6.4 Connecting your fridge freezer
6.4.1 Connecting to 12/24V DC
Your ARB Fridge Freezer can be operated on either 12V or 24V DC. Your fridge freezer
is fitted with a control circuit to prevent polarity reversal and possible short-circuiting
when the unit is connected to a battery.
To connect your fridge freezer to a 12 V or 24 V DC supply:
Plug the 12/24V power lead into the DC power socket on the back panel of the
fridge freezer as shown in Figure 7.
Connect the free end of the power lead to a 12 V or 24 V DC supply.

6.4.2 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 15 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.
For cable lengths greater than 6m, ARB recommends that you consult a qualified
technician for advice on the correct cable diameter.
