Electrical Connections -
12 Volt DC
All Norcold refrigerator models require
a 12 volt DC supply (See Figure 5.1). 12
Volts DC is required to operate the
Mode Selector (Eyebrow board) and
temperature control circuits and maintain
the automatic Ignition gas mode. The
DC lead connections (1/4" male quick
connects) are at terminals located on the
Power Supply at the rear of the refrigera-
tor. One terminal is marked positive (+)
and the other negative (-). Correct polar-
ity must be observed when connecting
to the DC supply. Do not use the chassis
or vehicle frame as one of the conduc-
tors. Connect two wires between the re-
frigerator and the DC supply.
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. In the case of 3 - way models,
the voltage drop affects the wattage
output of the cartridge heater and re-
sultant refrigerator performance. See
the adjacent wire and fuse chart for
the correct wire and fuse size.
Electrical Connections -
120 Volt AC
All Norcold refrigerators are equipped
with a three prong plug for protection
against shock hazard (See Figure 5.2).
They must be connected into a recog-
nized three prong attachment recepta-
cle. The cord must be routed so as not
to come in contact with the Burner cover,
flue pipe, or any other component that
could damage the cord insulation.
DO NOT REMOVE (CUT) GROUND-
ING PRONG FROM THE REFRIG-
ERATOR AC POWER CORD. RE-
MOVAL OF THIS PRONG CAN RE-
SULT IN A SEVERE ELECTRICAL
SHOCK, AS WELL AS, VOIDING THE
REFRIGERATOR ELECTRICAL CER-
TIFICATION AND WARRANTY. EX-
