4.9.4 D+ and solar connection (only
for AES models)
D+ signal connection
In >Automatic Mode< the AES electronic
system automatically selects the most efficient
energy supply. In automatic mode the electro-
nic system uses the D+ signal (dynamo +) of
the alternator to detect 12V DC. 12V DC ope-
ration is selected only while the engine is run-
ning in order to prevent battery discharge.
S+ signal 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
(adequate 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 parti-
cularly large cross-section is required for these
connections (approx. 1mm² is sufficient).
