Chapter 3 Operation 19 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 power from rectifier; meanwhile, the charger 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. OUTPUT VOLT 220.
Chapter 3 Operation OUTPUT VOLT 215.0V Figure 3-2 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.
Chapter 3 Operation 21 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. For the load equipment which is less critical , users can select ECO mode to power the equipment to reduce the power consuming.
Chapter 3 Operation OUTPUT VOLT 215.0V Figure 3-5 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.
Chapter 3 Operation 23 OUTPUT VOLT 220.0V Figure 3-7 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: LOAD 70.0% 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.
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. OUTPUT VOLT 220.0V Figure 3-9 2. Overload process is same with the above "Start from the utility power".
Chapter 3 Operation 25 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.
Chapter 4 Maintenance and Storage 27 Chapter 4 Maintenance and Storage I. Battery Maintenance The internal battery of GXT2-3X1 series UPS is sealed, lead-acid, maintenance-free battery. The battery life depends on the ambient temperature, charge and discharge cycles . High ambient temperature and deep discharge can shorten battery life. To ensure battery life, the battery should be maintained regularly: Keep the ambient temperature between 15℃ and 25℃.
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 . II. Keep Air Vent Unblocked 1. Regularly clean the system, especially the air inlet and air outlet. Make sure the air flows freely inside the chassis. Use vacuum cleaner for cleaning when necessary.
Chapter 5 Handling Abnormal Problem 29 Chapter 5 Troubleshooting In the event of UPS fault, please check and remove the fault immediately following the methods described in the table below. If the fault persist , please contact Liebert or its authoriged agents. Sequence No. Phenomena Description 1 No panel display and system self-test when the Utility switch is in the ON position. A. Utility hasn't been introduced into the system; B. Input undervoltage.
Chapter 5 Handling Abnormal Problem Sequence No. Phenomena Description Cause Action 9 The UPS has reduced A. The battery is not battery time. fully charged; B. The battery is not able to hold a full charge due to age. A. Allow the battery to charge for more than 8 hours when the Utility is normal, and then re-test the discharge time; B. The battery needs replacement, please contact the Liebert or its authoriged agent. .
