Connect the 120 volts AC and 12 volts DC supplies
This refrigerator operates on 120 volts (60 hertz) AC current and 12/24 volts DC current
from a battery.
CAUTION: Only connect the refrigerator directly to the battery. Because they
often generate high voltage pulses and cause transistor defects in the inverter,
no other switches, lead wires, or electrical equipment should share the wiring
between the refrigerator and battery. Do not use an extension cord.
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 ltered DC power (See Art01521).
As the distance from the vehicle battery to the refrigerator increases, the correct AWG
wire size also increases. If he wire size is too small for the distance, a voltage drop oc-
curs. 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 16 AWG wire and a 10 Amp fuse.
- If the distance is between 12 and 20 feet, use 14 AWG wire and a 10 Amp fuse.
- If the distance is more than 20 feet, use 12 AWG wire and a 10 Amp fuse.
