Remove some of the equipment from

may switch to Bypass mode or shut
down if the load increases.

becomes inactive.
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.

for at least 1 second, until the front
panel displays "UPS starting...".
Check the power cord connections.
If the UPS Status menu displays the
"Remote Power Off" notice, inactivate
the RPO input.

into the UPS receptacles.
