• For a motor home the house battery and the
vehicle battery may be the same battery.
• For a caravan the 12 volt connections can only
be made to separate batteries.
12V AND “D+” CONNECTION
The refrigerator is equipped with two terminals intended
for connection to 12 volt.
RM4605 and RM4805:
One terminal is marked “
12V DC
HOUSE
” and the other
“12V DC VEHICLE”
, see Fig. 14.
D + D +
D+ signal from either a
12V or a 24V DC alternator.
Only 12V DC to the PC board.
Under no circumstances can
24V DC be connected to the
PC board.

Before leaving, the installer should:
•
Check all connections for gas leaks with soap and water.
DO NOT
use an open flame for detecting leaks!
•
Ignite the burner to ensure correct operation of gas
valve, burner and ignition.
•
Instruct the user on the correct method of operation.
In case the appliance fails to operate correctly after all
checks have been carried out, contact the authorized
service provider in your area.
ELECTRICAL CONNECTION
The electrical installation must be carried out by autho-
rized personnel.
For mains voltage operation, it is important
that the circuit to and in the motor home / car
-
avan is effectively earthed.
The refrigerator is equipped with a three-prong (ground-
ing) plug for your protection against shock hazards and
should be plugged directly into a properly grounded three
prong receptacle.
DO NOT
cut off or remove the ground-
ing prong from this plug!
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified per
-
sons in order to avoid a hazard.
230-240V SUPPLIES
Check that the voltage stated on the data plate is the
same as the main voltage in use (230-240V).
Electrical leads must be routed and secured
so that they cannot come into contact with hot
or sharp parts of the refrigerator.
The free length of the cord is
1 m. It is recommended that
the receptacle is located on
the left side of the refrigerator
(viewed from the rear) and ap-
proximately 150 mm from the
floor. This allows easy access
through the vent door.
The cord should be routed to
avoid direct contact with the
burner cover, flue cover or any
other components that could
damage the cord insulation.

CONNECTION MARKED “12V DC VEHICLE” (RM4605/
RM4805)
This connection supplies the 12V DC heating element.
The (+12V) and (-12V) poles have to be connected di-
rectly to the vehicle battery. Via a suitable connection to
the tow vehicle when fitted to a caravan.
The (+12V) supply wire, connected to the terminal block
(S) on the wiring diagrams, has to be fused according to
the table below. Do not use the chassis for the return lead.

Cross-sections
The wires connected to this terminal must have the fol-
lowing minimum cross section area:
•
RM4605/RM4805
Maximum length of 8 meters from refrigerator to the
battery. 10 mm

cross-section low voltage multi strand
cable.
Cable lengths > 8 meters will require a larger cross-sec-
tional cable.
CONNECTION MARKED “CONNECT TO PERMANENT 12
VOLT “12V DC HOUSE”
(RM4605/RM4805)
This connection supplies the AES refrigerator control sys-
tem and must not be interrupted at any time while using
the refrigerator on 240 volt, gas, and 12 volt. This is a
permanent 12 volt connection.
The (+12V) and (-12V) poles have to be connected di-
rectly to the permanent 12V DC house battery. Do not use
the chassis for the return lead.
The 12V supply must not be connected to a voltage con-
troller or similar device as the AES control system itself
monitors the DC voltage.
The +12V must be permanently attached and must not be
cut out when the ignition key is turned off. All connections
should be screwed or soldered to keep voltage drop to a
minimum.
