Important notes

Danger of damage to the vehicle's electronic system. Data which are stored
electronically may get lost.

Use a closed-circuit current conservation unit if necessary.
Note
During installation, special attention has to be paid to the following points:
•
Cables may not be pinched or damaged.
•
All sealing elements have to be installed properly.
•
The socket gasket has to be positioned on the insulating sleeve and not on the individual
wires.
•
Lay the cables such that they do not rub on the vehicle and are not bent.
•
Do not lay any cables near the exhaust system.
•
Install the controller such that it is protected against the intrusion of moisture. The cable
connection should always face downward.
When a trailer is used, the rear fog lamp of the traction vehicle is deactivated.
In the case of trailers without rear fog lamps, a rear fog lamp has to be retrofitted.
Use a corresponding adapter to adapt the system to a 7-pin trailer socket. The adapter is
available in specialist shops under the Westfalia part no. 300 100 320 113.
An electrical socket adapter may only be used in conjunction with a trailer. Remove the socket
adapter when the trailer is no longer used.
Correct trailer operation has to be checked using a trailer or a test instrument with load resistors.
