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)
WRONG
3) To prevent radio noise and avoid absorbing high surge
frequency, insert a capacitor of 10000μ-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.
