WA 1208 Operating and
Installation Instructions
1 Operating Instructions
1.1 Introduction
This instruction manual contains important information for the safe operation
of equipment supplied by Schaudt. Make sure you read and follow the safety
instructions provided.
The instruction manual should always be kept in the vehicle. All safety infor-
mation must be passed on to other users.
1.2 Operation
The WA 1208 booster increases the charging voltage available in the cara-
van to up to 14.4V, meaning the caravan battery undergoes perfect charging
when moving. It does not have any controls.
Y
For the functionality described below, it is a requirement that the 13-pin
connector plug on the towing vehicle is assigned in accordance with EN
1648-1. Also refer to the circuit diagram in Section 2.2.
It works as follows:
³
Hook up the caravan to the towing vehicle and plug the caravan connec-
tor into the vehicle.
³
Switch on the ignition and start the engine.
F
The 12 V supply voltage from the towing vehicle supplies the booster.
The green LED on the booster is ON.
F
This increases the voltage to 14.4 V. A battery connected to the boo-
ster in the caravan is charged with up to 9 A.
³
Switch off the ignition.
F
The 12 V supply voltage from the towing vehicle is isolated from the
caravan by the booster.
F
The green LED on the booster is OFF.
Y
The 13-pin connector plug on the caravan is automatically dead if it is
pulled out of the socket on the towing vehicle. This prevents the caravan
battery from discharging as a result of leakage currents.
Y
ATTENTION!
As long as the ignition on the towing vehicle is switched on, the booster is
active and the caravan battery is therefore charged. This discharges the to-
wing vehicle battery.
This is why, when the vehicle is stationary and the caravan is plugged in, the
ignition may not stay on for a long period of time without the engine running.
