Connecting to a battery
The cooling device can be operated with a 12 V to 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 if this is possible.
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 6, page 4.
