Open circuit on all lamps for more than 3 sec., will shut the inverter down. 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 (+5V) if any lamp opens / fails.
