INSTALLATION INSTRUCTIONS
12 V DC connection
RM2451-2551-2652-2852 : These refrigerator models are not
designed for 12 V DC operation of the cooling system. How-
ever, 12 V DC must be supplied to operate the controls.
RM2354-2454-2554-2662-2663-2862-3862 & NDR1062 :
These refrigerator models require a continuous 12 V DC sup-
ply to maintain the automatic energy system.
The connection is made to the positive (+) and negative (-)
terminals of the terminal block on back of the refrigerator, see
APPENDIX A - REARVIEW EQUIPMENT . Correct polarity must
be observed when connecting to the DC supply. Do not use the
chassis or vehicle frame as one of the conductors. Connect two
wires at the refrigerator and route to the DC supply. Ensure the
connections are clean, tight and free from corrosion.
The distance the current must travel from the battery to the
refrigerator dictates the AWG wire size to be used. Should the
wire be too small for the distance, a voltage drop will result
causing a decreased cooling capacity.

For 3-way models, the voltage drop affects the wattage output
of the 12V cartridge heater and the refrigerator performance.
The 12V DC heater is fused with a 30 amp. in-line blade fuse.
Recommended wire sizes are displayed in the following table:
REVERSING THE DOOR SWING
The refrigerator is equipped with hinges that makes it possible
to change the direction the door opens by moving the hinges to
the opposite side. A special hinge kit must be used in order to
change the door swing. For conversion kit number, refer to the
USER MANUAL (825125700), APPENDIX B - SPARE PARTS .
MOUNTING THE DOOR PANEL(S)
Optional door insert panels are available for
RM2351-2354-2451-2454-2551-2554-2652-2662-
2663-2852-2862 & NDR1062
. The refrigerator is
normally delivered without door panel(s).
Before starting the mounting work, read this instruction thor-
oughly and check that the panel dimensions are in compliance
with those given in the “Panel dimensions” table
