Electrical Wiring And Control Unit; Connecting The Drive Motors - Truma GO2 RH1 Gebrauchsanweisung, Einbauanweisung

Electrical wiring and control unit

The Manoeuvring Assistant 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 cara-
van to the control unit, routing them in such a way that they
cannot chafe (especially where they pass through metal pan-
els). 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.

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 the same length to ensure that the Manoeuvring
Assistant 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 flap of control unit connection strip by pressing, and
clamp cable in accordance with connecting diagram (red =
positive, black = negative). Please ensure that the connec-
tions are made properly!
