Each level of protection controls disabling of the unit in given range of battery voltage as shown
at below table.
12V CUT-OUT
LOW 10.2V
MED 10.7V
HIGH 11.7V
When the unit is connected to the car, we suggest to set protection to HIGH level. MID and LOW are
suggested to use when the unit is connected to the backup battery. Different cars may have different
power output voltage.
Most cars will stop the power supply if engine is stopped. But some cars will continue power supply
even when engine is stopped. If your refrigerator is still working when the engine of the car is stop-
ped, then you should adjust the battery protection to HIGH, otherwise, the power of your car battery
may run out and your car battery may not have enough power to start the engine.
