tions and a relay for the power supply (controlled using the ignition) (see

Z At 12 V battery in the caravan:

If the LED display of the ATC lights up or flashes although the caravan is con-

nected to 240 V and not to the towing vehicle, proceed as follows:

 Switch the 240 V safety cut-out (see Fig. 93) and the main switch battery (see

Fig. 86) on and off briefly in order to interrupt the current flow.

 If no panel with main switch battery exists, interrupt the current supply directly

at the 12 V battery.
