EXTERNAL WIRING
A. 120 Volts AC Connection: The refrigerator is equipped
with a three prong (grounded) plug for protection against
shock hazards and should be plugged directly into a
properly grounded three prong receptacle. DO NOT cut
or remove the grounding prong from this plug.
B. 12 Volt Connection for Igniter (On Manual Models
only): The connection is made to the terminal block
marked 12 volts DC REIGNITER. The igniter must be
connected to a battery circuit and will draw about 1 amp
at 12 volts DC.
C. 12 Volt DC Connection for Heater (3-Way Models
Only): This connection is made to the terminal block
marked DC VOLT HEATER. The refrigerator must be
connected to the battery circuit with two wires of ad-
equate capacity to avoid voltage drop. The wire gauge
should be chosen with consideration to the wire length
in accordance with the Table located in the Installation
Manual appropriate for your model.
Do not use the body or chassis of the vehicle as a substitute
for either of the two conductors. No other electrical equip-
ment or lighting should be connected to the refrigerator
circuit.
D. Ignition Lock Connection (Only on Systems with a
Tag Line):
In order for the circuit board to perform certain functions,
it must receive a signal when the vehicle engine is
running. This signal wire (16 gauge minimum) should
originate at the run terminal of the ignition switch and
connect to the "IGN lock" position on the refrigerator
terminal block.
INTERNAL WIRING
Check all wires and the connectors to ensure a proper and
tight connection. Also verify the refrigerator is wired per the
wiring diagram for the model you are working on. (See
applicable wiring diagrams for your model refrigerator)
