Make sure the 12V supply from the battery and any 230V electricity supply are disconnected.
Find a suitable place for the Electronic Control Unit (1), such as a storage area, under a seat or a bed. Make sure this place is dry and
close to the battery (30m to 60cm). The unit can be mounted on the bottom (horizontal) or on the wall (vertical). When choosing
location, ensure that the unit cannot easily be damaged.
Fix the Electronic Control Unit(s) securely into position with four screws (19). Note: if the provided screws are not of suitable length
or type for the desired location/material please substitute these as appropriate. For an AWD installation connect the link cable
between control box ports E (Fig.3).
Drill a 25mm hole through the floor of the caravan approximately 150mm centrally in the front of the control unit (1) terminals.
Caution! Take extra care to avoid any chassis members, gas pipes and electrical wires!
To wire motors locate the terminals on motor portions - these can be identified from the Installation Manual. Please also refer to
Fig.4 - attach positive wire (red) to terminal marked in red on each mover (Fig.4 - 3 & 1). Attach negative wire (black) to remaining
terminal on each motor (Fig.4 - 4 & 2).
Route the motor-cables in accordance with wiring diagram (Fig.4) (red = positive, black = negative).
Keep all motor cables an equal length, so it is advised that each pair of cables is routed towards the centre
line of the caravan’s length and then onward to the drilled hole near the Control Unit (1). On a 2 motor
system, on heavier caravans you may need to upgrade to our thicker gauge wiring to maintain maximum
performance on steep inclines.
The wiring diagram (Fig.4 + Table.A (see below) depicts the wiring route when installing the motor units in
FRONT
of the wheels/
axle
towards the ‘A’ frame. Please refer to Table.B (below) for fitment of the motor units to the
REAR
of the axle. Note: If you are
fitting two sets of motors onto a twin-axle caravan to form a AWD Quattro system refer to the wiring diagrams on pages 9 & 10 of
this manual to ensure rear axle is correctly wired.
Mark the ends of the Motor Cables (12 & 13) for both motor units using the cable markers (25). The cables for the left and the right
motor should have the same length. Avoid any loops.
Route the motor cables along the underside of the caravan floor, inside the supplied Cable Trunking (11) (this will protect the
electrical cables against sharp edges and dirt) through the drilled hole. Also use a combination of the smaller P-clips (21) where
appropriate.
Secure the Cable Trunking (11) to the chassis or under body of the caravan by using the P-clips (20) and screws (19). Once the motor
cables are through the drilled hole next to the Control Unit (1), cut the cables, ensuring that they are the same length. Remove
approx. 5mm of the insulation for the ends. Fix the spade connectors (24) by using crimping pliers. A secure and good quality
connection on each cable is essential.
Attach the connectors to the terminals on the Control Unit (1) (see wiring diagram Fig.20).
Route the Battery Cables (14 & 15) from the battery to the Control Unit (1).
It is recommened to install an in-line fuse between the positive battery cable and the control unit as well as utilising heavier gauge
cabling between the battery, isolation switch and control unit when installing a four motor system. Please consult your dealer for
further details if necessary.
The Power Isolation Switch (29) will also need to be installed in-line between the Control Unit and the battery, so please plan where
this will be located. If available. This switch must not be installed in the same sealed area as the battery, but may be installed in an
adjacent seperately sealed area, usually there is a space to the side of the battery near the mains power connection.
