Troubleshooting
Fault Cause
Remedy
No output voltage
No contact to the battery
Check contact and cable. Switch On the ignition if
necessary.
INC150N/ INV150N/ INV300N/ INV600N: check the 12V
socket and replace it if necessary.
Overheating
Switch off power consuming devices
Let the inverter cool down and ensure better ventilation.
Defective fuse (in the
Cigarette plug, inverter, or
The vehicle)
Replacing the fuse with one of the same specification.
Device defective
Replace the device.
Interference From
TV
set/audio
systems and / or other
external appliances
operation
snow image, image not
steady
humming, booming and
whirring sound audible.
Place power inverter as far away from TV set as possible,
check aerial connection and setting. Place aerial cable
away from power inverter. Use a shielded aerial cable.
The modified sine wave of the power inverter cannot be
filtered sufficiently by the connected external appliance.
disconnect all cables immediately. The only available
solution is to use a more modern external appliance or
one with a higher rating with adequate filtering capability.
The device
switches On and
off repeatedly
Excessive constant load
Reduce the load.
