Connecting the device to a battery
The device is operated with a voltage of 12 V DC:
Caution!
e
To avoid voltage drops and loss of performance, keep the cable as
short as possible and avoid joins.
For this reason avoid additional switches, plugs or multi-way
adapters.
➤ Determine the required cross section of the cable in relation to the cable
length according to fig. 8, page 6.

Caution!
e
When connecting the battery, observe the correct polarity.
Before starting up the device for the first time, check whether the operat-
ing voltage and the battery voltage match (see type plate).
➤ Connect your device
– as directly as possible to the poles of the battery or
– to a fused socket with at least 15 A.
Caution!
e
Disconnect the refrigerator and other electric loads from the battery
before connecting the battery to a quick charging device.
Overvoltage can damage the electronics of the device.
For safety reasons the device is equipped with an electronic system to pre-
vent polarity reversal. This protects the device against short-circuiting when
it is connected to a battery.
Only MR-07: To protect the battery, the device switches off automatically if
the voltage is insufficient (see table below).
