D+ connection and Solar Control connection
( AES only )
D+ connection:
The D+ control connection must be connected to the respective vehicle
terminal (alternator signal while motor is running).
Solar control input (S+):
Connection only when using a solar system with a solar charging control-
ler with AES output.
The respective solar charging controllers are available from a specialized dealer.
The “Solar” (S+) control connection must be connected to the respective
terminal of the solar charging controller (AES output).
Cable cross-sections
There are no particularly high current flows via the D+ and S+ connection;
therefore no particularly large cross-section is required for these connections
(approx. 1mm²).
