■ Electric Power Sources
Connect only to either of the following power sources:
• 240V AC from wall outlet (U1D type is AC120V)
• 12V or 24V DC battery.
＊ This plug is for DC12V only (Fig 2). DC24V is the other cord (option).

DC BATTERY OPERATION (POLARITY GUARD)
If reverse polarity does occur, the special thermal fuse will blow and become inoperable.
＊
＊
Pay due attention to the correct polarity, the inner contact of cigarette lighter socket adapter must be
connected to the positive supply, while the outer (negative) contact is connected to earth.
(Most modern vehicles are wired on the negative earth system, but there may still be older vehicles and
imported ones with the positive to earth connections).

AC and DC voltages may be connected simultaneously, when AC will be automatically selected if both
voltages are applied.
2. INSTALLING A REFRIGERATOR
If the voltage is too high it will damage the product. If it’s too low, the cooling efficiency will be reduced,
the running time will increase and the battery will be subjected to an increased load.
In order to protect the power supply from damage caused by reversed polarity, the product is fitted with
an automatic polarity guard. Should incorrect polarity be applied, the green power lamp will not light up and
the product will not operate.
The serviceability of the special thermal fuse can only be checked by testing it's continuity with a
multimeter.
Following the correction of the current supply, the green power lamp will light up and normal operation will
resume.
When not using the product, remove the cigarette lighter plug of the cord from the cigarette lighter socket
of the vehicle to prevent unnecessary drainage of the car battery.
