Troubleshooting
Check AC Input Source and
make sure it is correct and
powered on. Make sure input
circuit breaker (external to
UPS) is turned on. Make sure
the front panel RCD is
properly plugged in the front
of the UPS. If UPS is still
turned off and appears dead,
call Eaton Service.
Press the On/Off switch in
front of the UPS for at least 3
seconds Make sure REPO is
not activated at the rear panel
of the UPS
Turn on the DC Breaker on the
UPS rear panel If this is a UPS
without internal batteries,
then make sure that there is
an EBM (External Battery
Module) connected to the
UPS. Turn on the DC Breaker
on the EBM. Clear any active
alarms via the RCD.
Shut the UPS off – both the
AC input and the DC Breaker
on the UPS need to be turned
off. Check the AC input wiring
– to make sure Line and
Neutral have not been
reversed
Turn on the DC Breaker on the
UPS' rear panel. If this is a
UPS without internal
batteries, make sure that an
EBM is connected to the UPS
