3、rmation concerning the installation and operation of Liebert ITA 16kVA and 20kVA UPS (hereinafter referred to as UPS).Please carefully read this manual prior to installation.The UPS must be installed, commissioned and serviced by engineers designated by the manufacturer or its agent. Failure to obse

4、rve this could result in personnel safety risk, UPS malfunction and invalidation of warranty.The UPS has been designed for commercial and industrial use only, and is not recommended for use in life support applications.This is a Class A UPS product. In a residential environment, this product may nev

5、ertheless cause radio interference, in which case, the user is required to take additional measures to reduce the interference.Warning1. Before moving or re-wiring the UPS, disconnect all the inputs and make sure that the UPS is completely shutdown. Or else, the output end may carry live voltage.2.

6、Liquid or other irrelevant external objects are prohibited inside the UPS.3. In case of a fire, a dry chemical fire extinguisher is essential. Using a foam fire extinguisher will cause electric shock.4. The output neutral line of the UPS is from the input, after the neutral line is suspended by the

7、upstream protection devices, the output neutral line will be unconnected.Conformity and standardsThe UPS complies with 2006/95/EC (LV Safety) and 2004/108/EC (EMC), with Australia and New Zealand EMC Framework (C-Tick) and with the following product standards for UPS:IEC 62040: 2008 General and safe

8、ty requirementsIEC62040-2: EMC requirements, Class C2 compliantIEC62040-3: Performance requirements and test methodsThe UPS installation should follow the above instructions and use the accessories specified by manufacturer.Warning: high leakage current1. Earth connection is essential before connect

9、ing the input power (AC mains and battery included). 2. Earth leakage current ranges from 3.5mA to 1000mA.3. Transient and steady-state earth leakage currents, which may occur when starting the equipment, should be taken into account when selecting instantaneous residual current circuit breaker (RCC

10、B) or residual current detector (RCD). 4. Note that the earth leakage current of the load will be carried by RCCB or RCD.5. This equipment must be earthed in accordance with the local electrical codes.Warning: backfeed protectionThe UPS has a zero-voltage contact closure signal available for use wit

11、h an external automatic circuit breaker (single power), to protect against backfeeding voltage to input terminal through the static bypass circuit. Namely, before operating the circuit, isolate the UPS firstly, and then check the dangerous voltage between the ports, and that between the ports and ea

12、rth.Maintainable components1. All internal maintenance and servicing procedures of the equipment should be carried out only by trained personnel. Components behind the protective cover which can only be removed by using a tool are restricted to service personnel. 2. The UPS meets the safety requirem

13、ents completely in operator access area. Only service personnel can contact with the hazardous voltage inside the UPS. However, the risk of contacting these voltages is minimized because the components with hazardous voltage may be contacted only by using a tool to remove the protective cover. No ri

14、sk will exist if you follow the general norms and in accordance with the procedures recommended in this manual on equipment operation.Warning: battery high voltage1. All the physical service and maintenance of the battery are performed by the trained technicians.2. Operation on the battery will resu

15、lt in electric shock and high short-circuit current, therefore, before operating the battery, the following should be observed:Remove the watches, rings and other metal objects.Use the tools with insulation handle.Weare rubber glove and shoes.Avoid to place the tools and metal objects on the battery

16、 surface.Cut off the charge power supply before connecting or disconnecting the battery terminals.Check whether the battery is earthed accidently, if yes, please disconnect the earthing. Contacting any earth battery parts will result in electric shock. Therefore, make sure that the battery is not ea

17、rthed during installation and maintenance.3. Battery manufacturers provide the details of the precautions to be observed when working on, or in the vicinity of the batterys. These precautions should be followed implicitly at all times. Attention should be paid to the recommendations concerning local

18、 environmental conditions and the provision of protective clothing, first aid and fire-fighting facilities.ContentsChapter 1 Product IntroductionLiebert ITA 16kVA and 20kVA UPS (UPS for short) is an intelligent online UPS system with sine wave output developed by Emerson Network Power Co., Ltd.

29、ing principle of the UPS is shown in Figure 1-4.Figure 1-1 UPS operating principle1. The UPS is composed of mains input (main and bypass), I/O filter, rectifier/PFC, charger, inverter, bypass, battery, DSP controller, auxiliary power and UPS output.2. When the mains is normal, the rectifier will sta

30、rt, and the charger will charge the battery string. Before turning on the UPS, the output voltage is the bypass voltage, and the mains supplies power to the load through the bypass. After turning on the UPS, the electronic transfer switch connects the inverter output to the load, and the mains suppl

31、ies DC power to the inverter through the rectifier/PFC circuit. The inverter then converts DC power into pure sine wave AC power, and supplies the AC power to the load through the electronic transfer switch.3. When the mains is abnormal, the rectifier/PFC circuit boosts the battery voltage and suppl

32、ies it to the inverter. The inverter then converts it into pure sine wave AC power, and supplies the AC power to the load through the electronic transfer switch. 4. After the mains returns to normal state, the UPS will automatically transfer from Battery mode to Normal mode, the mains supplies DC power to the inverter through the rectifier/PF
