At this moment, the operation of switching the inverter output into the maintenance bypass has
been completed. The load is driven by the maintenance bypass, the entire fans stops and the
Energy Sever is shut down completely. However, the voltage of the DC BUS inside the Energy Sever
is still high. Once the DC BUS is discharged completely, the maintenance personnel can take the
routine maintenance or repair for Energy Sever. In maintenance mode, loaded devices have no AC
power abnormal protection.
5.4.3 Exit Service Mode:
After the maintenance work is completed, the following procedures can be executed to switch the
load from the non-AC power supply abnormal protection status to the inverter power supply
protection status.
