    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.

  • Page 20: Battery Mode

    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.

  • Page 21: Eco Mode

    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.
