Please keep a minimum of 2mm clearance in all directions between inverter high voltage areas
and any conductors
Please provide Vcc before applying any control signals into inverter.
Reverse the sequence during power off which is control signal off first then Vcc.
Resistor dimming: 10kΩ – max. luminance.
Option: CCFL – fail signal
