Installation and Owner’s Manual 11This 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 causetransistor defects in the inverter, no other switches, lead wires, or electrical equipment should share the wiring betweenthe refrigerator and battery.When using either a converter or a battery charger,make sure that they are connected in parallelbetween the battery and the refrigerator. Do notuse a converter or battery charger to supply theDC power directly to the refrigerator because thesetwo devices do not supply filtered DC power (SeeArt01521).Correct ................................................................ 1Incorrect .............................................................. 2Refrigerator ......................................................... 3Battery charger or AC/DC converter, etc............. 4Transistorized DC power supply ......................... 5Condenser .......................................................... 6Battery................................................................. 7As the distance from the vehicle battery to therefrigerator increases, the correct AWG wire sizealso increases. If the wire size is too small forthe distance, a voltage drop occurs. The voltagedrop decreases the cooling performance of therefrigerator.1. Norcold recommends that you use the followingwire 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 interferenceand induction of a high voltage surge from the outside(See Art01518).Correct ....................................................................1Incorrect ..................................................................2Refrigerator .............................................................3Battery.....................................................................4Electrical equipment................................................5Twisted lead wires...................................................6This wiring is already in the vehicle.
