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.

NOTICE! Danger of damage!

When switched off by the battery monitor, the battery will no longer be fully charged. 
Avoid starting repeatedly or operating without longer charging phases. Ensure that 
the battery is recharged.
