If the UPS malfunctions during operation please check that all lines are connected properly and that the
utility specifications are correct. Refer to the table below to troubleshoot. Should the problem persist
please contact your local dealer for assistance.
Situation Check Items Solution
Fault LED
Read the error code (see next page)
displayed by the combination of LEDs,
and verify the fault as follows.

Check the battery connection.
Measure battery voltage to ensure
that batteries are charged and
healthy. Recharge batteries for 8
hours if necessary. Simulate utility
outage to verify that UPS is able
to provide DC backup. Otherwise
consult your local dealer right away.
Overload
Disconnect some non-critical loads
from the UPS output until the
overload ceases. Check if there is any
short circuit between cables due to
broken cable insulation. Replace the
cables if necessary.

Remove any objects obstructing the
ventilation louvers. Verify that the
cooling fans are working properly.
Contact your local dealer to replace
the fans if necessary.

Check if the “L” and “N” phases of the
utility AC source have been wrongly
wired or if the Ground-Neutral
voltage exceeds the limits.

Verify that the ventilating fans are
functioning properly.
Do not attempt to replace the fans
yourself. Contact your local dealer for
replacement.
Other error codes
