2.4   Instructions for the electrical connection

The Dometic generator is a source of alternate 230V 50Hz tension, 

able to cope with various power needs. 

Electrical connection to the external network

The on board electrical system must be fitted with a relay or switch (e.g. 

Dometic switch cod. AG113, available on request) to prevent damage 

to the generator when the external power supply network is connected; 

in this case, it is suggested that the generator be connected in such a 

way as to give it priority with respect to the external network.

Electric wiring must be effected in conformity with the existing laws and 

regulations in force in the user’s country.

For  correct  installation  performed  by  the  final  user,  use  preventive 

technical assistance by your seller or by a skilled technician. 

For the 230 V, use an approved cable with the section indicated in the 

table. For connection of the Dometic switch cod. AG113 refer to the 

instructions and diagram on the following pages.

 Electrical connection of the battery charger

The unit is set up to provide for automatic battery recharging. If this 

function is to be used, proceed as follows.

Use a cable finding the correct section in the chart on the right. 

Connect the cable to the connecting terminal and to the positive pole 

of the battery to be charged.

Should the battery be others than that used to start the generator, then 

connect the negative pole of this battery to the proper mass point of the 

generator (see picture on page 17).

NB:

The negative pole of the battery should be grounded with the 

vehicle’s frame.

Connecting the fuel indicator

Only use the indicator connection if there is a fuel level probe in the 
tank used for the generator. Connect the proble cable (e.g. float) to the 
relevant terminal (see figure above).
