No output power

Possible cause and remedy: 

• The power inverter is not fully warmed up.

Switch the power inverter on and off again until
the device attached to the power inverter is
supplied with power. Repeat this process in order
to switch the device on.

• The ignition must be switched on for the 12 V in

vehicle receptacle to be supplied with power. 
Switch the ignition on and/or in the position I.

• The power inverter is overloaded. Reduce the

load until you no longer exceed the maximum
load as specified in the technical data.

• The power inverter is overheated. Wait until the

device has cooled down. Ensure that there is
sufficient ventilation space. Make sure that the
connected load does not continually exceed the
maximum load, in order to avoid overheating
again.

• The device fuse is burnt out. Consult the service

department in order to put the device back into
working condition. Make sure that the power in-
verter is connected to the power supply with the
correct polarity.

Cleaning

Risk of potentially fatal electrical
shock:

• Never submerse the device in water or other 

liquids!

• Do not allow any liquids to penetrate the

housing.

• Before every cleaning remove the power in-

verter from the 12 V vehicle receptacle. Also
remove any devices connected to the power
inverter.

Cleaning the housing:

Clean the housing surface with a slightly damp
cloth Never use benzene, solvents or detergents
that can damage plastics!
In the event that the ventilation slots become dusty
you can clean these with a soft brush.
