assembly must be parallel to the caravan/trailer axle.
Loosen the locking bolts (Fig.1B) to enable you to slide the motor units in or out of the centre cross bar (5) accordingly
to ensure each roller will have the maximum possible contact with the tread of the tyre. Ensure that the position of each
motor unit does not obstruct shock absorbers (if fitted) and that the gear housing (Fig.2F) has a minimum distance of
10mm to the inner surface of the tyre when the mover is engaged (Fig.8).
Fully tighten the four nylock nuts (13) on both clamping assemblies (Fig.9) to a torque setting of 40 ft lbs/55Nm, then the
four bolts (Fig.1B) on the Cross Bars (3&4) to a torque setting of 9ft lbs/12Nm. Re-check the distance of 20 mm from the
rollers to the tyres and if necessary, loosen the bolts and re-adjust the position of the assembly.
If fitted the bolts that secure each motor unit should be tightened to a torque setting of 27ft lbs/37Nm.
Once satisfied with the position of the assembly, fit and tighten the Chassis Stop Nuts & Bolts (16) , one pair in each of
the Upper Chassis Clamp Plates (see Fig.9). Tighten to a torque setting of 40 ft lbs/55Nm. The Stop Bolts grip the lip
of the chassis and help prevent the mover from sliding along the chassis. The main mechanical components have now
been installed.
Optional Cross Actuation Bar
Assemble the parts of the cross actuation bar (24 & 25) and connect them to the motor units (1 & 2) with the nylock nut
and bolt (factory fitted) onto the cross actuation bar-connectors (see Fig.1A). Tighten the four bolts (Fig.1C) on the Cross
Actuation assembly (24 & 25) to a torque setting of 9ft lbs/12Nm

All the electrical components are pre-wired with weatherproof two-pole plug connectors.
Each motor unit has a plug connector secured to the top which are pre-wired to the positive (+) and negative (-)
terminals of the motors.
The supplied carry case (6) contains the electronic control unit (7) which is also pre-wired. The cable that attaches to
both motors is spooled around the cable storage hooks on the lid of the case. The motor cable is a four-core cable that
splits into two connectors, one for each motor.
The battery cable is also pre-wired to the Control Unit (7) and is stored in the same manner as the motor cable.
The motor connections are pre-configured for installation of the motors in FRONT of the wheels/axle (see Table A).
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 full Quattro® system then both Table A & Table B wiring will be utilised. Please
refer to Fig.21.
A motor cable extension (21) is supplied so that both motors can be plugged in on one side of the caravan/trailer. When
installing the cross bar it needs to be determined which side is most convenient for you to plug into the motors. In
normal circumstances, during operation, the carry case containing the electronics and cables would be located in the
doorway of your caravan or in an externally accessible locker. The motor cable extension should be connected to the
plug on top of the motor on the opposite side to where you want to be able to access both motor plugs and should be
cable-tied to the cross bar assembly. That means that when you connect both motors to the Control Unit it can be done
from just one side for convenience.
Please refer to the wiring schematic to determine the correct configuration as the plug connectors for motor A and B
are colour coded. The wiring schematic (Fig.16) shows the configuration for front of axle fitting with the Extension Cable
(21) connected to locate both motor plug connectors on the left hand side of the caravan. If you require the motor plug
connectors to be located on the right hand side then you must swap the connections of the spade connectors on the
Control Unit (7) in accordance with Table.B.
