Additional information for 13-pin plug configuration
9* Continuous current
Under no circumstances clamp contact no. 10 to contact
no. 9 in the plug.
This could cause damage to the towing vehicle or the
control electronics in the towing vehicle.
This contact is
not
configured in the plug!
The contact is only configured on the car socket if the car
coupling is supplied with the car.
10* Charging lead
Only use contacts no. 10 and 11 for the charging current
- according to DIN ISO 11446.
Normally this contact is
not
configured in the car
socket!
If these are not already installed/connected in the connector
of the towing vehicle, the appropriate connections must be
fitted.
The charging lead should be connected to the battery via an
isolating relay as soon as the ignition is switched on and the
engine is running.
11* Ground electric circuit for charging lead
Under no circumstance connect contact no. 11 (ground
charging current) to contact no. 13 (ground continuous
current).
Normally this contact is
not
configured in the car
socket!
The two earthing wires must be insulated on the trailer side.
Trickle charge
Towing vehicles without a socket according to DIN
ISO 11446 do not normally have a cut-off relay.
The result of this is: Damage to the car starter
battery or electronics as well as deep discharge of the
starter battery.
If the charging line is connected correctly according to
DIN ISO 11446, then the supply battery of the trailer that is
connected via the charging line to the 13-pin socket on the
towing vehicle is kept charged.
Please note this is primarily a trickle charge and not a full
charge of the supply battery.
If only short distances are travelled, the charging time
may not be enough for a trickle charge.
The cross-sections the cables in most towing vehicles
(cars) are too small to completely charge the supply battery.
The output of the alternator is usually insufficient to fully
charge an additional supply battery in the trailer.

NOTICE
Discharged / low trailer battery!
The trailer battery can cause faulty motor-starting relays in
the towing vehicle.
Check the power of the battery at regular intervals.
Fully charge the battery via an external battery charger.
Maintain the power of the battery via a trickle charge in
the event of prolonged disuse.
Check the charge status of the battery e.g. with a Battery
Guard (Fig. 14 /1).
Connect the contacts to the positive / negative terminal
of the battery.
Download the “IntAct Battery-Guard“ app on your
smartphone.
Check the charge status by means of Bluetooth.
