The center terminal of the plug must be connected to the
positive line while the side contacts to the negative or earth.
If reversely connected, the fuse in the plug will blow and the
6.2.2 Onboad direct wiring with optional kit
3) To prevent radio noise and avoid absorbing high surge
frequency, insert a capacitor of 10000
μ
-F as shown in (Fig.3)
below.
4) Selecting the correct gauge for wiring is important to avoid
voltage drop. Follow the chart below when wiring the
refrigerator to the battery.
1) Twisting lead wire
To further reduce the radio interference during DC operation,
twist the negative and positive cables (use separate cables)
together into a spiral form, between the battery and the DC
outlet socket.
2) Connecting refrigerator directly to battery
Any switches and lead wires for other electrical equipment
should not be shared with the wiring between the refrigerator
and the battery. Other equipment can generate high voltage
pulses which may cause transistor damage to the refrigerator
power supply. (See Fig.2)
refrigerator will become inoperable until the fuse is replaced.
