  • Page 29: Battery Mode

    Battery Mode The UPS transfers to Battery mode automatically if the main AC source is abnormal, for example, when unstable voltage or a power outage occurs. In Battery mode, the batteries provide DC power and the UPS converts it into AC power and supplies it to the connected critical loads via the Output Switch (Q4).

  • Page 30: Manual Bypass Mode

    Manual Bypass Mode When the UPS works in Manual bypass mode, the current flows through the maintenance bypass instead of the power modules so that the maintenance personnel can maintain the circuit inside the UPS. However, DO NOT touch any terminal block which may carry high- voltage electricity.

  • Page 31: Frequency Conversion Mode

    Frequency Conversion Mode NOTE: Frequency Conversion mode is only applicable to single UPS but not to parallel UPSs. After the UPS is manually set as Frequency Conversion mode via the LCD, the inverter will automatically select 50Hz or 60Hz as the fixed output frequency. After the output frequency is determined, the system will automatically disable the bypass function.
