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).
4.9.4 D+ 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
order to prevent battery discharge.
S+ − connection:
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).
