SYMPTOM
The AC output shuts down completely.
The red overload LED is lighted.
The green LED is off
Buzzer alarm is sounded.
Red Over Temp LED is on.
There is no AC output
POSSIBLE CAUSE
Permanent shut-down of the AC output
due to continuous overload beyond the
continuous power rating of the inverter.
Permanent shut-down of the AC output
by the GFCI due to leakage > 5mA as a
result of ground fault
Shut-down due to over temperature
because of fan failure or inadequate
cooling as a result of high ambient
temperature or insufficient air exchange
REMEDY
1. Reduce the load
2. The load is not suitable as it requires
higher power to operate. Use an
inverter with higher power rating.
3. If the unit goes into permanent
overload again after resetting and
removing the load completely, the unit
has become defective. Call Technical
support.
1. Check for ground fault in the load
circuit. ( A ground fault will cause a
minor shock on touching.)
Note:
In both the cases, the unit will be
latched in this shut-down condition. To
reset, switch the power on / off switch
to off and then on again. Before
switching on again, remove the cause of
the shut-down
1. Check that the fans are working. If
not, the fan / fan control circuit may be
defective. Call Technical Support.
2. If the fans are working, check that
the ventilation slots on the suction side
and the openings on the discharge side
of the fan are not obstructed.
3. If the fans are working and the
openings are not obstructed, check that
enough cool replacement air is
available. Also check that the ambient
air temperature is less than 40º C
4. Reduce the load to reduce the
heating effect.
5. After the cause of over heating is
removed and the unit cools down, it
will reset automatically
