Connecting to a battery
The cooling unit can be operated from a 12 V or a 24 V DC voltage supply.

➤ Determine the required cross section of the cable in relation to the cable length
according to fig. h, page 8.

➤ Before you start up the unit for the first time, check that the operating voltage
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).

For safety reasons the cooling unit is equipped with an electronic system to prevent
polarity reversal. This protects the cooling unit when it is connected to a battery.
NOTICE!
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.

NOTICE!
Make sure that the polarity is correct.
NOTICE!
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.
