POWER REQUIREMENTS

The Fridge/Freezer is designed to operate on AC and DC voltage inputs.
AC input
DC input
For optimum performance and effi ciency, it is important that the appliance has a reliable 15A fuse
protected DC supply in good condition. Direct connection to the battery is recommended and
reduces the risk of voltage dropping to the appliance.
It is recommended that the correct sized Automotive Electrical Cable is used for the direct connection
and that this includes a 15A fuse; do not use resettable circuit breakers. It is important that the
correct cable size is used for the installation of the DC supply as over distance the voltage can
decrease if the incorrect sized cable is being used.
DISTANCE CABLE GAUGE FOR DC INPUT
4.5m or less
4.6m and over

BATTERY MONITOR

The device is equipped with a multi-level battery
monitor that protects your vehicle battery against
excessive discharging when the Fridge/Freezer is
connected to 12/24 V supply.
If the Fridge/Freezer is operated when the vehicle
ignition is switched off, the Fridge/Freezer
switches off automatically as soon as the supply
voltage falls below a set level.
The Fridge/Freezer will switch back on once the
battery has been recharged to the cut in voltage
level.
Push, hold and release
