Fitting The Cross Actuation Device; Electrical Wiring And Control Unit - Truma Mover SX Mode D'emploi / Instructions De Montage

Move the drive units in a lateral direction in such a way that
as much of the tread area of the tyre as possible is covered.
Ensure that there is an adequate distance between the gear-
box and the tyres / shock absorbers so that they do not come
into contact.
The minimum distance with the drive rollers engaged is
10 mm.
Figure 27
Once the drive units have been correctly positioned, tighten
the bolts (c) of the fastening kit a little, then check the re-
quired distances again. The weight of the caravan must be
resting on the wheels when doing this.
Place the movable connection pipe in the centre (use the
marking) and fix each side with 1 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 fastening
kit (M10) several times in turn with a torque of 25 Nm.

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

Fitting the cross actuation device

Make sure that the drive rollers are not engaged on the tyres
(on both sides).
Push the connection pipes (1) into the central pipe (2) with the
holes facing outwards.
Push the connection pipes (1) onto the toggle crank (a). Insert
the bolts (5) through the toggle crank and tighten with the
nuts (4) (10 Nm ± 1 Nm).
Centre the central pipe (2), measuring again if necessary. In
this position, tighten the 2 threaded bolts (3) (15 Nm). Finally,
check all the bolted connections again.

Engage the rollers using the lever provided. The drive rollers
should now be engaged on both sides. Check the opposite
side as well. Disengage the drive rollers again.
Repeat this procedure on the opposite side.

Electrical wiring and control unit

Installation and connections must be done by trained
specialists!
The Mover is only suitable for connection to 12 V batteries
(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.
Two high-power cables are factory-fitted to each drive unit for
the drive motor (6 mm²). Mark the relevant motor connect-
ing cables (motor A or B – see also connecting diagram) and
temporarily route them along the caravan floor 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 assistant at least 40 cm
away from the battery, and it must not have a metallic
housing.
Place the control unit in the stowage box and secure with the
chipboard screws provided (5 x 16).
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,
tanks, gas lines, water pipes 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 during engagement and
disengagement. In order to compensate for this, se-
cure the cables in this area loosely with a little play to pre-
vent 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 caravan floor with plastic body sealant.
