Functional explanation
•
12V light fitted with 13-pin plug as standard
(8 pins assigned).
•
Your towing vehicle may be fitted with a 7-pin or a 13-pin
socket.
•
To make the electric system of your towing vehicle
compatible with the trailer, you can use an adapter if
required.
Pay attention to the respective installation instructions
for the adapter plug.
The plug is pre-assembled according to standard
DIN ISO 1724. Making independent modifications to the
contact assignment may impair the function of the
lighting system.
►
Have qualified specialist personnel check any retrospec-
tive modifications made to the plug connection on your
trailer.
It can only be warranted that the lighting system will
work perfectly if the contacts are clean / not deformed
and not worn.
WARNING
Damaged / torn cable!
Damaged, torn, worn or porous cable can impair the function or
even cause the lighting system to fail, posing an indirect risk of
accident during operation.
►
Before setting off and when parking, check that the cables
are properly fed through to the drawbar (without any
extreme bends).
►
Do not leave the cable on the ground when parking - care-
fully wind it around the drawbar.
►
Do not pull on the cable itself - only pull on the plug.
►
Regularly check the cable and its routing under / on the
chassis / drawbar for damage and wear.
►
Do not tow the trailer if the cables are torn or porous.
Have a specialist workshop repair or completely replace
them immediately.
►
Never try to repair damaged cable yourself.
►
If necessary, replace missing cable clips / ties.
►
Maintain the electric cabling as required with a damp
cloth and silicone spray.
If you have any problems with the electric system,
contact your car dealer or a specialist workshop before
working on the electrical system.
Humbaur GmbH will not accept any liability or costs
for consequential damage to the electric system on the
towing vehicle and / or the trailer caused by incorrect
configuration or reconfiguration of the contacts on the
plug.
