Note
: Make sure that the positive and negative poles of the charger are connected correctly to the
positive and negative poles of the power supply. If the positive and negative poles are reversed, the
charger will not be damaged, but it will not start. Connect the red cable of the charger to the positive
pole of the power supply, and connect the black cable of the charger to the negative pole of the power
supply. Please refer to the below picture:
3.1.2 Battery power supply
If the charger is battery powered, please set SUPPLY in the menu to "BATTERY".
The battery power supply of the charger must be with the voltage of 10.5-15V. The following picture
uses the car battery power supply as a reference. When the car battery is used for power supply of
the charger, the lowest working voltage need to be set on the menu LOW PWR of the charger to
prevent the car battery from being unable to start the car due to lack of power.
