Prompts and meanings
Prompt
Meaning
Transfer with interrupt, confirm or
cancel
The inverter and bypass supplies are not synchronized and any load transfer
between the inverters and bypass will cause a brief load interruption
The load is too high to be transferred
with interrupt
The total load must be less than the capacity of one UPS to allow a parallel
system to perform an interrupted transfer from bypass to inverter
This operation leads to output
shutdown, confirm or cancel
The bypass is abnormal, turning off the inverters will cause the load to be
de-energised
