Possible cause
The UPS internal heat sink
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 2°C, the UPS
transfers to bypass mode or
standby mode.
UPS was manually
commanded to switch to
bypass and will remain in
bypass until commanded out
of bypass.
The UPS is on bypass while
operating on the high
efficiency setting.
Site fault detection is
supported on all models any
time there is a grounding
neutral connection. Alarm
triggers when the difference
between ground and neutral
voltage is >15 V.
UPS has an unexpected
bypass current on battery
mode.
UPS has transferred to
bypass or fault mode
because of overload in
inverter mode.
UPS has cut off the output
and transferred to fault
mode because of overload in
bypass mode or HE mode.
Indicates that the UPS has
detected abnormally low
impedance placed on its
output and considers it a
short circuit.
Indicates that the fan could
not work normally.
Remedy
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.
Check the maintenance
bypass switch status.
The equipment transferred
to bypass utility power as a
normal function of high
efficiency operation. Battery
mode is available and your
equipment is protected.
Site fault detection should be
enabled by default. It can still
be enabled / disabled from
the LCD settings menu.
Reconnect all input wires.
Transfer to maintenance
bypass and call service.
The UPS transfers to battery
mode if supporting the load.
Remove some of the
equipment from the UPS.
Remove some of the
equipment from the UPS.
Remove all the loads. Turn off
the UPS. Check if UPS output
and load has short circuit.
Ensure short circuit is
removed before turning on
again.
Check fans of UPS.
