12/24 V DC wiring requirements
To ensure optimum performance of your ARB Fridge Freezer, it is important that your
wiring system is capable of carrying the required load. The accessories wiring system in
many vehicles is not adequate for such a task.
ARB recommends that a dedicated wiring circuit be installed to power the fridge
freezer. This circuit should be as short as possible and be connected directly to the
power supply via a 10 Amp fuse.
For an automotive or marine installation, ARB recommends that the wiring circuit be
connected to an isolated power supply like an auxiliary battery system. This will prevent
discharge of the main starting battery.
For cable lengths up to 6m, ARB recommends a minimum cable diameter of 6 mm
automotive cable (4.6mm
2
).
For cable lengths greater than 6m, ARB recommends that you consult a qualified
technician for advice on the correct cable diameter.

Connecting to an engine driven generator
Please take note of the following points before connecting your ARB Fridge Freezer to
an engine driven generator.
The generator must be fitted with an automatic voltage regulator. It must supply
a standard, pure sine wave AC voltage, without fluctuation in voltage or
frequency (eg 120 VAC~60Hz or 240 VAC~50Hz).
When using the DC output from your generator, a battery of correct voltage (12
or 24V) must be connected between the generator and the fridge freezer.
The fridge freezer should be turned off when starting and stopping your
generator.
CAUTION – Some engine driven generators are not suitable for powering your fridge
freezer.
