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
unvailable.
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.
Apply utility power for 48 hours to charge the
batteries. If the condition persists, contact your
service representative.
Supply power to the connected equipment: Turn
the UPS on by selecting MENU from the system
status screen, then select CONTROL, OUTPUT
CONTROL, UPS TO ONLINE, and OK to confirm.
