Alarm or Event
Possible cause
Remedy
Utility Abnormal
Alarm Code: 02
The input mains is out of the UPS tolerance
range
Check input mains condition
Site Wiring Fault
Alarm Code: 04
Site Fault detection is supported on all-models
when a Grounding Neutral connection is
present. Alarm will trigger when the difference
between ground and neutral voltage is >15V.
Site Fault detection should be enabled by
default. It can still be enabled / disabled from
the LCD settings menu.
Reconnect all input wires
Battery Disconnect
Alarm Code:11
Battery voltage is lower than the batteries
disconnected level defined for this UPS. There
could be a blown fuse, intermittent battery
connection or disconnected battery cable.
Verify that all batteries are properly connected.
If the condition persists, contact your service
representative.
Battery low
Alarm Code:12
The UPS is in Battery-mode and the battery
autonomy is running low.
This warning is approximate and the actual
time to shut down may vary.
Depending on the UPS load and the number of
External Battery Modules (EXBAT), the
“Battery Low” warning may occur before the
batteries reach 25% capacity
Service Battery
Alarm Code:13
A battery string failure has been detected and
the battery charger has been disabled until its
replacement
Contact your service representative
Charger Fail
Alarm Code:15
Indicates a charger failure
The UPS charger is turned off until the next
startup. Contact your service representative
Battery Over Voltage
Alarm Code:16
Indicates that the battery voltage is too high
The UPS will turn off the charger until the
battery voltage is normal
BUS Over Voltage
Alarm Code:21
Indicates an over voltage in the BUS of the
UPS.
The UPS transfers to Bypass-mode if
supporting the load
BUS Under Voltage
Alarm Code:22
Indicates an under voltage in the BUS of the
UPS.
The UPS transfers to Bypass-mode if
supporting the load
BUS Unbalance
Alarm Code:23
Indicates that the positive BUS voltage and
negative BUS voltage are not symmetric
The UPS transfers to Bypass-mode if
supporting the load
BUS Short
Alarm Code:24
Indicates that the BUS voltage decreases very
fast
Contact your service representative
BUS Softstart Fail
Alarm Code:25
Indicates that the BUS could not perform a soft
start successfully
Contact your service representative
Output Short Circuit
Alarm Code:31
Indicates that the UPS has detected
abnormally low impedance placed on its output
(considered as a short circuit)
Remove all the loads. Turn off the UPS.
Check if UPS output and loads are short
circuited.
Ensure short circuits are removed before
turning the UPS on again.
Inv Over Voltage
Alarm Code:32
Indicates an inverter over voltage
The UPS transfers to Bypass-mode if
supporting the load
Inv Under Voltage
Alarm Code:33
Indicates an inverter under voltage
The UPS transfers to Bypass-mode if
supporting the load
Inv Softstart Fail
Alarm Code:34
Indicates that the inverter could not perform a
soft start successfully
Contact your service representative
Output Overload
Alarm Code:41
Output is in overload.
Remove some of the load from the UPS. The
UPS continues to operate, but may switch to
Bypass-mode or shutdown if the load
increases.
The alarm resets when the condition becomes
inactive.
Inv Overload Fault
Alarm Code:42
UPS has been transferred to bypass or fault-
mode caused by a high overload in inverter-
mode
The UPS transfers to Battery-mode if
supporting the load. Remove some of the load
from the UPS
Byp Overload Fault
Alarm Code:43
UPS has cut off the output and transferred to
fault-mode because of overload in bypass-
mode or HE-mode.
Remove some of the load from the UPS
Battery-mode
Alarm Code: 62
A utility failure has occurred and the UPS is on
Battery-mode.
The UPS is running in battery-mode. Prepare
your equipment for shutdown.
Eco-mode
Alarm Code: 63
The UPS is on bypass while operating on the
High Efficiency setting.
The equipment operated in bypass as
standard when in High Efficiency operation.
Battery-mode is available and your equipment
is protected.
EPO Active
Alarm Code: 71
The external contacts in the rear of the UPS
are configured for EPO operation and they
have been activated.
Check the EPO connector status
