Please keep a minimum of 2mm clearance in all directions between inverter high voltage areas
and any conductors as marked on mechanical drawing.
Dimming range 30% - 100% ≙ 0R ~ 10k; 10k = 100% brightness.
Please provide Vcc before applying any control signals into inverter.
Revere the sequence during power off which is control signal off first then Vcc.
Common current for both CCFL.
