Electrical Wiring And Control Unit; Connecting Diagram - Truma Mover XT Mode D'emploi / Instructions De Montage

Once the drive assemblies have been correctly positioned,
tighten the bolts (c) of the mounting set a little, then check the
required distances again. The weight of the caravan must rest
on the wheels when doing this.
Place the adjustable centre bar in the middle (mark the posi-
tion before assembly if necessary), tighten the 2 bolts (20 Nm)
and lock using the lock nuts.
Re-check the distance of 20 mm from the tyre (with the
wheels under load). Then tighten the 2 bolts of the mounting
set (M10) alternately to 25 Nm.

The bolts are coated with sealant, and must therefore
only be bolted in once.

Electrical wiring and control unit

The Mover® XT / XT2 is only suitable for connection to 12 V
batteries (DC voltage).
Before commencing work, disconnect the battery and
any external electrical power supplies. If unsure about
the electrical connection, have the work performed by a quali-
fied vehicle electrician.
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
connecting cables (drive assembly A or B – see also connect-
ing 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.
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 cara-
van 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 cable to the chassis or underbody using the clips
and screws provided.
Seal the hole in the vehicle floor with plastic body sealant.
