Action Possible Cause Alarm or Condition
Bypass UPS is in Bypass mode. The equipment is transferred to utility power; however,
the utility power continues to be passively filtered by the
UPS. Check for one of the following alarms:
Overtemperature, Overload, or UPS Failure.
The UPS automatically returns online after the condition
is cleared. However, if the UPS transfers to Bypass mode
3 times in 1 hour, the UPS remains in Bypass mode until
the UPS On
| button is pressed or the 1-hour timer
expires.
NOTE If Bypass mode is due to a UPS failure, frequency
conversion (FC) UPS models no longer convert the utility
frequency to the load.
Bypass
Bypass is not available. Input
voltage is not within ±12% of
nominal or input frequency is
not within ±3% of nominal. The UPS is receiving utility power that may be unstable or
in brownout conditions. The UPS continues to supply
power to your equipment. If conditions worsen, the UPS
may switch to battery power.
Battery Service
The battery may be fully
discharged. Plug the UPS into a power outlet (apply utility power on
hardwired models) for 24 hours to charge the battery.
After charging the battery, press and hold the
button
for 3 seconds; then check the indicator.
If the indicator is still on, see “UPS Maintenance” on
page 41 to replace the battery.
The battery is not connected
correctly or the battery
circuit breaker is open. Verify that the internal batteries are installed correctly
(see page 16) and that the battery circuit breaker is in the
ON (
| ) position. Call your service representative if the
problem persists.
Site Wiring Fault
(North American
models only) Ground wire connection does
not exist or the line and
neutral wires are reversed in
the wall outlet. Have a qualified electrician correct the wiring.
To disable this alarm, see “Configuration” on page 35.
Overtemperature
UPS internal temperature is
too high. The UPS switches to
Bypass, allowing the UPS to
cool. Clear vents and remove any heat sources. Ensure the
airflow around the UPS is not restricted. If the condition
persists, contact your service representative.
Overload
Continuous audible alarm
Power requirements exceed
UPS capacity (103–112% for
2 minutes; 112–150% for up to
30 seconds) or the load is
defective. Remove some of the equipment from the UPS.
If the overload condition persists, the UPS automatically
shuts down.
