Note Confirm the right connection of hot line and neutral line and proper earthing. For hot standby UPS, the batteries of master UPS and slave UPS must be connected separately.
Chapter 3 Operation 3.1 Operating Mode 3.1.1 Normal Mode When the input Utility voltage and the load are within specifications, the load is supplied by inverter, which draws float-charges or equalize-charges the battery. When in Normal mode, the Utility indicator and inverter indicator on the LCD panel be green in colour ,as shown in Fig. 3-1.
Chapter 3 Operation Note Under this mode, if the bypass power fails or bypass voltage exceed the bypass voltage windows. , the UPS will not provide power to the load. 3.1.3 Battery Mode When the UPS is in Normal mode, in the event of Utility failure or Utility voltage outside tolerances, the rectifier and charger will turn off , the battery begins to discharge and supply the load through inverter.
Although the battery had been fully charged at factory before delivery, the transport and storage may result in loss of capacity , hence charging the battery for 8 hours is required before installing the UPS , so as to ensure adequate battery backup time. 3.1.4 ECO Mode ECO mode is the economic operation mode.
Chapter 3 Operation 3.2 Operation 3.2.1 Startup and Initialization After checking and making sure that the input and output cables are connected correctly, turn on the Utility switch and the bypass switch (for long backup time UPS, turn on the battery switch before closing the Utility switch). Then the system starts up, the internal fan begins to run, and the system begins to conduct self-test.
Page 23
Note If the previous shutdown was resulted from termination of battery discharge because of Utility failure, the automatic function will be activated when the Utility restores. 2, After the system is started up properly , apply the load gradually and monitor the load condition through LCD, as shown in Figure 3-8: 3, In the event of load exceeding the rated capacity of the UPS, of 105% load , the buzzer will beep every 0.5 second with corresponding load percentage indication .
Chapter 3 Operation 1. Press and hold the ON/SILENCE button for about 1 second, after a beep and system self-test, the battery indicator and inverter indicator turns green, as shown in Fig. 3-9, and the buzzer beeps every 3 seconds, indicating the UPS is operating in Battery mode.
Note After battery test, the battery state information will be refreshed. In the event of battery fault due to the battery not bang fully charged is detected during test, user may re-test the battery after fully charging it to confirm that the fault is removed. 3.2.4 Turn off the Inverter 1.
If the battery backup time is found noticeably shortened, or when the UPS LCD displays "BATTERY FAIL", please contact the Liebert or its authoriged agent to confirm whether the battery needs to be replaced. Before replacement, please make sure that the specifications of the new batteries are correct.
Chapter 4 Maintenance and Storage Notice 1. Never short-circuit the battery terminals, which may result in fire. 2. Never open the battery, as the electrolyte is harmful to human body. In the event of inadvertent contact of electrolyte, immediately rinse it off with water and go to hospital for treatment .
