Power Xpert 9395 UPS (450–550 kVA) Installation and Operation Manual
If at any time during the battery discharge the input power becomes available again,
contactors K1 and K5 close and the rectifier begins to supply DC current to the
converter and inverter. At this point, the unit returns to Normal mode. Depending on
the total load and the duration of the battery discharge, battery current limit alarms
may be seen for a short time due to the current required to recharge the battery.
The system oneline drawings in this section show the simplified internal structure of
the UPS, battery supply, and basic maintenance bypass.
