Please keep minimum of 2mm clearance (all directions) between inverter high voltage area as marked
on mechanical drawing and any conductors.
Before apply any control signal into inverter, please provide Vcc first. Please follow the reversed sequence
during power off. Power off control signal first, then power off Vcc.
This is an output pin and it is active high (+3V) if any Lamp opens / fails.
