4. PRESENTATION.4.3.1. Normal Mode4.1. SYSTEM CONFIGURATIONThe Modular UPS is configured by the following part: Powermodules, Bypass & Monitoring module, and cabinet with manual Bypass switch. One or several battery strings should beinstalled to provide backup energy once the utility fails. TheUPS structure is shown in Fig. 1.The inverter of power modules continuously supply the criticalAC load. The rectifier/charger derives power from the AC mainsinput source and supplies DC power to the inverter while simultaneously FLOAT or BOOST charging its associated backupbattery.Manual BypassStatic BypassManual BypassBypassStatic rgerDC/DCCharge/Discharge.4.3.2. Battery ModeFig. 1. UPS Configuration4.2. POWER MODULEThe power module structure is shown as Fig. 2. The power module contains a rectifier, an inverter, and a DC/DC converter forcharge and discharge of the external batteries.BatteryBatteryOutputFig. 3. Normal mode operation ssUpon failure of the AC mains input power, the inverter ofpower modules, which obtain power from the battery, supplythe critical AC load. There is no interruption in power to thecritical load upon failure. After restoration of the AC mainsinput power, the” Normal mode” operation will continueautomatically without the necessity of user intervention.Manual BypassRectifierAC/DCInverterDC/ACOutputDC/DCFig. 2.

4.3.3. Bypass ModeManual BypassIf the inverter overload capacity is exceeded under Normal mode,or if the inverter becomes unavailable for any reason, the statictransfer switch will perform a transfer of the load from the inverterto the bypass source, with no interruption in power to the criticalAC load. Should the inverter be asynchronous with the bypass, thestatic switch will perform a transfer of the load from the inverterto the bypass with power interruption to the load. This is to avoidlarge cross currents due to the paralleling of unsynchronized ACsources. This interruption is programmable but typically set to beless than 3/4 of an electrical cycle, e.g., less than 15ms (50Hz) orless than 12.5ms (60Hz). The action of transfer/re-transfer can alsobe done by the command through monitor.Manual ChargerDC/DCFig. 7. ECO Mode operation diagramNote:The battery may become exhausted following an extendedAC mains failure. The inverter shuts down when the batteryreaches the End of Discharge Voltage (EOD). The UPS maybe programmed to “System Auto Start Mode after EOD”. Thesystem starts after a delay time when the AC mains recovers.The mode and the delay time are programmed by the commissioning engineer.4.3.4. Maintenance Mode (Manual Bypass)A manual bypass switch is available to ensure continuity of supplyto the critical load when the UPS becomes unavailable e.g. duringa maintenance procedure. (See Fig. 6).Manual BypassStatic BypassRectifierAC/DCBatteryInverterDC/AC4.3.6. Auto-restart ModeFig. 5.

ECO ModeTo improve system efficiency, UPS rack system works in Bypassmode at normal time, and inverter is standby. When the utility fails, the UPS transfers to Battery Mode and the inverterpowers the loads.8SALICRU

5. INSTALLATION INSTRUCTIONIf external batteries are to be used, the battery circuit breakers(or fuses) must be mounted as close as possible to the batteries, and the connecting cables should be as short as possible.5.1. LOCATIONAs each site has its requirements, the installation instructionsin this section are to act as a guide for the general proceduresand practices that should be observed by the installing engineer.5.1.1. Installation EnvironmentThe UPS is intended for indoor installation and uses forcedconvection cooling by internal fans. Please make sure there isenough space for the UPS ventilation and cooling.Keep the UPS far away from water, heat and inflammable andexplosive, corrosive material. Avoid installing the UPS in theenvironment with direct sunlight, dust, volatile gases, corrosivematerial and high salinity.Avoid installing the UPS in the environment with conductivedirt.The operating environment temperature for battery is 20ºC25ºC. Operating above 25ºC will reduce the battery life, andoperation below 20ºC will reduce the battery capacity.5.1.2. Site SelectionEnsure the ground or installation platform can bear the weightof the UPS cabinet ,batteries and battery rack.No vibration and less than 5 degree inclination horizontally.The equipment should be stored in a room so as to protect itagainst excessive humidity and heat sources.The battery needs to be stored in dry and cool place with goodventilation. The most suitable storage temperature is 20 ºC to25ºC.5.1.3. Size and WeightThe size of three views for the UPS cabinet is shown in Fig. 11.Attention:Ensure there is at least 0.8m before the front of the cabinet soas to easily maintain the power module with the front door fullyopen and at least 0.5m behind for ventilation and cooling.The battery will generate a little amount of hydrogen andoxygen at the end of charging; ensure the fresh air volume ofthe battery installation environment must meet EN50272-2001requirements.ModuleUnitsDimensions WxDxHmmWeightKg101520590 x 440 x 1342122.522.5Table 2.

6. POSITIONING6.1. POSITIONING CABINETThe UPS cabinet has two way of supporting itself: One is to support itself temporarily by the four wheels at the bottom, makingit convenient to adjust the position of the cabinet; The other isby anchor bolts to support the cabinet permanently after adjusting the position of the cabinet. The supporting structure isshown in Fig. 20.6.2. INSTALLING POWER MODULEThe installation position of power module is shown in Fig. 21.Please install the power modules following the principle offrom bottom to top to prevent inclination of the cabinet due tohigh center of gravity. The steps of installing power module areas follows:1. Ensure the cabinet is fixed and no damage to the body andinserting port of the power module.2. Hold the handler and the body of the power module by twopersons at each side.3. Insert the module in the installation position, and push itinto the cabinet smoothly.4. Fix the module to the cabinet though the mounting holeson two sides of the front plate of the module (See Fig. 21right).5. Installing Power Module done.1- Anchor bolts2- WheelsFig. 20. Supporting structure (Bottom view).The steps to position the cabinet are as follows:1. Ensure the supporting structure is in good condition and themounting floor is smooth and strong.2. Retract the anchor bolts by turning them counterclockwiseusing wrench, the cabinet is then supported by the fourwheels.3. Adjust the cabinet to the right position by the supportingwheels.4. Put down the anchor bolts by turning them clockwise usingwrench, the cabinet is then supported by the four anchorbolts.5. Ensure the four anchor bolts are in the same height and thecabinet is fixed and immovable.6. Positioning done.Attention:Auxiliary equipment is needed when the mounting floor is notsolid enough to support the cabinet, which helps distribute theweight over a larger area. For instance, cover the floor with ironplate or increase the supporting area of the anchor bolts.161-Bypass module2- Power module3-10# Power module4- 2# Power module5- 1# Power module6- Mounting holesFig. 21.

Note:The installing method of bypass module is the same as thepower module.6.3. BATTERYThe battery set can be based between 36 and 44 blocks connected in serial, but it will always be an even number due tothe internal structure of the equipment, which needs a mid tapor central point (neutral) of them. At the same time, the back uptime together with the required power to feed the loads establishes the needed capacity of the battery in Ah.In Fig. 22, “N” means the total quantity of battery blocks connected in serial, being able to select it among the figures abovestated.Fig. 22. Battery string wiring diagram1- Signal Cables2- Power Cables3- Blanking plateFig. 23. Cable entryDanger:The battery terminal voltage is of more than 400Vdc, pleasefollow the safety instructions to avoid electric shock hazard.Ensure the positive, negative, neutral electrode is correctly connected from the battery unit terminals to the breaker and fromthe breaker to the UPS system.6.4. CABLE ENTRYCables can enter the UPS cabinet from the top. Cable entry ismade possible through a blanking plate fitted at the top of theequipment. The cable entry is shown in Fig.23.6.5. POWER CABLES6.5.1. SpecificationsThe «Recommended installation» information for each inputand output setting is available with the supplieddocumentation, manual and/or CD. In that information is shown thecircuit diagram, as well as the protection size and minimum crosssection of the wires that are connected to the equipment, taking intoaccount the nominal operating voltage. All figures are calculated fora maximum total cable length of 30 m between the distributionpanel board, equipment and loads.
