IMPORTANT
Before Switching ON Or Switching OFF the Inverter, Switch off all the loads at the ouput
.
TROUBLE SHOOTING CHART
PROBLEM
PROBABLE CAUSE
REMEDY
DC Fuse Fail
A.Skin effect due to prolong use
B.Short Circuit on Excessive overload
on Inverter
A.Replace Fuse
B.Check the inverter o/p for
excessive over loading. Reduce the
load to the limit and check the
inverter.
DC under voltage comes immediately
after the inverter is switch ON ( No
load) and Inverter Trips
A.DC input cable is less than the rated
capacity
B.Loose contact in output Line
A.Replace the cable, use the cable
of proper rating
B.Tighten all the connections
DC under voltage indication comes
on when working on battery and
Inverter Trips.
A.Battery is Discharged.
B.Battery cable is of lesser capacity
than rated.
A.Keep the battery in charged
Condition
B.Replace the cable with a rated
ampere cable.
Inverter Not getting ON
A.Break in the DC supply either due to
blown fuse or disconnected wire.
B.Control Card not receiving the DC
supply or same wire got de-soldered.
C.Control Card Defective
A.Replace Fuse or Check wiring as
necessary.
B.Check Inverter fuse and replace if
found faulty or check control wiring
as may be required.
C. Replace control card
Over load LED Flashing with no
output
A.Feed back fail
B.Short Circuit
A.Check feedback transformer or
break in wiring of transformer.
B.Remove the load and see the
short circuit removed, there may
Inverter trips before loaded fully. Over load trip setting not proper
Set Overload tripping by means of
adjusting the Potentiometer of
inverter card.
Check Power requirement of the
load. Switch on the load one by
one after the output voltage
reaches 230V
