2.2. SAFET Y INSTRUCTIONS.
•
Check the data
of
the nameplate are the required
by
the installatio
n.
• Never forget 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 lies in the batteries, a part from AC mains,
which can be included or not in the same case or cabinet of the
electronic parts of the equipment depending on the model and/
or extended autonomies.
When the
equipment
is ON, if
batteries
are
connected
to the
equipment and it protections, if any, are turned “On”, the fact that
the UPS is connected or not to mains is irrelevant, as well as the
status of the own protections of mains. The outlets or output
terminals will supply voltage meanwhile 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 consults 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 risk on your or on the other/s 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 different
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 it can be used by personnel with
no specific training, just only 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 he has the requirements to do the job and if 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 has to be placed in all primary switches, installed in
areas far way 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 in all terminals, including the
earth
main protective earth.
Risk of UPS backfeed voltage.

• To manipulate over the connection 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. To keep in mind.
• The UPS is supplied packaged from factory in the best way for
its transport and shipment till its new owner or receiver. It is
recommended to transport it packaged as close as possible to
its final location.
• When serious damages are observed in the packaging, and due
to its level of deterioration damages can be sensed in the
contents and/or the shock indicator is in RED, proceed
according to the instructions stated in the own label of
transport control.
Keep the affected equipment isolated from other received
equipments, waiting the pending inspection by qualified staff.
In case it were needed to return it back to the factory or your
distributor and it were not possible to use the same packaging
due to the poor conditions of itself, 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 work of at least two persons.
• The equipment has to be in vertical position always.
When moving the equipment, consider the slope of the
ground or surface and the risk of tipping.
• Be careful to not lift heavy loads without help, according to the
following recommendations:
, < 18 kg.
, 18 - 32 kg.
, 32 - 55 kg.
, > 55 kg.
• In case of an accidental equipment dropping or if the
enclosure is damaged, 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 equipments shall be guided by two persons as minimum,
which will be placed on either side and oriented to the walking
direction.
• UPSs are electronic equipments. Avoid jolting or bouncing like
those produced by moving the equipment over an uneven or
wavy surface.
• When moving an equipment from a cold place to a warm
environment and vice versa, it can cause condensation (small
water drops) in the external and internal surfaces. Before
installing a moved equipment from another place or even
packaged, the equipment will be left for a minimum time of
two hours in the new location before making any action, with
the purpose of adapting it to the new environmental conditions
and avoid the 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, warms, dusty or with conductive parts environments and
never outdoors.
Installation location will be cooled, dry and far from heat
sources and with easy access. If possible in an environment
with temperature control.
• Avoid to locate, install or store the equipment in places with
direct sunlight or high temperatures. Batteries can be damaged
and/or make shorter its useful lifetime.
In the exceptional and long exposition case to 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 entering objects through
themselves or other orifices.
• Locate the equipment as close as to the power supply outlet
and loads to supply, leaving an easy access if it were needed an
urgent disconnection.
• All models with casters have four leveller parts -feet-, which are
located at each corner of the base, with the purpose of locking
and level the unit.
Loosen them with the hand until they stop with the ground.
With the help of a spanner, act on each one and loosen
them half round more against the ground.
In grounds slightly uneven, level the equipment by means of
these leveller parts.
Check that the equipment is completely immobilized.
Fortuitous pulls of the connection cables of the equipment
will indirectly be avoided, because unexpected movements
will not happen.
• Even though the interventions inside of the equipment, battery
cabinet and battery manipulation is a task reserved to
personnel with specific or qualified knowledge only and in
par- ticular to (S.S.T.), it is mandatory to immobilize the
equipment by means of the levellers parts -feet- stated in the
previous point, before doing any action.
Attention! Risk of tipping when removing the battery
trays without stabilising the unit first.
Do not remove more than one tray together, high risk of injury
over the operators due to shock of the possible equipment fall
down and/or entrapment.
• Leave a minimum free space to cool the unit of:
25 cm at both sides.
50 cm at the rear side.
100 cm at the top side.
and 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 needed
clearance of the connection cables to facilitate the forward
movement of the equipment.
• Do not cut, deteriorate or manipulate the electrical cables,
neither put heavy objects over them. Any of these actions
could cause a short-circuit and make a fire or electrical
discharge.
Check that the electrical cables of connection, plugs and outlets
are in good conditions.

• All power supply electrical cables have to be fixed to the
equipments and loads, interfaces, etc..., to immovable parts
and in the way to avoid step on it or go through them with an
transport medium or expose them to fortuitous pulls.
• Be careful to not wet it, because it is not waterproofed. Do not
allow entering any kind of liquids in, otherwise shutdown it
immediately and contact with the (S.T.S.).
• If the enclosure of the equipment is in contact with liquids or
high density saline air accidentally, dry it with a soft and
absorbent cloth quickly.
Check that no liquid has entered inside the unit and act
accordingly.
• To clean the equipment, wipe over a 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 equipments with products that could have
alcohol, benzene, solvent or other inflammable substances, and
even if they are abrasive, corrosive, liquids or detergent.
• Never manipulate the equipment with wet hands.
• If it is observed that the UPS exhausts smoke or toxic gas,
shutdown it immediately and disconnect it from power supply.
This kind of fault can cause fire or electrical discharge. Contact
with our (S.T.S.).
• Do not put either materials or parts over the equipment that
obstruct the correct visualization of the synoptic.
• 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 a minimum period
of time of 12 hours.
Although the equipment can operate with batteries discharged,
it has to be kept in mind the possible risk of mains fault during
the first operating hours, so the available back up time in the
UPS batteries, can be lower than the expected.
2.2.2. General safety warnings.
• All electrical connections and disconnections of cables from
the equipment, including the control ones, will be done with no
power supply and switches on rest position «O» or «Off».
• Pay special attention to the labelling of the equipment
that warns about the «Electrical shock hazard», inside
the equipment there are dangerous voltages.
Do not open, dismantle or modify the equipment, if this action
is not stated in this document. To manipulate inside the
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 that
make the modification, internal or external of the equipment
or just only the simple intervention inside of itself, which is not
stated in this document, it can expire the warranty.
• During the erection and commissioning operations is needed to
open the front door and some models is required to remove the
protection cover from terminals too.
Once the respective actions are finalised, leave the equipment as
it was, with the protection cover put back and front door closed.
• To shutdown 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 equipments.
• Protection Earth cable of the UPS drives the leakage current
of the load devices. An isolated earth cable has to be
in
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 colour with or without the 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 that feed the loads have their respective
protection earth cable.
When branch circuits are made, 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, it has to be between
the defined parameters by the local or national regulations.
• During the normal UPS operation, the input power supply
cable can’t be disconnected, because the general protection earth
cable of the own UPS and all loads connected at the output will
be disconnected too.
Due to the same reason, the general protection earth cable of
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,
w
ill be
according to
the nominal current stated in the nameplate l
abe
l of
the equipment, and respecting the Low Voltage Electrotechnical
Regu
lations
or
standards
of the country.
• UPS equipments 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.
For the correct operation of the UPS, it is needed the input
Neutral cable or in case of its missing, it has to be created by
means of an isolation transformer located between the power
supply and the equipment.
• The UPS doesn’t modify 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 any of both input lines
(rectifier input or static bypass), in order to avoid the direct
connection of the neutral of 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, ...
• La The installation will have input protections sized to the
currents of the equipment and stated in the nameplate label
Page 8
5
(RCD devices type B and circuit breakers with C characteristic
or any other equivalent one).
For equipments with three phase input, and connected to an IT
distribution system, the protection will be four poles in order to
break the three phases and neutral in the same manoeuvring.
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 equipments 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
as 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 that any fault in any device
connected to the equipment, that makes a short-circuit, will
affect 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 direc
tly or
through other
outlets.
• When supplying input voltage to a UPS with static
bypass or separate bypass line, the fact of having the inverter
«Off» (shutdown), it doesn’t mean to not have voltage at the
output terminals.
To not have it, 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 equipments that incorporate it either
standard or optional, so it will have to be considered as regards to
safety.
If it were necessary to break the output supply of the equipment in
this situation, turn off the outgoing distribution protection or in lack of
it, turn off the general protection of the distribution panel that feeds
the UPS.
• All the equipments have two auxiliary terminals to install an
external emergency power off button (EPO), which will belong
to the end-user.
EPO doesn’t affect to the power supply of the equipment, it only
breaks the power supply to the loads as a safety measure.
• RACK mounted equipments are destined to be installed in a
predeter
mined se
t to
be done b
y professionals.
Its installation has to be designed and executed by qualified
personnel, who will be the responsible to apply the safety
and EMC regulations and standards that controls the
particular installations 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.
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 that there is not 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 equipments with separate battery cabinet, check that they
are compatible before connecting them.
• When faulty batteries are replaced, the complete battery set
has to be replaced, less exceptional cases in new equipments,
were due to manufacturing faults it will only be replaced the
defective ones.
The replacement will be done by another one of the same type,
voltage, capacity and quantity. All of them has to be of the
same brand. Otherwise there is risk of explosion.
• Do not reuse faulty batteries. There could be an explosion or
burst any battery with the involved problems and issues that
could happen.
• 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 equipments requested without batteries, their
acquisition, installation and connection of themselves will be
done by the end-user and under his responsibility. Data
concerning the batteries as regards to quantity, capacity and
voltage, are stated in the battery label sticked beside the
nameplate of the equipment. Respect these data, battery
connection polarity and the supplied circuit diagram strictly.
For an optimum and efficient operating, the battery set has to
be located as close as possible to the equipment.
• Battery voltage can involve the risk of electric shock and
can produce high short circuit 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, ...
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
cable’s polarity and color (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 due to the
accumulated hydrogen.
Metallic particles of different sizes can be thrown due to
the violent explosion of the short-circuit and/or the tool
itself or the metallic object, which origin the incident, with
the risk of significant damage to nearby people and other
devices, instruments or machines.
Never manipulate them with your hands or through
con
ducting objects, do not short either the battery terminal

• In case the automatic software to shutdown the devices due to end
of back up time is not installed, it is recommended to shutdown 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 operating during the night, weekends and
holidays periods, it is recommended to shutdown the equipment
completely. In particular during this last period and due to safety
reasons, as it is an energy generator, and to safeguard batteries
against unnecessary discharges during these periods of time.
• When the equipment and/or battery module has a protection by
fuse and it were needed to replace it, do it by another one of the
same type, format and size.
• After prolonged periods of time of disconnection, it is
needed to recharge the batteries for 12 hours as
minimum every 6 months, in order to avoid the irreversible
degradation of them.
• Never short the battery terminals due to the high risk that involves. It
involves
the detriment of 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.
• In case of contact of the acid with parts of the body, wash
immediately with plenty water and call urgently to the
nearest medical service.
• Batteries involve a serious risk for health and environment. Their
disposal should be done in accordance with the existing
regulations.

4. PRESENTATION.
4.1. VIEWS.
4.1.1. Views of the equipment.
Figures from 1 to 20 show the illustrations of the equipments
according to model, nominal operating voltage and input-output
setting, which is summarised in the 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 and as the product is in constant evolution, some
discrepancies or small contradictions can arise. So, if any questions,
the labels over the own 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 for
«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 than matching
and/or helping in order 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 equipments of the same family, because the needed
electronic kit is already included.
Parallel connection 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 equipments of different features versions,
settings, back up times or duplicated addresses (i.e.: two
equipments, 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 equipments 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, which its function is to
attenuate and cancel all the radio frequency perturbations. The
filter performs in a bidirectional way:
• It cancels the perturbations that comes from the line and protect the UPS control circuits.
• It avoids the possible radio electrical perturbations that the
UPS could generates flows through the line and affect to other
equipments 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 efficiency.
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 efficiency. 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: it is used an identical solution as the used
at 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 inverter-bypass 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 manoeuvring of the maintenance bypass is “make
before break”, with the purpose of keeping the critical loads fed,
even during the maintenance tasks.
Page 27

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 about the current status of the equipment
and electrical measurements to the end-user. It is based on a tree
menu, 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
cur- rent of the active rectifier.
It is important to highlight that the different controls of the UPS
do not operate either isolated or locally, but they interact between
them in such way that it results a global 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 been also 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
against the load transients.
In normal conditions, the rectifier is running and charging the
batteries, controlling at any moment the charging current and
floating voltage according to the temperature of themselves.
The system is also in charge of minimising the charging current
ripple that flows through them.
When the input voltage or frequency is out of the correct
operating range, it is shutdown and batteries are responsible of
keeping the inverter in operation, which at the same time
supplies the loads connected at the output of the equipment till
the battery voltage decreases till the end of back up time.
Another important feature of the rectifier is its bidirectional
capacity of operation. This allows consigning a battery
discharging current even with mains present. This quality
performance will make possible to do a battery test both in full
load and no load conditions.
• Output three phase rectifier controller: independent per
phase, it is easy adapted to different settings, either single
phase or three phase.
It is highlighted the use of the AFC control technique that
allows getting an output voltage with a THDv lower than 1,5%
with non-linear 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 possible the dialogue between the
equipment and other machines or devices.
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 teh 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 shutdown the
inverter.
The most common use of this type of port is to supply the
needed 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 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 to the system
high immunity to 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,
Page 28
25
etc...). Whatever the type of load to protect is, these equipments
are 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 equipments, by improving a
lot important coefficients like the power/footprint ratio.
• Basically its operating is the following:
The rectifier, an IGBT three phase rectifier, converts 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
into AC providing an alternating sinewave output, stabilised
in 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
by
pass 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
providing an alternating sinewave output, it stabilises the voltage
and frequency, ready to supply the loads connected at the output
(Fig. 25 and 26).
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 in the capacity of the battery
set only (Fig. 25 and 26).
When the battery voltage reaches the low voltage, the control
blocks the output in order to protect the batteries from being deep
discharged. When mains is restored and after the first seconds of
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. 25 and
26), on 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 it to 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 later on stated).
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, allows the equipment feeding the loads directly
from mains through the solid state static bypass («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 efficiencies between 4 and 4.5 %
highest than «On Line» normal mode, so it is close to 100 %.
The «Smart Eco-mode» operating 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, in case it were needed, according to section 7.3.2. and
Fig. 45.
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 equipments set as frequency converters, the static bypass and
manual bypass are not available.
So, those functions, measurements, alarm messages, parameter
settings, as well as manoeuvring 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 s e r i e s , are
designed and thought for its «parallel» connection with a maximum
of four units, on condition that they are the same model (setting,
voltage, power, frequency, back-up time, ...), all of them without
adding hardware. Fig. 27 and 28, as an example, 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 in 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
equipments 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 them 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
that the damaged 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 an AC power supply of quality for the most critical
loads.
The quantity of redundant equipments to be connected has to
be studied according to the requirements of the application.
Parallel connection, redundant or not, adds several advantages
a part from the connection itself:
• Higher punctual power and back up time: in a parallel
system of N+M equipments, it is considered the nominal
maximum load of N equipments and +M are the reserve ones,
so:
N, is the quantity of equipments in parallel,
corresponding
to
the minimum quantity required by the total needed power.
+M, is the additional quantity of equipments corresponding
to the residual safety power (redundant equipments).
Although, in practice it can drain the total power in that 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 equipments, 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 equipments of the same feature, without needing to
replace the equipments 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 equipments.
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
synchronisation, ...; are managed by the MASTER equipment, and
transmitted to the SLAVES equipments through the management
bus of the parallel system.
This MASTER or SLAVE condition is dynamic as it is described later
and it will depend on several factors (initial status of the
equipments, chronological order of commissioning or shutdown of
the system through one equipment or other one, ...)

5.1.4.1. Location for single equipments.
• As i.e. Fig. 29 shows two typical cases depending on the m
ode
l.
The one that is based on a single cabinet, UPS with batteries
fitted in, and the one of the UPS with batteries in a separate
cabinet or extended back up time.
For extended back up times with more than one cabinet, it is
recommended to put one at each side of the equipment and in
case of having more cabinets repeat the same sequence alternately.
As minimum, leave a free space for cooling the unit of:
- 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 easier its
movement towards.
Fig. 29. Floor view with minimum distances for a UPS.
5.1.4.2. Location for parallel systems.
• As i.e. Fig. 30 shows 4 UPSs in parallel with their respective
battery cabinet. For systems with less units act in each case
accordingly.
• It is advisable to put them in order by the No stated in the door
of each equipment. The number corresponds to the assigned
address preset from factory.
The arrangement is not random, because the length of battery
wires (3.5 m.) and communication BUS (5 m.), this is the best
one. For a higher quantity of battery cabinets in systems with
extended back up time, follow the same criteria keeping the
symmetry.
• When the system is structured by models with batteries and
power electronics in the same cabinet, forget the battery
modules illustrations.
Always respect the distances stated in Fig. 30, a part from the
quantity of cabinets that sets the system.

5.1.4.3. Equipment immobilized and levelled.
• All UPSs and battery modules, which have casters, have 4
stabiliser elements (PB), arranged next to each caster.
• The purpose of the stabilisers elements (PB) is lay, immobilize
and level the metallic cabinet once it has been located, in order
to avoid possible overturns, in particular those ones that battery
shelves can be extracted.
Warning! Turnover danger when extracting the battery
shelves without stabilising the unit previously. Do not
extract more than one shelf at the same time, high risk
of causing serious injuries to the operators due to the
impact of the possible fall and/or trapping of the
equipment.
• Loosen the elements (PB) by hand turning them
counterclockwise as far it would go with the floor and with the
help of a spanner, loosen them half turn more in order to
immobilize the metallic cabinet, having a correct levelling.
Fig. 31 shows how the stabilizers elements (PB) have to be
finally.
• 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
manoeuvring
that are only available in some versions
or equipments with extended back up time. Ignore those
operations regarding them, 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 ad
visable
having a switchgear panel board and for systems with 3 or
4 equipments, it is essential. Switches of the panel board
have to allow isolating the UPS from the system against any
wrong operating and feed the loads with the rest ones,
either during the preventive maintenance period or the
reparation of itself.
• Under 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

protection size and
minimum
cross section o
f the wires that are connected to
Fig. 31. Equipment / battery module stabilisers 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 would need and
intervention, it is essential to pay attention and respect the
indications of the label sticked in each shelf, before
extracting them (see Fig. 31).
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.
For longer lengths correct the cross sections accordingly, in
order to avoid dropping voltages, by respecting the Regulations
or norms corresponding to the country.
In manual and for each setting, the information is available
Page 34
31
for «N» units in parallel, as well as the features of the own
«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 own 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 the EN-IEC 62040-1 safety standard. The input current
calculation, has been done taking 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
respecting 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 were required, remove this bridge, by taking the
precautionary measures stated in the respective local and/or
national low voltage regulations.
• To enter 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 equipments 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 of a plastic bag
together 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, preset from factory is
opened.
– +
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, 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 manoeuvre the battery fuse holder an
d/or switc
h
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 beyond of a simple intervention and it is planned to
have them out of service for long time, proceed to 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 the cabinet for its connection.
• Any equipment and battery cabinet from this series has
terminals as connection elements for the power. Also UPSs have
a terminal strip for the auxiliary connections and HDB9 / DB9
communication connectors.
To have access to them proceed as follows and repeat the same
procedure in each unit for parallel systems:
Unblock the lock/s (CL) by means of the key (LL) supplied
with the equipment, turn it to clockwise 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 remove it; 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 embrace
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 T T, TN-S, TN-C or IT, taking
into account when installing the particularities of the used
system and the national electrical regulation of the destination
country.
5.2.1. Connection to mains, terminals (X1 to X4).
• As this is an equipment with class I protection against
electrical
shocks,
it is
essential
to install the
protection
earth
conductor (connect earth ( )). Connect this conductor to
terminal (X5), before supplying voltage to the input terminals.
• Equipments without static Bypass line, in accordance with the
safety standard EN-IEC 62040-1, installation has to be provided
with a «Backfeed protection» system, as for example a
contactor, which will prevent the appearance of dangerous
voltage or energy in the UPS input mains during a mains fault.
The standard is applicable both if power supply is single phase or
three phase and for single units, and for each UPS of the parallel
system.
• If it’s required more detailed information for particular
system configuration, ask for the relating «Recommended
installation» information. In that information is shown the
circuit dia
gram, as we
ll as the
protection size and
minimum
cross section o
f 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.
For longer lengths correct the cross sections accordingly, in
order to avoid dropping voltages, by respecting the Regulations
or norms corresponding to the country.
In the own documentation and for each setting, it is available
the information for «N» units in parallel, as well as the features
of the own «Backfeed protection».
• There can be no derivation in the line that goes from th
e
«Backfeed protection» to the UPS, as the safety standard
would be infringed.
• Warning labels should be placed on all primary power switches
installed in locations away from the equipment to alert the
electrical maintenance staff of the presence of a UPS in the
circuit.
The label will bear the following or an equivalent text:
Before working on this

• Connect the input cables to the respective terminals according
to the available equipment setting.
For parallel systems, it will be necessary to repeat the
connections that go from panel board to each equipment.
Connection to three phase mains:
Connect the power supply cables R-S-T-N to the input terminals
(X1), (X2), (X3) and (X4), respecting the phase rotation
and neutral indicated on the label of the equipment and in this
manual. If the phase rotation is not respected, the equipment
will not operate.
In case of discrepancies between the label and the instructions
of this manual, the label will always prevail.
Connection to single phase mains:
Connect the power supply cables R-N to the input terminals (X1)
and (X4), respecting the order of phase and neutral
indicated on the label of the equipment and in this manual. If the

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.

• 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).

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.

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

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
equipments of the parallel system.
By means of the own communication BUS among the
equipments 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.

5.2.9. Auxiliary contact and battery temperature probe
terminal strip.
• All the equipments are provided with terminal strip that
corresponds to the auxiliary contacts of manual bypass (X51)
and output (X45) switches.
• Also in the equipments 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 equipments, 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 authorised 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 equipments to parallel have the system.
See Fig. 6 to 14 for COM
port physical layout.
Fig. 37. 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 equipments.
Although the order of the connections of communication BUS
among equipments 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 equipments in order simplify the connection.
• The connection limit of the installation, will be determined by
the quantity of available equipments 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 equipments,
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 equipments 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. 37 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» equipments 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
equipments, it is essential. Switches of the panel board
have to allow isolating a UPS from the system against any
wrong operating and feeding the loads with the rest ones,
either during the preventive maintenance period or the
reparation of itself.
Therefore it has been considered appropriate and naturally,
to contemplate in the instructions of the equipment, the
operating of a system with «n» equipments 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 easier the preventive maintenance tasks or
intervention over the complete system, supplying the voltage
to the loads directly from mains, on the «bypass» mode
operating, 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 manoeuvring
of their switches.
Fig.38. 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 equipments, 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»
equipments 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

• 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 equipments, the «Paral. Slv. By» will not exist.
The UPS heriarchy relating to the rest of equipments of the system is
a dynamic depending on the status of the rest of the equipments:
–– «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 equipments only). It will become as «Reserved bypass
Slave», when it works as «Bypass Master». In those systems with
more than three equipments in parallel, the heriarchy 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 equipments 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
equipments in parallel, the heriarchy 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.
• Make sure that the inverter LED (c) is turned on (green), and bypass
LED (b) is turned off in all UPSs (see Fig. 34). If the led status is not
the correct one, contact with the S.T.S. (Service and Technical
Support).

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

˙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 equipments.
■ Equipments 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 equipments.
■ Equipments 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 OF THE 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. Through the keypad of the control panel ((3)
from Fig. 39), go down to «CNTL» submenu (screen 1.0), and
select «OFF». You will get to screen 1.2, asking you to shutdown
the unit by pressing (ENT), see Fig 38
.
˙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 electrolitic capacitors have
been discharged.
˙The equipment is completely shutdown.
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.

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 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 keypad of the control panel ((3)
from Fig. 39), go down to «CNTL» submenu (screen 1.0), and
select «OFF». You will get to screen 1.2, asking you to shutdown
the unit by pressing (ENT), see Fig 38.
˙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 shutdown 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 keypad of the control panel ((3) from Fig. 39). Select «CNTL»
and Press(ENT) into control submenu (screen 1.0), and then select
«ON» and Press(ENT) once. You will get to screen 1.1, asking you
to start the unit up yes or not, you can select Yes and pressing
(ENT). See screen diagram (Fig. 39).
The UPS supplies output voltage entirely protected against voltage
variations, electric noise, etc.
˙Wait for alarm message to appear:
˙Battery fuse holder switch or switch from UPS (Q3) can only be
turned «On» when the previous alarm message has been cancelled.
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.
˙The UPS supplies output voltage entirely protected against cuts,
micro cuts, voltage variations, electric noise, etc.

by default).
˙Alarm 8: When the inverter or PFC temperature sensors measure
temperatures over the programmed values (70ºC by default).
˙Alarm 9: This message appears when the battery switch is OFF
and the DC bus is charged to the battery voltage level, to inform
the user to switch ON the battery switch.
˙Alarm 10: This Alarm indicates that the bypass input voltage or the
bypass input frequency are out of margins. These margins are
programmable but by default the bypass voltage range is +12%/–
17% and the bypass frequency range is ± 0.5Hz.
˙Alarm 11: The UPS is on bypass for any reason. It must be

a whole, therefore this alarm is activated.
˙Alarm 73: In a system with parallel configuration, this alarm is
displayed in one of the equipments (or some) that detect(s)
communication errors, due to several reasons (parallel
communication cables are disconnected, or wrong connected, or in
bad status; wrong configuration of any of the equipments; etc.).
Therefore, one the equipments is set as a fix Master of the system,
and the rest of the equipments can only be slaves permanently (or
till the equipments are shutdown and they will be started up again
to test it).
˙Alarm 74: In a parallel system, with N+M configuration,
where:
N: nr equipments to size the system according to the maximum
permissible load.

the alarm 74 Lost of Redundancy, there will also be, as
minimum, (among others), the alarm 2 of Inverter overload
in all the equipments of the system.
˙Alarm 75: This alarm can be displayed for two reasons:
Input contactor from the equipment faults (it doesn’t close properly).
It is shown when the DC bus voltage, it is not kept at certain level
when closing such input contactor. The system can retry the
contactor test several times (see description of the Alarm 47 too).
˙Alarm 76: After the first error in the parallel system communication,
when one of the equipments has already been chosen as a Fix
Master in the system, a second error or break in the
communications has been detected by the Slaves equipments,
which will be blocked permanently (Rectifier and Inverter are
shutdown, output voltage is not supplied to the output of the
system), by displaying this alarm.
˙Alarm 77: Error in configuration memory

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
c
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
d
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
se
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 authorised 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 authorised technical staff.
8.2. WARRANT Y CONDITIONS.

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.
