Assemble the parts of the cross actuation bar (4 & 5) and connect them to the motor units (1 & 2) with the
nylon nut and bolt (factory fitted) onto the cross actuation bar-connectors (Fig. 2 & Fig. 2A). Nuts must be no
more than finger-tight at this stage.
Make sure that the main cross bar (12) and the cross actuation centre bar (4) are positioned in the middle of
the caravan (the centre of the bar is marked).
With the main assembly is loosely fitted onto the chassis, slide the whole assembly along the chassis until the
rollers are 20mm away from the surface of the centre each tyre (Fig. 12). Two 20mm spacers (30) are provided.
It is vitally important that each roller is at exactly the same distance away from the tyre.
The whole assembly must be parallel to the caravan/trailer axle.
Slide the motor units in or out of the cross bar (3) accordingly to ensure the 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 cover (Fig. 13)
is not too close to the surface of the tyre/shock absorber. The minimum clearance when
the drive units swivelled in is 10mm.
Fully tighten the four bolts (Fig. 2B) on the main cross bar (3) and the four bolts (Fig. 2C) on cross
actuation assembly (4 & 5).
Fully tighten all the nylon nuts on both clamping assemblies (Fig. 8). First tighten the diagonal placed M10x60
bolts with a 20Nm torque, and then M10x50 bolts to a 40Nm torque.
Re-check the distance of 20mm from the rollers to the tires, the position of the aluminium rollers in addition to
the surface of the tire and finally the distance between the plastic gear cover (Fig. 13) and the tires & shock
absorbers (>10mm). The weight of the caravan musty be on the wheels when doing this. If necessary, loosen
the bolts and re-adjust the position of the assembly.
Re-check that all bolts/nuts have been tightened to the correct torque!
The main mechanical components have now been installed.
INSTALLATION - ELECTRICAL/ELECTRONIC COMPONENTS
Make sure the 12V supply from the battery and any 230V electricity supply are disconnected.
Remove battery cable terminals and disconnect any external electrical power before starting work.
Find a suitable place for the electronic control unit (32), such as a storage area, under a seat or a bed. Make
sure this place is dry and close to the battery (40cm to 60cm). The electronic control unit can be mounted
vertically on a side wall or be mounted flat. When mounted vertically, the connections must point downwards to
avoid any short-circuits by objects falling into it.
Fix the electronic control unit securely into position with two screws M5x40 (35). Note: if the provided screws
are not of suitable length or type for the desired location/material please substitute these as appropriate.
Drill a 25mm hole through the floor of the caravan approximately 150mm centrally in front of the control unit
(32) terminals.
Caution! Take extra care to avoid any chassis members, gas pipes and electrical wires!
Route and connect the motor-cables in accordance with wiring diagram (Fig. 15) (red = positive, black =
negative).
The wiring diagram (Fig. 15 + 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.
Table . A
FRONT OF AXLE FITTING
Motor A Positive (+) cable to terminal 4
Motor A Negative (-) cable to terminal 3
Motor B Positive (+) cable to terminal 2
Motor B Negative (-) cable to terminal 1
Mark 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.
Table . B
REAR OF AXLE FITTING
Motor A Positive (+) cable to terminal 1
Motor A Negative (-) cable to terminal 2
Motor B Positive (+) cable to terminal 3
Motor B Negative (-) cable to terminal 4
