American Power Conversion Bypass Static manual Battery Operation

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.
