RH 2 Manoeuvring Assistant
Connecting the battery
Incorrect battery connection results in a control unit fault.
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 battery
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 ca-
bles supplied) to the control unit and attach them securely us-
ing the clips and screws provided.
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 lead-throughs through metal panels). Use suitable
protective lead-through bushing to prevent damage to cables.
Connect battery connector cables to the existing battery termi-
nals
(red = positive, black = negative).
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).
Connect fuse in the positive lead (150 A) near the positive
terminal.
Function check
Check whether the battery is fully charged for operating the
manoeuvring assistant.
Position the caravan on open, level ground and apply the park-
ing brake, or secure with chocks to prevent it from rolling away.
The drive rollers must not be in contact with the wheels and the
corner jacks must be raised.
Connect the battery terminals to the battery. Check that all ca-
bles are securely attached and not hot, and that there are no
signs of short circuits etc.
Move the slide switch on the remote control to the “On” po-
sition. This switches on the remote control, and green LED
flashes until the control unit is ready for operation. If the LED
does not light up, check the polarity and condition of batteries
in the remote control. The remote control switches itself off af-
ter about 60 seconds if no controls were actuated.
Check that neither drive motor is running. With the remote
control switched on at a distance of no more than 2 m from the
control unit, push the slide control forwards. Both drive rollers
should now rotate forwards.
Move the slide switch on the remote control to the “Off” posi-
tion
to switch off the remote control and therefore the ma-
noeuvring assistant.
Engage the drive rollers using the lever provided. Turn the
engagement lever until it locks into position both mechanically
and noticeably and can no longer be turned without excessive
force (the end position is roughly horizontal).
Ensure that there are no obstacles around the caravan, release
the parking brake and remove the chocks and switch on the re-
mote control. Now check all functions several times in accord-
ance with the operating instructions.
Apply the caravan’s parking brake and secure with chocks
to prevent it from rolling away. Move the slide switch on the
remote control to the “Off” position
to switch off the remote
control and the the manoeuvring assistant. Disengage the drive
rollers using the lever and check the distance between the roll-
ers and tyres again. Readjust if necessary.
The distance between the disengaged drive rollers
and tyres is 20 mm.
Warnings
The installer or vehicle owner must apply the yellow sticker
with the warning information, which is enclosed with the ap-
pliance, in a location in the vehicle where it is clearly visible to
all users (e.g. the wardrobe door). Any missing stickers can be
requested from your dealer.
