    I am reviewing an Eaton 9390 UPS,the input power line is three phase 440volt.

    When Ups is switched on an phase of input drops to 52 volt (L2) and the ups not emit any type  of error.

    The measurements were made between phase and ground. 

    The other two phases do not present problems.

    I would appreciate someone  who has experience with these model can tell me possible causes of the failure
