Location 

The DC/AC converter control unit in model 204.9 is located in the trunk behind the right luggage compartment lining.

On model 204.0 the DC/AC converter control unit is located in the center console under the trim.

Task 

The DC/AC converter control unit converts the DC voltage of the on-board electrical system into a 115 V AC voltage. The 115 V (X58/34) power outlet enables small electrical devices to be connected that require an AC voltage (e.g. video games consoles, cell phone chargers). The maximum available electrical continuous load is P = 150 W, for a short-term up to P = 300 W is permissible for t = 2 s.

The rear SAM control unit with fuse and relay module (N10/2) supplies power to the microswitch power outlet (X58/34s1) in the 115 V power outlet. If a consumer is now connected to the 115 V power outlet, this voltage is switched through to the control input for the DC/AC converter control unit.
