Connection Plan for Operation with 13-pole Trailer Connector
for Caravan and Living Compartment Operation:
Always install the unit
as close as possible
to the
BOARD battery
.
The configuration of the connector contacts of the trailer might be deviating and must be checked for each
individual case. The drawn configuration of the connector contacts provides the following advantages:
The power for the charging converter is supplied at connector No. 9 (+) and 13 (-), and is switched on or
switched-off by the switched 12 V signal No. 10.
During extended standstill periods and charging of the BOARD battery (mains, solar), the recharging
branch of the VCC 1212-20 C (12 V/0…1 A) can be used for trickle charging of the vehicle's STARTER
battery.
The 12 V heating cartridge of the refrigerator can be connected to the connector No. 10 (+) and 11 (-)
during driving, while the supply of the refrigerator control is taken over by the BOARD battery.
Reverse battery (12 V +/-
mix-up) at the large power terminals IN 12 V and OUT 12 V
must be avoided
in any case
. This will result in serious damage of the unit!
Observe the cross-sections and lengths of the cables.
Insert fuses near the battery for protection of the cables.
