Troubleshooting

Alarm and events indicate warnings and notify of errors or potential failures in the
system. The output of the UPS is not necessarily affected in case of an alarm but
taking the correct actions may prevent loss of power to the load. If the UPS system
does not operate correctly, attempt to solve the problem using the table below.
Alarm or Event
Utility Abnormal
Alarm Code: 02
Site Wiring Fault
Alarm Code: 04
Battery Disconnect
Alarm Code:11
Battery low
Alarm Code:12
Service Battery
Alarm Code:13
Charger Fail
Alarm Code:15
Battery Over Voltage
Alarm Code:16
BUS Over Voltage
Alarm Code:21
BUS Under Voltage
Alarm Code:22
BUS Unbalance
Alarm Code:23
Possible cause
The input mains is out of the UPS
tolerance range
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.
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.
The UPS is in battery-mode and the
battery autonomy is running low.
A battery string failure has been
detected and the battery charger has
been disabled until its replacement
Indicates a charger failure
Indicates that the battery voltage is
too high
Indicates an over voltage in the BUS
of the UPS.
Indicates an under voltage in the
BUS of the UPS.
Indicates that the positive BUS
voltage and negative BUS voltage
are not symmetric
Remedy
Check input mains condition
Site Fault detection should be
enabled by default. It can be enabled
/ disabled from the LCD settings
menu.
Reconnect all input wires
Verify that all batteries are properly
connected.
If the condition persists, contact your
service representative.
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
Contact your service representative
The UPS charger is turned off until
the next startup. Contact your
service representative
The UPS will turn off the charger until
the battery voltage is normal
The UPS transfers to Bypass-mode
