For MES and AES it is compulsory to provide a permanent 12V DC supply at the terminals C/D (permanent voltage supply for functional electronics).

4.9.4D+ and solar connection (only for AES models)

D+ − connection:

n >Automatic Mode< the AES electronic system automatically selects the most efficient energy supply. In automatic mode the electronic system uses the D+ signal (dynamo +) of the alternator to detect 12V DC. 12V DC operation is selected only while the engine is running in

12V DC energy can be optionally achieved by mounting solar equipment to the vehicle. The solar power equipment must be provided with a solar charging controller with AES output (ade- quate charging controllers available in selected stores). The "S+ connection (Solar +) must be connected to the respective terminal of the solar charging controller (AES output). The electronic system uses the S+ signal of the solar charging controller to detect solar 12V DC.

Cable cross−sectional areas:

There are no particularly high current flows via the D+ and S+ connection; therefore no particu- larly large cross-section is required for these connections (approx. 1mm² is sufficient).
