3.3. Operating principle

Protect 2.33 2.0 is a double conversion system AC/DC, DC/AC with a sine wave output that gives safe protection in extreme conditions of power supply (variations in voltage, frequency, electrical noises, blackout and other power disturbances, etc…). Whatever the kind of load that has to be protected, these devices are prepared to assure quality and continuity in the electrical supply.

The operation is basically as follows:

•Rectifier, an IGBT three phase rectifier, converts the AC voltage into DC by absorbing a pure sine wave current (THD < 2,5 %*), and charging batteries at constant current / voltage.

•The batteries supply the power needed by the inverter in the event of mains failure.

•The inverter deals with transforming the voltage of the DC bus into AC by providing a sine wave, alternating output stabilized in voltage and frequency suitable for supplying the loads connected on the output.

*from 50 % load

16

•The basic double conversion structure is complemented by two new functional blocks, the static bypass commuter switch and the manual bypass commuter switch.

•The static bypass commuter switch connects the output load directly to the bypass network in special circumstances such as overloading or overheating and reconnects it to the inverter when normal conditions are restored.

•The manual bypass commuter switch isolates the UPS from the mains and from the loads connected on the output, so that maintenance operations may be performed in the UPS without any need to interrupt the supply to the loads.

3.3.1.Normal operation

With the mains present, the rectifier transforms the AC input voltage into DC, raising the DC voltage to a suitable level for supplying the inverter and to charge the batteries.

The inverter deals with transforming the voltage of the DC bus into AC, providing a sine wave alternating output, stabilized in voltage and frequency to supply the loads connected to the output (Fig.12).

3.3.2. Operation with mains failure

In the event of mains failure or power disturbance occur, the group of batteries supplies the power needed to supply the inverter.

The inverter continues working normally, independent of the lack of mains, and the back-up time of the device depends only on the capacity of the group of batteries (Fig.12).

When the battery voltage reaches the end of back-up time, the control blocks the output as protection against a deep battery discharge.

When the mains returns and following the first seconds of analysis, the UPS operates once more as in section “Normal operation”.

3.3.3. Operation with inverter not active

The inverter is inactive due to the existence of alarm conditions such as overloads, overheating, end of back-up time, etc. In this case the rectifier continues charging the batteries to maintain their optimal charge state.

The inverter is also inactive if the unit has not been started up with the keyboard. In this case, the rectifier will be inactive.

17

In all these cases the output voltage of the UPS is supplied by the emergency bypass line through the static bypass commuter switch (Fig. 12), provided that the EPO is inactive.

3.3.4. Operation in manual bypass

When we wish to perform some maintenance check on the device, it may be disconnected from the mains without any need to cut the power supply to the system and affect the critical load. The UPS may be altered, only by technical or maintenance personnel. For maintenance bypass follow the special instructions for that purpose (refer chapter 5.4).

3.4. Parallel operation

Fig.13:  Single line diagram for UPS parallel system

2 UPS’s can be paralleled to one UPS system for redundancy purposes or to double the maximal load level. Only identical UPS with the same ratings can be paralleled. Fig.13 shows the single line diagram of a parallel system of Protect 2.33 2.0 showing the power connections and the control bus cables. Two UPS running in parallel always do load-sharing. Parallel operation offers several advantages like higher availability or “modular” adaption of the UPS system to cover increasing power demands.

The parallel system management is based on a dynamic MASTER-SLAVE principle, where the first UPS in normal operating mode will become MASTER. It has the control of the second UPS (SLAVE).

18

There are two operation modes possible:

•Redundant system: As long as both UPS do not exceed the level of 50 % load one UPS is able to take over the full load if one of the UPS in the system fails. After the failed UPS was repaired it can be restarted and will recover the redundancy condition. In case of more than 50 % load per UPS the system will generate an alarm. In case one UPS fails at more than 50 % load per UPS the second UPS will take over and will run into overload. It will supply the load according to the UPS overload capability. After that condition both UPS will switch to bypass.

•Parallel system for power enhancement: Paralleling two UPS will double the maximum power. There will be no alarm “Redundancy lost”.

19

4.Installation

•Refer to the safety instructions.

•Ensure that the data on the rating plate of the UPS match those required for installation.

•Any incorrect connection or handling may cause damage to the UPS and/or the loads connected to it. Read these instructions carefully and follow the steps indicated in the correct order.

•This UPS must be installed by qualified staff and is usable by personal with no specific training. All staff using this equipment should become familiar with the contents of this of this “Manual”.

•Should a power increase be required in the future through parallel switching, consider that larger cable diameters may be required. Likewise, the additional installation of an external manual bypass switch for each device is recommended.

4.1. Important safety instructions

As this is a device with class I protection against electric shocks, it is essential to install a protective earth conductor (connect earth (()). Connect the conductor to the terminal (X5), before connecting the power supply to the UPS input.

All connections in the device, including those for control (interface, remote control, ...), will be performed with the switches at rest and without any mains feed present (UPS power line cut off “Off”).

It must never be forgotten that the UPS is a generator of electrical power, users must take all necessary precautions against direct or indirect contact.

Warning labels should be placed on all primary power switches installed in places away from the device to alert the electrical maintenance personnel of the presence of a UPS in the circuit. The label should contain the following or an equivalent text:

Before working on this circuit:

•Isolate Uninterruptible Power System (UPS).

•Then check for hazardous voltage between all terminals including the protective earth.

Risk of voltage feedback

20

Once the power supply is connected to the input of the UPS (with static bypass included or with an independent static bypass line), although the inverter is “Off” (shut-down), it does not mean that no output voltage is available at the output terminals.

To do this, it is required to switch (Q1a), (Q4) and (Q2) to position “Off”. It is possible that the UPS might be supplying output voltage from the manual bypass, so this must be considered for the purpose of safety. If the output power supply of the UPS has to be interrupted in this situation, deactivate the switch (Q5).

In devices with battery terminals, precautions must be taken as they are not electrically insulated from the alternating input line, and there might be dangerous voltage between the battery terminals and the ground.

4.1.1. Battery safety instructions

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

For units requested without batteries, the acquisition, installation and connection of the batteries will always be done by the customer and it is under his responsibility. The relevant information on the batteries (number, capacity and voltage) are indicated in the battery label pasted beside the nameplate of the equipment. Strictly respect this data, the battery polarity connection and the circuit diagram provided with this documentation.

The battery supply can involve the risk of electric shock and can produce high short circuit current. Observe the following preventive measures before manipulating any terminal block identified in the labeling as “Battery”:

•Disconnect the corresponding protection elements.

•When connecting a battery cabinet to the equipment, respect the cable’s polarity and color (red-positive; black-negative) indicated in the manual and in the corresponding labeling.

•Wear rubber gloves and shoes.

•Use tools with insulated handles.

•Removes watches, rings or other metal objects.

•Do not place metal tools or objects on the batteries.

•Never manipulate directly with your hands or through conducting objects, do not short the battery terminal block or the battery enclosure.

•Never short the battery terminals as it involves a high risk. It may result in damage to the equipment and batteries.

21

•Avoid mechanical exertions and any impacts.

•Do not open or damage the battery. Released electrolyte can be harmful to the skin and eyes.

•Do not dispose of batteries in a fire. The batteries may explode.

•In case of contact with the battery acid, wash immediately with plenty water and immediately call the nearest medical facility.

•Batteries involve a serious risk for health and for the environment.

•Their disposal should be carried out according to any existing laws.

4.1.2.Cabinet access

All the UPS units and battery packs have terminals as power connection parts and a DB9 connector for the communication channel located in the inside of the equipment. Follow the steps described next to gain access to them:

•Unlock the lock (CL) with the special supplied key.

•Rotate it 45º clockwise and open the front door (PF) completely.

DB9 connectors from communication ports and terminals for remote EPO button will be revealed.

•Remove the screws (t1), which fix the terminal cover (TB) inside of the cabinet and remove it; the power terminals will be revealed.

•The connecting cables can be connected to the terminals located below the clamps and can be fixed to the aluminum rail.

•Once the connection of the UPS is complete, replace the cover (TB) and close the door (PF) with the lock (CL).

The cable cross section of the bypass, input and output lines shall be determined from the maximum currents for the two first and from nominal ones for the output, by respecting the local and/or country low voltage electro-technical standards.

To calculate the cross cable sections, take the Figures of the current as stated in table 1 depending on the model and nominal voltage value of the UPS. In the nameplate of the equipment are printed the nominal currents as stated in the safety standard EN-IEC 62040-1.

Safety characteristics:

•For the input power failure circuit breaker Type B.

•For the output (supply loads) , circuit breaker with tripping characteristics C.

Minimum currents are stated in table 1 depending on the model and nominal voltage value of the UPS.

22

The cross sections of all of the connecting cables must in each case be sized according the fuse selected.

In cases were added input, output or bypass peripherals to the UPS (e.g. transformers or autotransformers) currents are stated in the nameplates of the peripherals and must to be taken into account in order to use suitable cross sections. Always respect the local and/or national low voltage electro-technical regulations.

Table 1:  Input, output and bypass currents for standard single phase Protect 2.33   standard systems

If isolation transformers are present in the installation at the input and/or output of the UPS, they have to be fitted in with protection against indirect contacts (earth leakage breaker) at the output of each transformer. Electrically insulated of the transformer will impede the tripping of protection installed at the primary winding of the transformer in cases were an short circuit in the secondary winding (output of isolation transformer) may occur.

Note that all neutral terminals for input, output and battery are connected inside the UPS.

The cable routing or housing passages supplied fitted to the metal structure are those recommended to correctly fix the input, output and bypass wires with the sections determined by the national low voltage electro-technical regulations in accordance with the currents of the device.

23

If these sections should have to be changed for any reason, this should be implemented with a separate distribution box and the sections indicated should be maintained from the device to the distribution box.

In standard equipment up to 40 kVA, batteries are supplied inside the UPS enclosure and for higher power rates they are supplied in a separate cabinet. By default, the UPS has a battery fuse-holder switch (Q3) with 3 fuses for models up to 40 kVA or battery switch (Q3) for models with higher power rate.

From 60 kVA upwards, no UPS internal batteries are installed, instead you will find a circuit breaker (Q8) in the battery cabinet. Fuses are includes in the delivery of the UPS. Open the fuse box (Q3) and (Q8) and install the three fuses. Connect the battery with the UPS and then follow the startup procedure prompted via the UPS display.

IMPORTANT FOR YOUR SAFETY: Do not turn the battery fuse holder switch or switch (Q3) located in the equipment or its equivalent (Q8) in the battery cabinet to “On” (Close) until the equipment is switched on completely, because it can cause irreversible damage to the equipment or accidents.

4.2. Set up and installation

4.2.1. Unpacking and content checking

On receiving the device, make sure that it has not suffered any damage during transport. Make all damage claims to your supplier or to our company. Check the data in the nameplate, which is fixed inside the front door (PF) and that it corresponds to that specified in the purchase order. To check this, it will be necessary to unpack the UPS. If this is not possible, any non-conformity must be sent at the earliest possible date, quoting the device manufacturing number and any references on the delivery remittance.

When the device has been accepted, it is best to pack the UPS away once more until it is to be commissioned in order to protect it from any possible mechanical knocks, dust, dirt, etc.

The packaging of the device consists of a wooden pallet, a cardboard or wooden surround (depending on the case), expanded polystyrene corner pieces, polyethylene sleeve and band. All are recyclable materials and should therefore be disposed of according to current regulations. However, we recommend that the packaging should be kept in case its use is necessary in the future.

To unpack, cut the bands on the cardboard surround and remove it from above.

24

If the surround is made of wood; remove the corner pieces and the plastic sleeve first. The UPS will be unpacked on the pallet, to lower it, suitable means (fork truck, crane, hoist) must be used that can operate within the safety tolerance limits for the approximate weights displayed in tables 5 and 6 (Page 73 – 75).

4.2.2. Storage

Equipment should be stored in a dry, ventilated place protected from rain, splashing water and chemicals. It is recommended to store the UPS and batteries in their original packing. This offers the best protection during transport and storage.

If ordered with the UPS, closed lead accumulators are built into the UPS or the battery cabinet. To ensure problem free operation of the 10 – 20 kVA equipment you should not store for longer than 3 months and absolutely no longer than 6 months.

If longer storage is required, the batteries must be recharged after the aforementioned periods

Store batteries or equipment with built-in batteries at 20 – 25 °C.

Deviation from this may result in a reduction of maximum storage availability.

4.2.3. Transportation to site

All UPSs are fitted with rollers to facilitate transport to site. Be sure to observe tables 5 and 6 (page 73 – 75) for indicated weights in the selection of an appropriate site and the selection of transport route (floor, elevators, stairs etc.)
