Operating manual

Connecting the power inverter

Note:

 Only allow suitably trained and qua-

lified  people  to  install  the  power  inverter. 

First Wise Media GmbH accepts no liability 

whatsoever for any damage that is caused 

or injuries that are sustained as a result of 

an incorrect installation.

 

Make sure the On/Off switch on the 

power inverter is set to 

Off

 and that the 

vehicle’s ignition is off.

 

Connect both cables according to their 

colours to the power inverter.  

 

Watch the polarity when connecting to 

the car’s power supply: 

  (+12V) red, (earth) black

 

Connection should be made only to a 

fused section of the car’s power supply. 

If connecting the power inverter directly 

to the car’s battery, then an additional 

fuse should be integrated to prevent 

short-circuits in the circuit. If this is the 

case then cut the red (+) cable in two 

directly behind the battery and fit a 40A 

fuse. This fuse is not included, but is 

available as a vehicle accessory.

 

When installing, make sure that the 

power inverter and the wiring is not 

installed near safety systems like airbags 

or belt pretensioners etc. and that it 

does not interfere in any way with such 

systems.
