Connect The 12 Volt Dc Supply - Norcold DCL4 Série Manuel D'utilisation Et D'installation

Connect the 12 Volt DC Supply

This refrigerator operates on 12/24 volts DC current from a battery.
Only connect the refrigerator directly to the battery. Because they often generate high voltage pulses and cause
NOTICE
transistor defects in the inverter, no other switches, lead wires, or electrical equipment should share the wiring between
the refrigerator and battery.
When using either a converter or a battery charger,
make sure that they are connected in parallel
between the battery and the refrigerator. Do not
use a converter or battery charger to supply the
DC power directly to the refrigerator because these
two devices do not supply filtered DC power (See
Art01521).

As the distance from the vehicle battery to the
refrigerator increases, the correct AWG wire size
also increases. If the wire size is too small for
the distance, a voltage drop occurs. The voltage
drop decreases the cooling performance of the
refrigerator.
1. Norcold recommends that you use the following
wire and fuse sizes:
- Measure the distance from the vehicle battery to the refrigerator:
- If the distance is less than 12 feet, use 12 AWG wire and a 15 Amp fuse.
- If the distance is between 12 and 20 feet, use 10 AWG wire and a 15 Amp fuse.
- If the distance is more than 20 feet, use 8 AWG wire and a 15 Amp fuse.
- Twist the lead wires to reduce the radio interference
and induction of a high voltage surge from the outside
(See Art01518).

This wiring is already in the vehicle. It is
located behind the wall trim panel.
2. Push the DC connector of the refrigerator completely
into the DC plug of the vehicle.
