You can drill an accurate panel cut-out size 2.09*1.26*1.18 inch proper place of equipment for installation; 2 power connection diagrams to be chosen: direct & key switch.

Must connect the "C" pin with positive(+) pin to keep the indicator getting an normal real-time battery power left.

NOTE:

1.Make sure to apply the proper voltage on the indicator. Failure to apply the proper voltage will cause the indicator not to work normally.

2.Make sure that the C terminal is connected to the battery positive terminal or the C terminal is connected to the battery positive terminal through the key switch. If the C terminal is not wired correctly, the device will not work properly. (LED indicator will not light up)

3. If the voltage of the DIP switch is set lower than the actual voltage of the battery, the device will not be damaged, and it can work normally if it is reset to the correct voltage value.
