The UPS internal temperature is
too high or a fan has failed.
At the warning level, the UPS
generates the alarm but remains
in the current operating state.
If the temperature rises another
10°C, the UPS transfers to Bypass
mode or shuts down if Bypass is
unusable.
The input source is not connected
correctly.
The Remote Power Off (RPO)
switch is active or the RPO
connector is missing.
Input/Output cables are not
connected to the correct terminal
blocks.
10. Troubleshooting
If the UPS transferred to Bypass
mode, the UPS will return to normal
operation when the temperature drops
5°C below the warning level.
If the condition persists, 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 continues to persist,
contact your service representative.
Check the input connections.
If the UPS Status menu displays the
"Remote Power Off" notice, inactivate
the RPO input.
Connect correctly the Input/Output
cables.
