipment and battery set inside their original packaging because it is designed to assure the

best protection during transport ant storage.

• In general, less particular cases, the UPS has sealed lead

acid batteries and their storage must not exceed 6 months without recharging them (see last section of charge, the label stuck in the packaging of the equipment

or battery set). Lapsed this period of 6 months, connect the equipment to mains together with the battery set if any, paying attention to the safety instructions and connection.

Models with separate static bypass line is not necessary to connect with this power terminal strip.

Proceed to start it up as it is described in section 6, do not turn «On» the output switch (Q2), and do not start up the inverter through the control panel (PC).

Leave the equipment in this mode for 12 hours at minimum. Once the battery recharging is finished, proceed to shut down the equipment, disconnect the electricity and store the UPS and batteries if any, inside their original packaging. Regarding the battery recharge, units that belong to a parallel system will be treated as single equipment, so it is not

necessary to add any connection.

5.1.4. Location, immobilization and considerations.

5.1.4.1. Location for single equipment.

• As i.e. Fig. 24 it shows two typical cases depending on the m

ode

l. For a single cabinet, UPS contains batteries inside, and the other with batteries in another cabinet to extend its back-up time.

For extending back-up times with more than one cabinet, it is recommended to put one at each side of the equipment in case of having more cabinets repeat the same sequence alternately.

As minimum, leave enough space for cooling the unit

with:

- 25 cm at both sides.

- 50 cm at the rear.

- 100 cm at the top.

- and 150 cm at the front.

It is recommended to leave an additional 75 cm free at both sides, for the possible interventions of the (S.T.S.), or the needed length of the connection wires to make it easier to move forwards.

Fig. 24. Floor view with minimum distances for a UPS.

5.1.4.2. Location for parallel systems.

• As i.e. Fig. 25 it shows 4 UPSs in parallel with their respective

battery cabinets. For systems with less units act in each case accordingly.

• It is advisable to put them in order by the number stated in the door of each equipment. The number corresponding to the assigned address preset from factory.

The arrangement is not random. It is ideal to have the battery wires in length of 3.5 m and communication BUS in 5 m. For a higher quantity of battery cabinets in systems with extended back- up time, follow the same criteria to keep the symmetry.

• When the system is structured by models with batteries and power electronics in the same cabinet, ignore the illustrations of battery modules.

Always respect the distances stated in Fig. 25, and the quantity of cabinets that sets the system.

5.1.4.3. Equipment immobilized and levelled.

• All UPSs and battery modules with casters, have 4 stabilizer

elements (PB), arranged next to each caster.

• The purpose of the stabilizers elements (PB) is to lay, immobilize and level the metallic cabinet once it is located, in order to avoid possible overturns, in particular with those whose battery shelves can be extracted.

Warning! Danger of turning over when extracting the battery shelves without stabilizing the unit in advance. Do not extract more than one shelf at the same time, or high risk of serious injuries to the operators may cause the possible impact of falling and/or trapping of the equipment.

• Loosen the elements (PB) by turning them counterclockwise as high as it is off the floor with the help of a spanner, and loosen them more than half turn in order to immobilize the metallic cabinet with a correct levelling.

Fig. 31 shows where the stabilizers elements (PB) have to be finally fixed.

• To have access to the battery shelves, cabinet side covers have to be removed and they have to be unblocked. Shelves can be extracted through both sides and each one has a stopper.

5.1.4.4. Preliminary considerations before connecting.

• The description of this manual refers to the connection of terminals

and switching maneuvering that is only available in some versions or equipment with extended back-up time. Ignore those operations if the unit does not have them.

• Follow and respect the instructions described in this section referred to the installation of a single equipment or parallel system.

• Switchgear or external manual bypass panel boards:

It is advisable to have an external manual bypass panel board equipped with input, output, static bypass (UPS-B version only) and manual bypass protections, in single installations. For parallel systems up to two units, it is very advisable having a switchgear panel board and for systems with 3 or 4 equipment, it is essential. Switches of the panel board have to allow isolating the UPS from the system against any wrong operation and feed the loads with the rest ones, either during the preventive maintenance period or the reparation of itself.

• Upon request an external manual bypass panel board for a single equipment or parallel system can be supplied.

Original position from factory

of the element (PB).

Element (PB) tighten

against the floor.

• If it requires more detailed information for particular

system configuration, ask for the relating information in «Recommended installation». It shows the circuit diagram, as well as the protection size and minimum cross section of the wires that are connected to the equipment, taking into account the nominal operating voltage. All figures are calculated for a maximum total cable length of 30 m between the distribution panel board, equipment and loads.

Fig. 26. Equipment / battery module stabilizers elements (PB).

• Equipment maintenance and battery handling is a reserved task to the S.T.S. or authorized staff.

If for any reason, the battery sliding shelves are in use or any intervention, it is essential to pay attention and respect the indications of the label stuck in each shelf, before extracting them (see Fig. 26).

For longer lengths correct the cross sections accordingly, in order to avoid dropping voltages, by respecting the Regulations or norms corresponding to the country. For each setting in manual and the information is available

for «N» units in parallel, as well as the features in «Backfeed

protection».

• In parallel systems, the length and cross section of the wires that goes from the panel board to the each UPS and vice versa, will have the same for all of them, without any

exception.

• Always take into account the cross cable section, as regards to the

size of the terminals of the switches, in order to embrace all their section properly for an optimal contact between both elements.

• In the nameplate of the equipment, nominal currents are only

printed as it states in the EN-IEC 62040-1 safety standard. The input current calculation, has been taken into account the power factor and the own efficiency of the equipment.

• If other peripheral elements are added to the UPS or parallel system

input, output or bypass like transformers or autotransformers, take into account the currents stated in the own nameplates of those elements in order to use the suitable cross sections, always respect the Local and/or National Low Voltage Electrotechnical Regulations.

• When a UPS or parallel system include a galvanic isolation

transformer, as standard, option or installed by yourself, either at the input line, bypass line, output or in all of them, protections against indirect contact (RCD) have to be fitted in at the output of each transformer, because in case of electrical shock in the secondary winding (output of the isolation transformer), its isolating feature will block the tripping of the protections located in the primary winding.

• As a reminder, all isolation transformer installed or supplied from

factory, has the output neutral connected to earth by means of a bridge that connects the neutral and earth terminals. In case, an isolated neutral is required to remove this bridge by following the precautionary measures stated in the respective local and/or national low voltage regulations.

• To reach the cables inside the cabinet, there are either cable glands

(PR) assembled in the metallic structure or an only one opening as a register mode.

• Models with power rate higher than 40 kVA (LV) / 80 kVA (HV),

have a rod to fix the connection wires of the equipment to it, by means of clamps (BF).

Once the cables are connected to their respective terminals, proceed to fix them by means of clamps to the rod (BF).

5.1.4.5. Preliminary considerations before connecting, as regards to batteries and protections.

• Battery protection has to be always done by fuses as minimum. So, the physical layout of them is determined by the tangible

location of the batteries.

Standard equipment up to 20 kVA (LV) / 40 kVA (HV), batteries are supplied already fitted in the same cabinet of the equipment and B1 models and/or higher power rate are supplied in a separate cabinet. Therefore, battery protection is

arranged as follows:

In the UPS (stated in this document as (Q3)):

Battery fuse holder switch with 3 fuses in models up to 20 kVA (LV) / 40 kVA (HV) or switch for B1 versions and higher power rates.

In the battery cabinet and standard back up time:

Battery fuse holder switch with 3 fuses in models up to

60 kVA (LV) / 120 kVA (HV) stated in this user's manual

as (Q8).

Switch for battery string no 1 in models higher than 60 kVA

(LV) / 120 kVA (HV) stated in this user's manual as (Q8). Inside there are 3 non-switchable fuses.

• In relation to fuses, they will be supplied inside a plastic bag with the equipment documentation or inside the battery cabinet, less those battery modules of models higher than 60 kVA (LV) / 120 kVA (HV), which are mechanically fixed to the cabinet.

• The original type of the battery circuit is preset op e n from factory..

– +

Put the fuses in the corresponding fuse holder switch and turn it «On» when it is indicated only, never before. To

operate in other way, it can cause irreversible damages to the equipment or serious and/or very serious injuries to

the fitter, as he has been exposed to a possible electrical discharge during the connection of the UPS with the battery set or battery cabinet.

• Do not maneuver the battery fuse holder and/or switch

when the equipment is turned on. This mechanisms cannot be turned on/off with load.

• When power supply to the equipment or parallel system

is broken in a short intervention and it is planned to have them out of service for long time, shut them down completely and remove the 3 fuses from the fuse holder

switch or battery module for higher safety, and keep them in a safe place. For models higher than 60 kVA (LV) / 120 kVA (HV), open the battery switch in both cabinets (equipment and battery module).

5.1.4.6. Access to inside of the cabinet for connection.

• Any equipment and battery cabinet from this series has

terminals as connection for the power. Also UPSs have terminal strips for the auxiliary connections and HDB9 / DB9 communication connectors.

To access to them, follow and repeat the same procedure in each unit for parallel systems:

Unblock the lock/s (CL) with key (LL) supplied in the equipment, turn it clockwise to 45º.

Open the front door (PF) completely. DB9 connectors of communication ports and terminals for EPO remote button

are visible.

Remove the screws (t1) that fix the terminal cover (TB) to the cabinet and connection terminals are visible.

When finishing the UPS connection, put the cover (TB) back, fix it with the screws (t1), close the door (PF) with

the key (LL) and lock (CL).

Take into account the cross cable section, as regards to the size of the own terminals of the switches, in order to execute

all their section properly for an optimal contact between both elements.

5.2. CONNECTION.

• This equipment is suitable to be installed in mains with

power distribution system of TT, TN-S, TN-C or IT. Take into account the installation of the used system and the

national electrical regulation of the destination country.

• The base of front door (PF) has a slot to facilitate the entering and way out of the communication cables inside the UPS. Watch to not trap them between the door and cabinet when closing it.

5.2.7. RS-232 and RS -485 COM ports. Connector (X31).

• The communications line (COM) is a very low voltage

circuit of safety. To preserve the quality, it must be installed separate from other lines that have dangerous voltages (power distribution line).

• In the same DB9 connector there are supplied both communication ports of the equipment, the RS-232 and RS-485. Both ports cannot be used at the same time, because they are mutually exclusive.

• Both channels are used for connecting the UPS with any machine or devices that has this standard bus.

The RS-232 consists of the transmission of serial data, so it is possible to send a large amount of information through a communication cable of just 3 wires.

• Physical structure of the RS-232.

Pin 2. RXD. Serial data reception.

Pin 3. TXD. Serial data transmission.

Pin 5. GND. Ground signal.

• Physical structure of the RS-485.

Unlike other serial communication links, this uses only 2 wires (pins 4 and 9 of the female DB9 connector) to make the dialogue among the systems connected to the network. The communication will be established by sending and receiving signals in differential mode, which gives the system great immunity to noise and a long range (approx. 800 m).

Pin 4. Output signal A (+) of the RS-485.

Pin 9. Output signal B (–) of the RS-485.

• Communication protocol.

The communication protocol used is «MASTER/SLAVE» type. The computer or computer system («MASTER») asks about a certain data, and the UPS («SLAVE») answers immediately with the required data.

If this communication way, is going to be used, ask for the

protocol IN467*00.

Firstly the communication channel of the computer will be programmed with the same parameters as the communication channel of the UPS.

Then we will be ready to start the communication and therefore send to the UPS the first question.

Fig. 30. DB9 connector (X31) and (X32).

• By default the equipment is supplied with 4 signal relays with a preset programming (see chart 2), which can be modified at factory or by the S.T.S. under request. Chart 6 shows all the alarms that can be set to any relay. A fifth relay can be supplied as an option and under request, which can be defined in the purchase order.

Also, there is a «Shutdown» input that allows turning of f the inverter, when there is a voltage between (5÷ 12 V) at this input.

• The most common use of these kinds of ports is to supply the necessary information to the file closing sof tware.

If there is any problem meanwhile communicating, it will be advisable to repeat the initialization sequence of the channel.

• The

communication parameters o

f the RS-232 and RS-485 are:

Baud rate: 1200, 2400, 4800, 9600 or 19200 Bauds.

Nr of data bits: 8 Bits.

Nr of stop bits: 1 or 2 Bits.

Type of parity: Even, Odd or None.

• The base of front door (PF) has a slot to facilitate the entering and way out of the communication cables inside the UPS. Watch to not trap them between the door and cabinet when closing it.

5.2.8. EPO terminals (X50).

• All UPSs have two terminals to install an external emergency button to shutdown the output (EPO).

• In case it was required to install a switch or button (EPO) in a single equipment, the cable bridge that closes the circuit has to be removed from terminal strip (X50) first.

• For a parallel system, two different solutions can be applied, which are the following:

Connect the button (EPO) in only one equipment of the

parallel system. Remove the cable bridge from terminals

(X50) in the equipment that it is only connected.

In case of fault and removing of the equipment that has physically connected the button (EPO), there is the risk of leaving the system without the emergency stopping, unless it is reconnected to the other operative UPSs.

Connect a button (EPO) to each equipment of the parallel system. To do that, remove all the cable bridges from terminals (X50) in each equipment.

Therefore, the functionality of the (EPO) will be kept in each one of them, regardless what occurs in the rest of

equipment of the parallel system.

By means of the own communication BUS among the

equipment that make the parallel system, any action over any

button will affect to the whole.

• In any case, the switch or button (EPO) has to be normally closed (NC), so the emergency shutdown order will be triggered when opening the circuit between these terminals (X50).

To restore the UPS to normal mode, invert the position of the switch or button (EPO), -close the circuit between the terminals (X50)-, unblock the button.

• To know the operating of (EPO), see section 6.6. of this manual.

• The base of front door (PF) has a slot to facilitate the entering and

way out of the communication cables inside the UPS. Watch to not trap them between the door and cabinet when closing it.

(Output Emergency Shutdown)

Fig. 31. Connection terminals for emergency shutdown switch or

button (EPO), belonging to the end/user.

5.2.9. Auxiliary contact and battery temperature probe terminal strip.

• All the equipment are provided with terminal strip that

corresponds to the auxiliary contacts of manual bypass (X51) and output (X45) switches.

• Also in the equipment either with separate battery cabinet

(models >20 kVA (LV) / >40 kVA (HV)), the additional

terminal strip (X34) are supplied, to connect the battery temperature probe that allows compensating the floating voltage according to the ambient temperature.

• Any wire connected to the terminals (X34), (X45) and (X51), will be entered into the equipment through the cable bushing (PR).

5.2.9.1. Terminal strip, auxiliary contact of manual bypass switch (X51).

• Terminal strip (X51) of two pins of the UPS, is connected in parallel with the normally opened auxiliary contact of the switch or manual bypass switch of the equipment.

• Switchgear panel board with manual bypass manufactured by us (option), there is a terminal strip of two terminals connected in parallel with the normally opened auxiliary contact of the switch or manual bypass switch of the own switchgear panel board. Any auxiliary contact of the manual bypass are moved on in advance when closing.

• In case of acquiring a switchgear panel board with manual bypass in another way, check that it has the stated auxiliary contact and connect it to the terminal strip (X51) of each equipment. As a must, the auxiliary contact has to be moved on in advance when closing.

• It is ESSENTIAL as safety measure of the system,

loads included, to connect the terminal strips (X51) of

the UPSs with the terminal strip with the same functionality of the switchgear panel board. This way, any wrong action

over any switch or manual bypass switch of the turned on UPSs will avoid causing a total or partial fault of the installation, loads included.

5.2.9.2. Terminal strip, auxiliary contact of output switch (X45).

• This terminal strip of two pins is available in any equipment, but it is useful in parallel systems only.

• Basically, the normally opened auxiliary contact of the output switch, is extended till the terminal strip of two pins (X45). Through the isolated cable as a bridge mode that is supplied

connected between both pins, the circuit is closed. Do not remove in single equipment, because although the equipment would be in operation, there would be an alarm of output switch deactivated.

• In those installations with parallel systems, the cable as a bridge mode connected between the two pins of the terminal strip (X45) of each UPS has to be removed, and connected to the terminals

corresponding

to the auxiliary contact of the output

switch of the switchgear panel board.

• In case of acquiring a switchgear panel board by yourself, check if the output auxiliary contact is available and connect it to the terminal strip (X45) of each equipment. As a must, the auxiliary contact has to be moved on in advance when opening.

5.2.9.3. Terminal strip, battery temperature probe (X34). For batteries in a separate cabinet only.

• As the battery manufacturer recommends a variable floating voltage depending on the ambient temperature.

The control of this feature will be done through the measurement of the temperature by means of a probe, located inside the cabinet itself when batteries and equipment are fitted in the same enclosure.

For those cases that batteries are supplied in a separate cabinet out from the own UPS (models >20 kVA (LV) / >40 kVA (HV),

there will be a terminal strip of two pins (X34), that allows

bringing the probe located at the end of a two wires bundle with

4.5 m., till inside the battery cabinet.

The connection of the two wires from the cable bundle to the terminal strip (X34) does not have polarity.

• Also via this probe the ambient temperature inside the battery cabinet can be visualized in the control panel with LCD.

• The bundle with the probe will always be supplied already connected to the terminal strip (X34), so it is only necessary to cut the clamp that keep it rolled, to take it out from the UPS cabinet and enter it into the battery cabinet, in both cases, through the foreseen cable bushing (PR).

5.2.10. Connection of parallel BUS (X36i) and (X36o).

• This section is only useful for parallel systems.

• For the correct operation of the parallel functions and operating,

any unit connected in parallel are continuously communicated among them. It is achieved by means of the called communication line or BUS.

• Any operation of this section, regarding parallel systems, has to be done by authorized staff of our firm.

• Once the power connections of the UPSs of the parallel systems are done, it is needed to make the ones related to the control or communication BUS. To do it, connect them in a sequential way, two lines of the communication BUS between a unit and its adjacent.

• Together with each UPS of a parallel system, it is supplied a 15

wires bundle with HDB15 connectors at both ends, one male and the other one female, with a length of 5 m. Therefore, there will be as many communication BUS bundles (BC), as quantity of equipment to parallel have the system.

See Fig. 6 to 14 for COM

port physical layout.

Fig. 32. Connection of the communication BUS.

5.2.10.1. Connection of the

communication

or BUS bundle

(BC).

• Respect the sequence and connection order of the

communication BUS among correlative equipment.

Although the order of the connections of communication BUS among equipment are made, is not important, on condition that the communication loop is completed or closed properly, it is advisable to carry out the connections with the immediately next equipment in order simplify the connection.

• The connection limit of the installation, will be determined by the quantity of available equipment to parallel and in any case till a maximum of four units.

• Each equipment has two HDB15 connectors for the communications among them, one male labelled as “Output”

(X36

) and another one female as “Input” (X36°).

• In the same way, all the bundles supplied with the equipment,

are equal in connections and length.

DO NOT MODIFY THE COMMUNICATION

BUS

BUNDLE, OR THE CONNECTORS UNDER ANY

CONCEPT.

• Take one of the bundles and insert the HDB15 female connector

located in one of its ends, into the male connector labelled as

“Output” (X36°

), in any of the equipment of the system and

insert the HDB15 male connector located in the opposite end of

the bundle into the female connector labelled as “Input” (X36 )

Of the adjoining equipment.

• Repeat the previous step with each equipment of the system, till closing the communication BUS loop or ring.

• As an example, Fig. 32 shows, how the communication BUS connections have to be done.

Although this illustration is not representative for the complete UPS series, as for the format of the cabinet, terminal layout or size and/or switches, as well as the own communication ports, it expects to be a guide to clarify the possible doubts on how the communication loop has to be connected.

To see the physical layout of the COM connectors for each power rate, refer to the illustrations of figures 6 to 14.

• The base of front door (PF) has a slot to facilitate the entering and way out of the communication cables inside the UPS. Watch to not trap them between the door and cabinet when closing it

6. OPERATING.

• During the description of this section, it is detailed the procedure to follow to get the different functionalities, considering a system of «n» equipment connected in parallel.

If in your case, it is available only one UPS from UPS, series, proceed in the same order, but simplifying the operating for a single unit.

• As it has been stated before, it is advisable to have an

external manual bypass panel board equipped with input, output, static bypass (UPS B version only) and manual bypass protections, in single installations.

For parallel systems up to two units, it is very

advisable

having a switchgear panel board and for systems with 3 or 4

equipment, it is essential. Switches of the panel board

have to allow isolating a UPS from the system against any

wrong operation and feeding the loads with the rest ones,

either during the preventive maintenance period or the

self-reparation.

Therefore it has been considered appropriate and naturally,

to contemplate in the instructions of the equipment, the

operation of a system with «n» equipment connected in

parallel with their respective external manual bypass

panel board as it is shown in the «Recommended installation» documentation included in the CD.

This panel board allows isolating each equipment individually in case of fault and removing it without any difficulty for its reparation or replacement. Also, the included manual bypass switch makes it easier to do the preventive maintenance tasks or intervention over the complete system, supplying the

voltage to the loads directly from mains, on the «bypass»

mode operation, mean- while the input voltage is available.

In those installations without the external manual bypass panel board, omit the actions and steps that involve the maneuvering of their switches.

Fig.33. Procedure start-up / shutdown.

6.1. PRELIMINARY CONSIDERATIONS.

• It is very important to always operate in the established order in the described instructions in the next sections, by respecting the sequence of the switches in relation to its function.

So, i.e. in parallel system based on four equipment, when it is

stated to turn on the «Input» mechanisms, the order of turning

on them will not matter, but any other switch with different

function as it could be «Output» switch will not be turned on,

till is stated.

• Unlike other UPS structures, where the «Master» and «Slave»

equipment are preset strictly from factory, conditioning the

order of start-up and shutdown, the new UPS series is managed by a more flexible hierarchy according to the operating mode that it is.

6.2. START UP

6.2.1. Control before start up

˙ Carefully make sure that all the connections have been made

correctly and are sufficiently tight, respecting the labelling of the device and the instructions of chapter «4.- Installation and wiring of the unit».

˙ Check that the UPS switches and the batteries cabinet or

cabinets are turned off (position «Off»).

˙ Be sure that all the loads are turned «Off».

˙If the UPS connects to external battery cabinet, set the fuse holder

switch of the battery cabinet (Q8) to «On».

˙If the power supply you use to supply the UPS has a general switch.

Set the general switch of the header board to «On».

˙Turn the input switch (Q1a) to «On» position. The Display of the

Control Panel (PC) will be turned on automatically.

˙ If the following alarm message appears on the Control Panel

Display,

.. and also an audible alarm comes on, the UPS cannot be started, because of incorrect input phase sequence. Disconnect the input switch (Q1a) and the general cut-off of the header board, swap the phases of the input terminals of the UPS according to the labelling and repeat the start-up process described up to now.

˙In units with separate Bypass (UPS-B), also turn the Bypass switch

(Q4) to «On» position.

˙If the following alarm message appears on the Control Panel

Display,

... and also an audible alarm comes on, the UPS cannot be started, because of incorrect input phase sequence. Disconnect the Bypass switch (Q4) and the general cut-off of the header board, swap the phases of the input bypass terminals of the UPS according to the labelling and repeat the start-up process described up to now.

Start up the inverter through the keypad of the control panel.

a. Select ”CNTL” b. Select ”ON/OFF” c. Start up unit information will appear. Select ”Yes”.

Then, the inverter and rectifier will start. ˙Once the rectifier is completely working, it starts a process of

equalization (DC bus voltage starts to equalize with battery voltage). After a few seconds (depending on the battery level), an alarm message appears like this.

…it displays that the equalising process has been finished, and

IN THIS MOMENT ONLY is when the battery fuse holder switch or switch of UPS (Q3) can be turned on.

DO NOT TRY to close any battery fuse holder switch at any other moment, because this operation could damage the equipment and/or cause possible accidents. They can only be turned on by following the quoted previous steps.

Turn on the output switch (Q2) to “On” position. The system will supply voltage at the output terminal.

If you want to start up a parallel system, you should follow the steps

below.

Close the mains circuit breaker to provide power to the input of the each UPS in the system. Turn the input switch (Q1a) to “On” position for each UPS in the system. Each display of the Control Panel will be turned on automatically. Do not close any other switches at this time. Repeat the start-up process on LCD Touch Screen as what mentioned before.

• After 30 seconds, the inverters and rectifiers of each UPS will start up, but they will not supply voltage at their output yet because the output switches are not turned on yet.

The first UPS to start up the inverter will be set as «Paral. Mst. Byp» initially, the one with the highest address as «Paral. Slv. By.Rsv» and the rest, if there are any as «Paral. Slv. By». Obviously in those systems with two equipment, the «Paral. Slv. By» will not exist. The UPS hierarchy relating to the rest of equipment of the system is a dynamic depending on the status of the rest of the equipment.

To check the hierarchy of the UPSs (parallel status), is needed to go back to main screen in each equipment marked in the picture below (Screen 00):

Where: –– «Paral. Mst. Byp» Bypass master of the parallel system. By default, it is the first UPS that starts up the inverter by the previous established procedure.

–– «Paral. Slv. By.Rsv» Reserved bypass slave. Initially corresponds to the equipment with the highest address less the one with «Bypass Master». In case of fault in the Master, it will take its functions.

–– «Paral. Slv. Byp» Bypass slave of parallel system (for systems with more than two equipment only). It will become as «Reserved bypass Slave», when it works as «Bypass Master». In those systems with more than three equipment in parallel, the hierarchy of «Reserved bypass Slave» will be taken by the highest address among the «Bypass Slave».

–– «Paral. Mst. Volt» Voltage Master of parallel system. By default, it is the first UPS running on normal mode (inverter in operation) that the output switch (Q2) is turned «On».

–– «Paral. Slv. Vt.Rsv» Reserved voltage slave of parallel system. Equipment on normal mode (inverter in operation), that the output switch (Q2) has been turned «On» in 2nd place or subsequently (after «Paral. Mst. Volt» or «Paral. Mst. Vt.Rsv»). Initially, it corresponds to the equipment with the highest address less that one with «Voltage Master». In case of fault in the Master it will take its functions.

–– «Paral. Slv. Volt» Voltage Slave of parallel system (systems with more than two equipment only). Equipment on normal mode (inverter

in operation), that the output switch (Q2) is turned «On» in 2nd place or subsequently (after the «Paral. Mst. Volt» or «Paral. Mst. Vt.Rsv»). It will become as «Reserved voltage slave», when it works as «Voltage Master». In those systems with more than three equipment in parallel, the hierarchy of «Reserved voltage slave» will be taken by the highest address between the «Voltage slave».

• Make sure that the inverter voltage is same, e.g.: 230Vac

• Turn all output switches from panel «On».

• Turn the output switch (Q2) of each UPS «On».

The system will supply voltage at the output terminals of the protection panel.

˙If the system has outgoing distribution protections, switch them «On».

˙Start up the loads to be supplied in a progressive way. The system is started up completely, and the loads are protected through

the UPS.

• With the system running (switches turned «On»), when shutdown or start up the inverter through the keypad of any UPS that belongs to it, all of them will be turned «Off» or «On». In both cases, the UPSs still supply output voltage at «On» position through the inverters and «Off» position through the static bypass.

6.2.2.1 Take into consideration about Master and Slave

• Bypass Master and Slave («Mst. Byp.», «Slv. Byp.», «Slv. By.Rsv»).

■ Master manages the status of its own static bypass switch and the one of the Slave equipment.

■ Equipment that are not sharing the load by the inverters. The cause can be any of the following:

– Output switch (Q2) turned «Off». – Equipment output on bypass. – Inverters are shutdown or in start up process.

• Voltage Master and Slave («Mst. Volt», «Slv. Volt», «Slv. Vt.Rsv»).

■ Master manages both the status of its own static bypass switch and the inverter voltage, as well as the one of the Slave equipment.

■ Equipment are sharing the load on inverter. Therefore:

– Output switches (Q2) are turned «On». – Inverters are running and static switches are on inverter.

6.3 SHUTDOWN OF ONE EQUIPMENT FROM THE PARALLEL SYSTEM

• Turn the output switch (Q2) of the UPS to shutdown «Off». In the screen 0.0 from LCD panel will display:

6.4 START UP THE PREVIOUS UPS AGAIN

• Start up the inverter by means of the keypad from control panel.

• Turn the output switch (Q2) of the UPS «On».

6.5. COMPLETE SHUTDOWN OF THE UPS

˙Shutdown the loads.

˙If the system has outgoing distribution protections, switch them

«Off».

˙Shutdown the inverter. Please go to «CNTL» submenu (Screen 1.0),

and select «OFF». You will get Screen 1.2, asking you to shut down the unit, by selecting (YES) to shut down the inverter.

˙Turn the output switch (Q2) to «Off» position.

˙In standard units, set the input switch (Q1a) to «Off» position. In B

units, set the input switch (Q1a) and static bypass switch (Q4) to «Off» position.

˙Turn fuse holder switch from battery cabinet (Q8) and/or battery

fuse holder switch or switch from UPS (Q3), to «Off».

˙Cut the power supply of the UPS and the bypass with the cut-off or

general switch of the header board. The system will be completely deactivated.

˙ Electrical discharge hazard. If after shutdown of the equipment,

it is required to disconnect the separate battery pack/s, wait several minutes (5 min. approx..), till the electronic capacitors have been discharged.

˙The equipment is completely shut down.

6.6. EMERGENCY POWER OFF (EPO) OPEARTION

Emergency Power Off (EPO) is equivalent to a complete unit system halt:

˙All UPS converters are turned off (rectifier and inverter off). ˙No output voltage is supplied to the loads.

See table below for operation:

E.P.O. function

Activation

(perform System Halt)

Return to

normal-mode.

Terminals (X50). Normally closed circuit by means of the provided cable bridge (it allows an external switch (EPO)).

Remote button or switch has to be opened permanently in terminal strip (X50).

The equipment has to be shut down and deenergized completely (turn off all switches), wait till DC bus is discharged (LCD has to be turned off). The equipment has to be started up according to section

“5.1.2. Start up procedure”.

Table.4. Emergency Power Off (EPO) operation Emergency shutdown function (EPO) can only be activated through the terminal strip (X50). In a parallel system, it is not needed to make additional connections than there is just only one equipment, because through the communication BUS, any action over the button will affect to the joint of the parallel system.

6.7. BYPASS MANUAL SWITCH (MAINTENANCE).

6.7.1. Principle of operation.

The integrated manual bypass of the UPS is a very useful element, but

Not connected

Screen 0.0

undue use can have irreversible consequences both for the UPS and for the loads connected to its output. It is therefore important to handle it as described in the following paragraphs.

6.7.2. Transfer to maintenance bypass.

Procedure for passing from normal operation to maintenance bypass:

˙Shutdown the inverter. Through the LCD touch panel, go to «CNTL»

submenu (Screen 1.0), and select «OFF». You will get Screen 1.2, asking you to shut down the unit, by selecting (YES) to shut down the inverter.

˙Remove the screws to that fixes the mechanical block (BL).

˙Remove the mechanical block (BL) of the manual bypass switch

(Q5) and set it to «On» position.

˙Set the output switch (Q2) to «Off» position.

˙Set the Battery Fuse Holder or battery switch (Q3) to «Off».

Besides, in models with independent battery pack/s also turn Battery Fuse Holder (Q8) of each pack to «Off».

˙In standard units, set the input switch (Q1a) to «Off» position.

In UPS-B units, set the input switch (Q1a) and static bypass switch (Q4) to «Off» position.

The UPS is supplying output voltage directly from the mains through the manual bypass in units or from the mains of the static line bypass in the version UPS-B units, through the manual bypass. The UPS is completely shut down and inactive.

6.7.3. Transfer to normal operation.

Procedure for switching from maintenance bypass to normal operation:

˙In model with external battery cabinet, set fuse holder switch from

battery cabinet (Q8) to «On» position.

˙In standard units, set the input switch (Q1a) to «On» position.

In B units, set the input switch (Q1a) and static bypass switch (Q4) to «On» position.

˙Set the output switch (Q2) to «On» position.

˙Set the manual bypass switch (Q5) to «Off» position and refit the

mechanical block (BL) and the screws (t2).

It is an essential requirement for safety to refit the mechanical

block (BL), as this avoids dangerous handling for the life of the UPS and the loads connected to it.

˙Start up the inverter. The start-up operation will be done through

the LCD touch panel. Select «CNTL» to get into control submenu (screen 1.0), and then select «ON/OFF». You will get to screen 1.1, asking you to start the unit up yes or not. You can select Yes. See screen diagram (Fig. 33).

The UPS supplies output voltage entirely protected against voltage variations, electric noise, etc.

˙Wait for alarm message to appear as:

˙Battery fuse holder switch or switch from UPS (Q3) can only be

turned «On» when the previous alarm message has been cancelled.

˙The UPS supplies output voltage entirely protected against cuts,

micro cuts, voltage variations, electric noise, etc.

8. MAINTENANCE, WARRANTY AND SERVICE.

8.1. BASIC MAINTENANCE GUIDE.

Batteries, fans and capacitors must be replaced at the end of their useful lifetime.

Inside the UPS there are dangerous voltages and metalli

parts at very high temperatures, although the UPS is shutdown. The direct contact can cause electrocutions and burns. All the operating, less the battery fuse replacing, must be done by authorized technical staff.

Some internal parts of the UPS (terminals, EMC filters an

measurement circuits) are still under voltage during th

e maintenance bypass operating. To cancel all the voltages, the c

ircuit breakers of mains and bypass of the panel board that feeds the UPS and the fuse holders of the battery rack have to be

turned «OFF» / «0».

8.1.1. Battery fuses.

Turning on the battery switch and/or fuse holder «ON» or «I» position, and only after displaying the alarm message «B AT T. SWITCH OPEN, SWITCH IT ON» in the LCD panel.

The battery fuses can only be replaced by ultrafast fu

models type aR 660V, of the same size and current used in

the equipment and/or battery module.

8.1.2. Batteries.

The useful lifetime of the batteries depends on the ambient temperature and other factors like the quantity of charging and discharging cycles and the deep discharges done.

The average lifetime is between 3 and 7 years if the ambient temperature is between 10 and 20ºC. To have more information of its status, activate the battery test.

Risk of fire and/or explosion exists if a wrong quantity or

type of batteries is used. Do not dispose the batteries to the fire: they can explode. Do not open and mutilate the batteries: the dumped electrolyte is dangerous for the skin and eyes. It can be toxic.

8.1.3. Fans.

The useful lifetime of the used fans to cool the power circuits depends on the use and environment conditions. It is recommended their preventive replacement by authorized technical staff.

8.1.4. Capacitors.

The useful lifetime of the DC bus capacitors and those ones used in the input and output filtering depends on the use and the environment conditions. It is recommended their preventive replacement by authorized technical staff.

8.2. WARRANT Y CONDITIONS.

The limited warranty only applies to those products that you acquire for commercial or industrial use in the normal development of your business.

8.2.1. Covered Product.

9.2. GLOSSARY.

• AC.- It is nominated as alternating current to the electrical current in which the magnitude and direction varies in a cyclic way. The most common wave shape of the alternating current is sinewave, because the energy transmission is better. Neverthe- less, some applications could need other period wave shapes, like triangular or square.

• Bypass.- Manual or automatic, it is the physical junction between the input and the output electric device.

• DC.- The direct current is the continuous electron flow through a cable between two points with different potential. Unlike the alternating current, in direct current the electrical loads always flow in the same direction from the highest potential point to the lowest one. Although, usually the direct current is identified with the con- stant current (for example the one supplied by the battery), it is continuous any current that always maintain the polarity.

• DSP.- It is the acronym of Digital Signal Processor.A DSP is a system based on a processor or microprocessor that has instructions in it, a hardware and an optimized software to develop applications where numerical operations are needed with very fast speed. Due to this, it is very useful to process ana- logical signals in real time: in a system that runs in this way (real time) samples are received, usually coming from an analogical/ digital converter(ADC).

• Power factor.- It is defined as power factor, p.f., of an alternating current circuit, as the ratio between the active power, P, and the apparent power, S, or as the cosines of the angle that make the current and voltage vectors, designating as cos , being j the value of that angle.

• GND.- The term ground, as its name states, refers to the potential of the earth surface.

• IGBT.- The Insulated Gate Bipolar Transistor is a semiconductor device that is used as a controlled switch in power electronic circuits. This device has the feature of the gate signal of the effect field transistors with the capacity of high current and low voltage saturation of the bipolar transistor, combining an isolated FET gate for the input and a bipolar transistor as switch in a single device. The triggering circuit of the IGBT is as the MOSFET one, while the driving features are like the BJT.

• Interface.- In electronic, telecommunications and hardware, an interface (electronic) is the port (physical circuit) through which are sent or received signals from a system or subsystems toward others.

•

kVA.-

The

voltampere

is the unit of the

apparent power

in electrical current. In direct current is almost equal to the real power but in alternating current can defer depending on the power factor.

• LCD.- LCD acronym of Liquid Crystal Display, device invented by Jack Janning, who was employee of NCR. It is an electric system of data presentation based on 2 transparent conductor layers and in the middle a special crystal liquid that have the capacity to orientate the light when trespassing.

• LED.- LED acronym of Light Emitting Diode, is a semiconductor device (diode) that emits light almost monochrome with a very narrow spectrum, it means, when it is direct polarized and it is crossed by an electric current. The color, (wave longitude), depends on the semiconductor material used in its construction, being able to vary from the ultraviolet one, going through the

visible spectrum light, to the infrared, receiving these last ones the denomination of IRED (Infra Red Emitting Diode).

• Circuit breaker.- A circuit breaker or switch, is a device ready to break the electrical current of a circuit when it overcomes the maximum set values.

• On-Line mode.- Regarding to an equipment, it is on line when it is connected to the system, and it is in operation, and usually has its power supply turned on.

• Inverter.- An inverter, is a circuit used to convert direct current into alternating current. The function of an inverter is to change an input voltage of direct current into a symmetrical output voltage of alternating current, with the required magnitude and frequency by the user or the designer.

• Rectifier.- In electronic, a rectifier is the element or circuit that allows to convert the alternating current into direct current. This is done by rectifier diodes, which can be solid state semiconductors, vacuum or gassy valves as the mercury vapour. Depending on the features of the alternating current power supply used, it is classified as single phase, when they are fed by a single phase electrical mains, or three phase when they are fed by the three phases. Depending on the rectification type, they can be half wave, when only one of the current semicycles is used, or full wave, where both semi-cycles are used.

• Relay.- The relay(in French relais, relief) is an electromechanical device that works as a switch controlled by an electric circuit where, through an electromagnet, a set of contacts are moved and it allows to open or to close other independent electric circuit.
