COOLMATIC MDC Series
Setting up and connecting the cooling device
29
Connecting to a battery
The cooling device can be operated with a 12 V or 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 fig.

Caution!
Make sure that the polarity is correct.

Before starting up the device for the first time, check whether the
operating voltage and the battery voltage correspond (see type plate).
➤
Connect the cooling device
– As directly as possible to the pole of the battery or
– To a plug socket which is fused 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 connecting the battery to a quick
charging device.
Overvoltage can damage the electronics of the device.
The cooling device is equipped with an electronic device to protect against
reversing the polarity and short circuits when connecting to a battery.
To protect the battery, the cooling device switches off automatically if the
voltage is insufficient (see table below).
