General Connection Plan for Operation without Connector,
such as in smaller campers or boats:
Always install the unit
as close as possible
to the
BOARD battery
.
Connection "D+":
With "D+": Control input for charging converter ON / OFF (preferential).
Without "D+": Charging converter operates voltage-controlled (also refer to
Function Selection, page 5, 2).
During extended standstill periods and charging of the BOARD battery, the recharging branch of the VCC
1212-20 C (12 V/0…1 A) is used for trickle charging of the vehicle's STARTER 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.
