Connecting the cooler
Connecting to a battery (Vehicle or boat)
The cooler can be operated with 12 V or 24 V DC.
Caution – Danger of damaging the device!
Disconnect the cooler and other consumer units from the battery before
you connect the battery to a quick charging device.
Overvoltage can damage the electronics of the device.
For safety reasons the cooler is equipped with an electronic system to
prevent polarity reversal. This protects the cooler against short-circuiting
when connecting to a battery.
Plug the 12/24-V connection cable (Fig
1
2, page 1) into the DC
voltage socket, the cigarette lighter or a 12 V or 24 V socket.
Connecting to a 100–240 V AC mains (E.g. in the home or office)
Caution – Danger of electrocution!
Never handle plugs and switches with wet hands or if you are standing
on a wet surface.
Caution – Danger of electrocution!
If you are operating your cooler on board a boat from a mains
connection of 100–240 V AC, you must install a residual current circuit
breaker between the 100–240 V AC mains and the cooler.
Seek advice from a trained technician.
The cooler has an integrated multi-voltage power supply with priority
circuit for connecting to an AC voltage source of 100–240 V. The priority
circuit automatically switches the cooler to mains operation, if the
device is connected to a 100–240 V AC mains, even if the 12/24 V
connection cable is still attached.
When switching between the AC mains and the battery supply, the red
LED may light up briefly.
Plug the 100 – 240 V connection cable (Fig
1
3, page 1) into
the AC voltage socket and connect it to the 100 – 240 V AC
voltage mains.
