Eaton 9140 UPS (7.5–10 kVA) User's Guide
Possible Cause
The UPS is in Bypass mode.
Bypass is not available because the
bypass input utility is outside the
configured bypass range.
The UPS does not recognize the
internal batteries.
A battery tray is disconnected.
Power requirements exceed the
UPS capacity (greater than 100% of
nominal; see page 92 for specific
output overload ranges).
The UPS internal temperature is too
high or a fan has failed.
Ground wire connection does not
exist, or the line and neutral wires
are reversed in the wall outlet.
Input is phase to phase (neutral is
not bonded to ground).
The batteries need charging or
service.

Action
The equipment transferred to bypass utility
power. Battery mode is not available; however,
the utility power continues to be passively
filtered by the UPS. Check for one of the
following alarms: overtemperature, overload,
UPS failure, hot swap, or remote emergency
power-off (REPO).
Check the bypass utility. The UPS is receiving
bypass utility power that may be unstable or in
brownout conditions. The UPS continues to
supply power to your equipment. Check for one
of the following alarms: bypass over or under
voltage, bypass over or under frequency, or
bypass unavailable.
If the condition persists, contact your service
representative.
Verify that all battery trays are fully seated and
locked in place. If the condition persists,
contact your service representative.
Remove some of the equipment from the UPS.
The UPS continues to operate, but may switch
to Bypass mode if the load increases. The alarm
resets when the condition becomes inactive.
Shut down the UPS. Clear vents and remove any
heat sources. Allow the UPS to cool. Ensure the
airflow around the UPS is not restricted. Restart
the UPS. If the condition persists, contact your
service representative.
Have a qualified electrician correct the wiring.
Disable the Set Site (Wiring) Fault setting (see
User Settings table on page 64).
Apply utility power for 48 hours to charge the
batteries. If the condition persists, contact your
service representative.
