AC POWER DISTRIBUTION
Two main busbars XS 1 and XS 2 and an essential busbar XE are provided. During normal operation,
busbars XS 1 and XE are fed by No. 1 inverter and XS 2 by No. 2 inverter.
In the event of a single main inverter failure, the remaining main inverter output will be automatically
switched to supply all three busbars. If failure of both main inverters should occur, essential services
supplied from busbar XE will be maintained by the standby inverter.
