Battery Operation
During battery operation, the load is supported by the inverters. The inverters are supplied by battery
power, ensuring uninterrupted support to the load.
While the UPS is running in battery operation, a single-line diagram will appear on the screen with a
green line indicating the power flow from the batteries through the main inverter to the load for as
long as the batteries are energized.
CAUTION!
Do not open Q2, Q7 or Q8 when the UPS is in battery operation, as this action may result
in a load drop or a failure of the UPS to support the load.
