Electrical Wiring And Control Unit; Connecting Diagram; Connecting The Drive Motors; Connecting The Battery - Truma Mover SR Version 2 Mode D'emploi

Electrical wiring and control unit

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. 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.
Two high-power cables are factory-fitted to each motor for
the drive motor (6 mm²). Mark the relevant motor connecting
cables (motor A or B – see also connecting diagram) and tem-
porarily route them along the underbody of the caravan to the
location where it is planned to install the control unit. An exam-
ple of a suitable location for the control unit is in a bed stowage
box in close proximity to the manoeuvring 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 16).
At a distance of approx. 150 mm from the control unit connec-
tion 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.

Connecting the drive motors

The motor cables must be routed in such a way that they can-
not be torn off or damaged.
Shorten the motor cable of the drive motor furthest from the
control unit. Cut the motor cable of the closer drive motor to
the same length. The two motor cables of the drive motors
must be of the same length in order to ensure that the Mover®
can move the same distance! Excess cable must be routed in
wavy lines without loops.
Crimp the spade connector provided onto the drive motor
cable. Release the flap of the control unit connection strip by
pressing, and clamp the cable in accordance with the connec-
ting diagram (red = positive, black = negative). Please en-
sure that the connections are made properly.

Connecting the battery

Liquid electrolyte batteries must be installed in a separate box
with ventilation leading to the outside. The fuse in the positive
lead must be connected outside the box. A separate box is
not required for gel or AGM batteries. Pay attention to the bat-
tery manufacturer's installation instructions.
The outgoing lines from the terminals must be routed with a
gap between them until after the fuse in the positive lead.

Route the battery connector cables (only use the original
–
Truma cables supplied) to the control unit and attach them
securely using the clips and screws provided.
B
The battery connector cables must not be extended.
They must be routed separately from the motor cables,
and must not run over the control unit.
Route battery connector cables so that they do not chafe (par-
ticularly at leadthroughs through metal panels). Use suitable
protective leadthrough bushing to prevent damage to cables.
Connect the battery connector cables to the existing battery
terminals (red = positive, black = negative).
Incorrect polarity will destroy the electronics / control
unit.
The connection to the control unit (as per the connecting dia-
gram) must be made in the order: nut, battery connection ring
eyelet, nut (torque: 7 Nm ±1).
