POWER REQUIREMENTS
The fridge/freezer is designed to operate on AC or
DC voltage.
AC input 240V AC at 50Hz (e.g. electrical
power point)
DC input 12V or 24V DC (e.g. car cigarette lighter
or car battery)
The power supply automatically switches the
fridge/freezer to mains operation when
connected to 240V mains power, even if
the 12V/24V DC power cable is connected.
If the fridge/freeze is operating when the vehicle
ignition is switched OFF, the fridge/freezer will
switch OFF automatically when the power
source voltage falls below the Battery Monitor
cut-out setting.
The fridge/freezer will automatically switch
back ON when the vehicle is re-started and
the power source voltage reaches the Battery
Monitor cut-in setting.
OPERATING YOUR FRIDGE/FREEZER WITH
12/24V DC
Plug the 12V/24V DC power cable into the DC
power socket (as circled) on the end of the
fridge/freezer and then connect to the vehicle
cigarette lighter socket or suitable 12V or 24V
DC power source.
The fridge/freezer will automatically turn on, there
is no requirement to switch the appliance on.
The display will automatically show the current
internal cabinet temperature.
For optimum performance and efficiency, it is
important that the fridge/freezer has a reliable
DC power source available. Direct connection to
the battery is recommended and reduces the
risk of voltage dropping to the appliance.
Use only the 1.5m DC power cable supplied with
the fridge/freezer.
Important: If a DC extension cable is required
we recommended use of a 6mm dia. (AWG11)
4.58mm
2
Twin Sheath Two Core cable with direct
connection to the positive and negative battery
terminals with 15A inline fuse protection.
The fridge/freezer is equipped with an electronic
control system that will prevent polarity reversal.
In the event that the battery connection is
reversed the unit will not start or operate. The
power input socket is fitted with a 15A blade
fuse for protection.
12/24V DC POWER REQUIREMENTS
If your fridge/freezer is cutting out prematurely, it
could be due to:
1. The low voltage protection being set too high on
the Battery Monitor
2.
DC power cable and/or connections are not
suitable to carry the required current. Check the
power cable and all connections and adjust the
Battery Monitor on the control panel.
The fridge/freezer is equipped with a multi-level
Battery Monitor that protects your vehicle battery
against excessive discharging when the fridge/
freezer is connected to 12V or 24V DC power
source.
Important: When using the fridge/freezer with DC
power supply, we recommended setting the Battery
Monitor to LOW (L).
Note:
A battery charger may only be connected
to the battery when the fridge/freezer has been
disconnected from the DC power source.
Over-voltage may cause damage to the electronics
of the fridge/freezer.
Your fridge/freezer is equipped with reverse
polarity protection. It protects your fridge/
freezer against reverse battery connection
and short circuit.
