Alarm
type
Code Icon Possible cause Remedy
Fault 01
The internal converter failed, so the
DC bus voltage could not be
boosted correctly. Contact the dealer for repair
Fault 02
1) The mains input or load
transient current cause the DC
bus voltage too high.
2) The internal converter failed.
1) Shut down and restart the UPS to
see if it happens again. If the
problem
still persists, please
contact the dealer for repair.
2) Contact the dealer for repair.
Fault 03 The internal converter fails, so the
DC bus voltage is too low. Contact the dealer for repair.
Fault 04 1) The load is special or abnormal,
so the internal positive and
negative DC bus voltages are
unbalanced;
2) The internal converter failed.
Contact the dealer.
Fault 11
The internal inverter fails, so the
inverter voltage could not start up
correctly. Contact the dealer for repair.
Fault 12 The internal inverter fails, so the
inverter voltage is too high. Contact the dealer for repair.
Fault 13 The internal inverter fails, so the
inverter voltage is too low. Contact the dealer for repair.
Fault 14
Short circuit occurs on the UPS
output.
Remove short circuited output/situation.
If the problem still persists, please
contact the dealer for repair.
Fault 1A
UPS output power is negative. It
means there is energy feedback
into the internal of UPS from output.
It may be caused by regenerative
load or the current control failure in
the parallel system. Contact the dealer.
Fault 21
The internal battery SCR failed and
short circuited. Contact the dealer for repair.
Fault 2A
Short circuit occurs on the charger
output. Remove short circuited
output/situation. If the problem still
persists, please contact the dealer for
repair.
Fault 24 The internal inverter relay is stick to
short circuited or the SCR of STS
(Static
Transfer Switch) is
short-circuited.
Contact the dealer for repair.
Fault 41 The internal temperature is too high
and
reaches the fault level
(shutdown point):
1) Maybe the environment is hot.
2) Maybe the fan is blocked or
failed.
3) Maybe the ventilation is blocked
by the wall or other goods.
4) Overload
1) Make sure the ambient
temperature not over 40
º
C;
2) Make sure the fan is OK;
3) Make sure the ventilation is well;
4) Remove some loads if possible.
Fault 42
Internal communication between
the CPUs failed Contact the dealer for repair.
Fault 43
Overload times are out of the
specification and the UPS shuts
down automatically. Remove excess loads from UPS
output and restart it.
