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 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 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
