Ignition Switch Control with the 7-Seg Display Panel

The 7-Seg Display Panel can be wired to the vehicle ignition circuitry to control operation of the inverter. When the

AC or DC power applied to the inverter and then following these instructions:

Display Panel.

NOTE: Repeat steps 1–5 to turn this feature off again.
