IMPORTANT in the case of installation of equipment that needs permanent exclusion of the battery parallel
relay (ref. 1), you must remove the R resistor (ref. 2). The resistor can be removed using a wire cutter,
being careful not to damage the PCB traces below.

ELECTRICAL SYSTEM FUNCTIONS
b) by 230V net: buffer system through battery
c) by solar panel: through solar regulator.
An electronic device controlled by the “+ key” ON
switches on the D+ functions (batteries parallel, OUT
D+ simulated output, awning light etc.) when the car
battery voltage is > 13.5V and switches them off with
the “+ key” OFF or with voltage < 12.5V.
D+ FUNCTIONS
The D+ functions can be activated only if the B2
leisure battery is connected.
charger.
a) by alternator: through the separating relais,
s when the engine i started.
Operation without SMART ALTERNATOR:
CAR BATTERY (B1) RECHARGING
When the battery charger is charging, an electronic
device allows a recharging ( A) of
the car battery (B1), the system gives priority to the
leisure battery (B2).
nominal current 2
LEISURE BATTERY (B2) RECHARGING
Condition A: with “+ key” ON signal and car battery
voltage > 13,5V. The functions are
deactivated with “+ key” OFF or with
voltage < 12,5V.
Condition B: with “+ key” ON signal and “D+”
negative signal (-). The functions are
deactivated in absence of one of
those two signals.
Operation with SMART ALTERNATOR (present on
all DS distribution boxes manufactured since
September 2019)

:
The D+ functions can be activated only if the B2
leisure battery is connected.
For vehicles equipped with SMART ALTERNATOR
n electronic device switches on the D+ functions
(batteries parallel, OUT D+ simulated output, awning
light etc.) when the engine is running. The D+
functions are activated in presence of at least one of
following conditions:

N.B.: In presence of both conditions, the functions
are deactivated in absence of the “+ key” signal.
