Electrical Wiring And Control Unit; Connecting Diagram - Truma Mover XT4 Einbauanweisung

Electrical wiring and control unit

The Mover XT4 is only suitable for connection to 12 V batter-
ies (DC voltage).
Before commencing work, disconnect the battery and
any external electrical power supplies.
The electrical installation must comply with the technical
and administrative regulations of the respective country of
use (e.g. EN 1648-1). National regulations and rules must be
followed.
Connector cables for the drive motor and data cables are pre-
installed on each drive assembly. Mark the relevant motor con-
necting cables (drive assembly A or B – see also connecting
diagram) and temporarily route them along the underbody of
the caravan to the location where it is planned to install the
control unit. An example of a suitable location for the control
unit is in a bed stowage box in close proximity to the manoeu-
vring system, at least 40 cm away from the battery. The
control unit must not be in a metal housing.
Place the control unit in the stowage box and secure with the
chipboard screws provided (5 x 25).
At a distance of approx. 150 mm from the control unit con-
nection strip, mark a hole with a diameter of 25 mm on the
floor of the caravan through which to pass the wiring looms.
Before drilling, check for underlying frame sections, gas
lines and electrical cables.
Drill the hole and pass the cables through the floor of the
caravan to the control unit, routing them in such a way that
they cannot chafe (especially where they pass through metal
panels). Use the protection pipes provided to prevent damage
to cables.
The drive motors move when operating. In order to
compensate for this, secure the cables in this area
loosely with a little play to prevent the cables from being
stretched. No cable must be laid over the control unit.
Secure the cables to the chassis or underbody using the clips
and screws provided.
Seal the hole in the vehicle floor with plastic body sealant.
