4 Troubleshooting guide:

Common problems – television interference:
Operation of the power inverter can interfere with television reception on some channels, If
this situation occurs, the following steps may help to alleviate the problems.
Make sure that the chassis ground lug on the back of the power inverter is solidly
l
connected to the ground system of your vehicle, boat or home.
Do not operate high power loads with the power inverter while watching television.
l
Make sure that the antenna feeding your television provides an adequate (" snow
l
free") signal and that you are using good quality cable between the antenna and the
television.
Move the television as far away from the power inverter as possible.
l
Keep the cables between the battery and the power inverter as short as possible and
l
twist them together about 2 to 3 twists per foot.
This mini radiated interference from the cables.

WARNING!
Do not open or disassemble the inverter. Attempting to service the
unit yourself may result in a risk of electrical shock or fire.
Possible Cause
Using average reading
voltmeter
Overload
Low / High input voltage.
Thermal shutdown
Short circuit or wiring error. Check AC wiring
Very high power load
Solution
Use true RMS reading meter
and cable
(Ref. point 2-4-7)
Reduce load.
Recharge battery,
check connections
and cable. (Ref. point 2-7-1)
Improve ventilation
Make sure ventilation
openings in inverter
are not obstructed,
reduce ambient
temperature.
for short circuit or
improper polarity (hot
and neutral reversed)
Remove load
