Operation
6.4 Using the battery monitor
The device is equipped with a multi-level battery monitor that
protects your vehicle battery against excessive discharging when
the device is connected to the on-board 12/24 V supply.
If the cooler is operated when the vehicle ignition is switched off, the cooler
switches off automatically as soon as the supply voltage falls below a set
level. The cooler will switch back on once the battery has been recharged to
the restart voltage level.
A
NOTICE! Danger of damage!
When switched off by the battery monitor, the battery will no longer
be fully charged. Avoid starting repeatedly or operating current
consumers without longer charging phases. Ensure that the battery
is recharged.
The switch-off and switch-on points measured at the connection terminals of
the compressor are listed in the following table:
Battery monitor mode
Switch-off voltage at 12 V
Restartvoltage at 12 V
Switch-off voltage at 24 V
Restart voltage at 24 V
6.5 Using the cooler
A
NOTICE! Danger of overheating!
Ensure at all times that there is sufficient ventilation so that the
heat that generated during operation can dissipate. Ensure that
the ventilation slots are not covered. Make sure that the device
is sufficiently far away from walls and other objects so that the
air can circulate.
➤ Place the cooler on a firm foundation.
Make sure that the ventilation slots are not covered and that the heated
air can dissipate.
