If at any time during the battery discharge the input power becomes available again,
the rectifier begins to supply DC current to the inverter. At this point, the UPS returns
to Normal mode. If at any time during the battery discharge the AC input power
becomes available again, each rectifier turns on, assumes the inverter load from the
batteries, and begins recharging the batteries. Depending on the total load and the
duration of the battery discharge, battery and rectifier input current limit alarms may
be seen for a short time due to the current required to recharge the batteries.

Multiple UPS Distributed Bypass System Oneline Configurations
The distributed bypass system oneline drawings in this section show the simplified
internal structure of the UPS, battery supply, and basic maintenance bypass in a
multiple UPS configuration. These onelines do not show each UPM in the UPSs, but
represent each UPS in the distributed bypass system. The following voltages apply:
380V, 400V, 415V, and 480V.
