1.- GENERAL INFORMATION.

1.1.- General description of the UPS.

This UPS is built in a metallic structure, where the electronic power is located in and we have access to it through the frontal door.The external covers of the equipment can be removed completely in order to guarantee an easy start up from any point in front ofany event.In the right frontal door, it is located the user interface panel, for controlling and managing the UPS.Due to the high power rate of the UPS, it doesn’t have any battery string inside; they are located in one or several cabinets.The cooling system of the equipment is based on a hydraulic system (made of water and glycol) and forced cooling, the air is takenfrom the baseboard of the UPS and exhausted through the frontal cooling grids placed in the exchanger stage, and located on thefrontal left side of the equipment.

1.1.1.- UPS applications.

This new UPS has been designed to supply stabilized and filtered voltage to sophisticated electronic devices (particularly to datacentres), which must have a power supply free of voltage and frequency fluctuations. Among them there are: hospitals, policestations, highway tunnels, broadcasting stations, banks, technical offices, etc.

1.1.2.- Power and back up time.

Thanks to its modular configuration, the power rates of this series are between 160 KVA and 300 KVA.It is not foreseen any internal battery string, so to achieve the wanted back up time is needed the use of additional cabinets them.

1.1.3.- Safety and easy use.

All the controls are properly insulated and disconnected from hazardous voltages.The control for overloads and overtemperatures guarantee an immediate intervention, in case one of them occurs during itsoperation.Through the frontal panel, the end-user can visualize the status of the UPS and make transference and shutdowns manoeuvres inan easy way . See chapter 3.There is the possibility to connect one or more external E.P.O. buttons (not supplied). Thanks to them, in case of fire, it is possibleto control the complete UPS shutdown. See chapter 2.7.4.The UPS monitoring can be remotely managed in an easy way either through a personal computer with a specific communicationsoftware(optional), or through a remote panel, optional too, they are essential in case of unattended places. See chapters1.2.5–1.2.6.

1.2.- Configuration and optional devices.

1.2.1.- Standard configuration.

The standard configuration is to assemble the UPS in only one cabinet, which will have the same dimensions in all the possibleconfigurations and sizes:

- Six pulses: 160 – 300 kVA- Twelve pulses: 160 – 300 KVA- Twelve pulses + THD filter: 160 – 300 KVA

- 8 -

1.2.2.- Battery cabinet.

Under request, the UPS can be supplied with the suitable batteries to have the wanted back up time.The batteries are built in a separate cabinet and they have their own protection and breaking devices.Due to their external location, it is a must to foresee their protection.

1.2.3.- Transformer cabinet.

The galvanic isolation transformer is built in a separate cabinet (output -rectifier mains -bypass mains) for specific uses.The standard transformer is three phase/three phase with ratio 1:1, but it can be supplied with different ratio, depending on thecustomer needs.

1.2.4.- Remote communication card.

The UPS can be monitored through theremote communication card (CS0098).This monitoring can be done either througha PC with a specific software connectedto CN3, or through the dry contactslocated in the terminal strip M1. Thesystem already has a remotecommunication card and a slot to placean optional one, if it is requested (formore information, see chapter 2.7.-Auxiliary connections of the UPS).

1.2.5.- UPS management software.

The monitoring software Generex “UPS MANAGEMENT” allows tocommunicate the UPS with a PC or with an IT network, which runsunder Windows, Win-NT, Novell, OS2, Dec or Lynux platforms.This software allows the control of one or several UPS used in thesame IT network (LAN) of personal computers (For more information,see chapter 2.7.- Auxiliary connections of the UPS).

1.2.6.- Remote panel.

The remote panel allows displaying the operation of the UPS remotely,by repeating the status of the main stages with LED indicators andan acoustic alarm. (For more information, see chapter 2.7.- Auxiliaryconnections of the UPS).

1.2.7.- Remote E.P.O. button.

The remote E.P.O. button is a safety system that allows shuttingdown the UPS completely in case of an emergency. (For moreinformation , see chapter 2.7.- Auxiliary connections of the UPS).

- 9 -

1.3.- Operating principle.

The described UPS is an On-line double conversion equipment with automatic bypass according with the European standardEN62040-3. This kind of UPS makes a double conversion of the input voltage in a continuous way and without any interruption.

As the loads are not connected directly to the mains there are not interferences transfer to them; also, the double conversionguarantees a stabilized energy, both voltage and frequency, which is the ideal for the correct operation of the critical loads.

When the input voltage is out of the permissible range of the equipment or there is a black out, the load is fed from the energy storedin the batteries.The system is provided with an automatic bypass; in case of UPS fault or overload, the bypass connects the critical loads to thebypass mains directly, which allows to restore the normal operating conditions of power supply without any interruption. See figure1.3.1.

1.3.2.- Input, power module and output.

From the input terminals, the mains is connected through the MAINS INPUT I1 switch to the power module.During a mains failure or it is out of the permissible UPS range, the step-up rectifier module, makes the DC/DC conversion from thebattery and in case of restoring it makes the AC/DC conversion from the mains (normal operation).

After, the direct current supplies the inverter module, which is in charge of inverting the DC to alternating current making it suitablefor the load requirements.The last module is the automatic bypass; it connects, in normal operation, the filtered and regenerated energy from the invertermodule to the loads. In case of UPS fault or overload, the UPS output will transfer to the bypass line; in this situation, the mainsis in charge of feeding the loads. Once the fault, which has provoked the transference to bypass, is solved, the static switchtransfers back the load to the inverter automatically.Through the UPS OUTPUT SWITCH I4, the loads are supplied in a filtered, regenerated and stabilized way. See diagram 1.3.1.

- 10 -

1.3.3.- Control and auxiliary circuits.

The control logic is in a specific card (CS0090) and it is equal to “the intelligence” of the UPS. It is in charge of managing theoperation of the rectifier step-up, inverter and bypass from the comparison, in phase, of the signs detected by the power module.Also the control logic manages three additional cards: the battery charger, the auxiliary power supply and the communicationinterface.

The battery charger guarantees the perfect recharging of those external battery strings that are connected to the UPS. Thecommunication interface takes the signals from the control logic and they are converted to the foreseen protocol for the UPS frontalpanel and relay card. Contrary to it, the communication interface sends the criteria coming from the frontal panel (forced transferto bypass) and/or from the relay card (E.P.O.) to the control logic, doing at the same time, the transference of the UPS to the bypassline and/or shutting down the UPS immediately, respectively.

The communication interface can control a part from the standard relay card an additional one, which is optional.The auxiliary power supply feds all the PCB’s and electronic parts of the UPS.

1.3.4.- Batteries.

The battery supplies energy to the system when the mains is out of range or there is a black out. In the rest of cases, the batterycharger module recharges that battery in a constant way to leave it ready again.

1.3.5.- Manual bypass.

The use of the manual bypass is foreseen for those cases that the UPS must be excluded from the loads and they must still besupplied from the mains(example: UPS shutdown, fault,...). It is a circuit, which is turned on/off through the MANUAL BYPASSSWITCH I4 and it is located in the frontal part of the UPS. For more information, see chapter 4. In normal running, this switch isin off position with a safety mechanical lock (it is padlocked).

1.3.6.- Frontal panel.

The UPS is controlled through the frontal panel, and it is possible to manage the controls, visualize and reboot the alarm circuits.The panel has an LCD that allows displaying the UPS operating, the load status and any measurement (see chapter 3).

2.2.- Reception and identification.

After removing the packing, inspect the UPS and battery cabinet visually (inside and outside) to detect possible damages inthe unit due to the transport. If there is any damage in the structure, it is convenient to claim to the transport agency or dealerimmediately. Also, it is convenient to compare the supplied good with the delivery invoice.In the door of the equipment there is the adhesive tag label with the type, power and serial number of the equipment.

2.3.- Storing.

If the equipment is not installed immediately, it must be stored in a environment protected from high humidity and heat sources(from +5 to +40 °C, non-condensing humidity lower than 95%).

When the battery cabinet is also supplied, it is a must to assure that the period time between the last recharge of the batteries andthe next one will not be higher than 6 months. Once this period is overcame, the UPS will be connected to the mains and startedup provisionally, during the needed time in order to recharge the batteries .

2.4.- UPS location.

All the sizes and configurations of this series have been designed with the same structure. Their mechanical features are describedin the tables 2.4 a-b-c.

The dimensions and weight are different due to the liquid-air exchanger of the equipment.

For its handling, remind you that the equipment, less in those particular agreements, it is sent and joined with the exchanger,therefore it is necessary to take note of the dimensions and weight of the used version.

The cabinet, without the packing, can be transported with the help of a forklift, either from the front or from the side, and movedtill the installation location.Remind you, that the UPS has bottom entry cable (on the right and under the baseboard support ) (fig. 2.4).

4.1.- Introduction.

This chapter describes all the control devices of the UPS at the user disposal to use the system properly. The UPS can be runningunder one of the following operating modes:

• Normal mode. The UPS feeds the load. The UPS is running normally and uses the input mains to fed the loads and torecharge the batteries. This operating mode guarantees the non-interrupted power supply to the loads.

• Internal automatic bypass mode. The load is fed by the mains. In case of failure and/or inverter overload, the powersupply of the loads is guaranteed thanks to the bypass line (reserve). This operating mode doesn’t guarantee the non-interrupted power supply to the loads.

• Maintenance bypass mode. The UPS is shutdown. The load is connected directly to the mains through the maintenanceor emergency bypass line. This operating mode doesn’t guarantee the non-interrupted power supply to the loads.

• Battery mode. The UPS feds the load. The UPS is running and uses the batteries to fed the loads because there is a mainsfailure. This operating mode guarantees the non-interrupted power supply of the loads till the end of autonomy.

4.2.- Power switches.

The power switches of the UPS are located behind the right front door and they have been installed vertically in the followingorder (see fig. 4.3):

• Input mains switch (I1): It connects the UPS with the input mains.

• Output switch (I4): It connects the UPS with the critical loads.

• Input bypass switch (reserve) (I2): It connects the UPS with the bypass mains (reserve).

• Manual bypass switch (I3): It allows excluding the UPS by keeping the LOADS fed the mains. It is protected by amechanical lock (padlock) to avoid accidental manoeuvers.

All the power switches of the UPS have been described less the battery one, which is located in the battery cabinet, outfrom the UPS cabinet.To isolate the equipment completely from hazardous voltages, the battery SWITCH must be turned OFF, althoughit is not located in the cabinet.Likewise, remind you that there are charged capacitors inside the converters stages, therefore you must wait

5.- UPS IN PARALLEL.

5.1.- Predisposition of the system.

The installation of more than one UPS in parallel needs one or more than one distribution boards. The board type guaranteesdifferent operating levels depending on the complexity of the adopted solution. Next, it is described the standard solution,usually suggested, that guarantees the operability of the total system (fig.5.1).

It has been foreseen the cross section of all power supply cables of each equipment, the feedback cross section cable andthe battery protection.

Likewise, it is advisable to install a general bypass in the system, with a functional blocking. This blocking is needed to avoidpossible damages to the system.

The stated solution allows checking all the operations during the installation and maintenance periods of each equipment.

The general manual bypass allows isolating the complete system with no-interruption in the feeding of the loads.The complexity of the system makes that the status of each UPS must be supervised through a remote panel or SNMP. See chapter1.2.4.

6.- EQUIPMENT WITH FAILURES.

6.1.- Generic alarms.

In case of faults in the UPS, the screen, by default, will be replaced by one alarm message, which can be one of the following:

When the UPS has failures that can’t be solved, it is not able to guarantee the non-interrupted power supply to the loads. Therefore, it isbetter to make the EMERGENCY BYPASS manoeuvre and leave the equipment isolated and shutdown, before calling the Service andTechnical Support.

In case of parallel equipments, the UPS with faults is excluded from the parallel operation, however it must be isolated byturning off the OUTPUT SWITCH and shutting down the equipment. Next call to the Service and Technical Support.In case of temperature alarms, be sure that there is not any cooling liquid leakage (liquid level alarm in the LCD panel). In caseof liquid leakage, the equipment must be shutdown and isolated, and transferring it to maintenance bypass. Call to theService and Technical Support.

6.2.- Fire principle.

In case of fire, remind you that CO2 or dust extinguisher must be used only. The equipment must be shutdown completelyand transferred to maintenance Bypass, and the battery switch must be turned off.

In case of parallel equipments, the OUTPUT SWITCH of that UPS must be turned off immedately and the rest of the switchestoo, including the battery one.

ALARM MESSAGE CAUSE ACTION

6.3.- Failures depending on the load type.

Frequently some wrong operations are attributed to the UPS, meanwhile, in fact, they are normal reaction in front of faultyloads or installations.Next, it is described the most common situations:

• The load of the UPS is still receiving power supply from the bypass mains although the inverter is running properly: Itdepends on a high inrush current, which makes a high dropping voltage, and if it is reiterated, provokes the transfer of theload to bypass.The system, after three consecutive attempts to transfer back to inverter, the static switch is blocked into the bypass linein order to protect the inverter. Therefore, the load current must be checked, and eliminate that load which makes thoseovercurrents.The reiterated inrush current can’t be higher than 2,5 times of the root mean square value.

• The OUTPUT voltage accuracy of the UPS is bad: It can be due to unbalanced loads or those loads that provokes distortion.

7.- SCHEDULED MAINTENANCE.

The UPS needs, along of its useful life, some scheduled maintenance cycles in order to maintain the reliablity of operatingand efficiency.The scheduled maintenance must be done by the UPS dealer company or by a specialised company, recommended by thedealer company.

7.1.- Yearly maintenance (or half-yearly in some critical cases).

The yearly maintenance has the following actions and checking:

• Equipment cleaning.• Interface and control PCBs cleaning.• Checking the bolt torque and the electrical connections (UPS and battery).• Checking the cooling efficiency.• Cleaning and checking the efficiency of the liquid-air exchanger.• Checking the no leakage of cooling liquid.• Checking the inverter output wave.• Checking the output voltage/frequency.• Synchronisation checking.• Signalling, alarms and E.P.O. operation checking.• LCD panel calibration with a calibrated instrument.• Checking the operating of the manual and automatic controls.• Checking the operating of the transfer circuits.• Mains failure test in the UPS to check the battery efficiency and the correct operation of the battery charger.

7.2.- Scheduled part replacement.

• In a triennial period the axial 120x12 mm and centrifugal fans must be replaced.• In a biennial period the cooling liquid must be replaced.• In four years period the power electrolytic capacitors and cooling pump must be replaced.• Every six years the power AC capacitors must be replaced .

Important: The battery replacement, will depend on the type used, therefore it will depend on the batterymanufacturer instructions.
