Set the correct distance between tyres and rollers (20 mm) with
the spacer gauge provided by moving the drive assemblies (in
the disengaged position) in the longitudinal direction. The mov-
able connection pipe makes it possible to adjust to the frame
width.

Move the drive assemblies in a lateral direction in such a way
that as much of the tread area of the tyre / drive roller as poss-
ible is covered.
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 be
resting on the wheels when doing this.
Place the movable connection pipes in the centre (use the mark-
ing) and fix each one with a threaded bolt (g) M8 x 12 (
15 Nm
).
The threaded bolts are coated with sealant, and must
therefore only be bolted in once.
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.

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. 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 con-
necting cables (drive assembly A or B – see also connecting di-
agram) 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 manoeuvring sys-
tem,
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
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.
