MGE Galaxy 60Kva Parallel UPS shutdown PFC

[BillP]

Dear All,

Our existing MGE Galaxy 60Kva Parallel UPS shutdown last night reporting PFC fault.
We are facing challenges with PFC Fault (logs read; PFC out of order), can any one share ideas on how to diagnose or what to do to fix this fault.

Best Regards,
