Connecting the cooling unit
Connecting to a battery
The cooling unit can be operated from a 12 V or a 24 V DC voltage supply.
To avoid voltage loss and therefore a drop in performance, the
cable should be kept as short as possible and should not be
interrupted.
For this reason avoid additional switches, plugs or power strips.
➤
Determine the required cross section of the cable in relation to the cable
length according to
h
, page 8.

Caution!
Make sure that the polarity is correct.

Before you start up the unit for the first time, check that the
operatingvoltage matches the battery voltage (see type plate).
➤
Connect your cooling unit
– as directly as possible to the pole of the battery or
– to a plug socket which is fuse protected with at least 15 A (at 12 V)
or 7.5 A (at 24 V).
Caution!
Disconnect the cooling device and other power consuming devices
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 cooling unit is equipped with an electronic system
to prevent polarity reversal. This protects the cooler against short-circuiting
when it is connected to a battery.
