Note 1.

For circuit connection, please prefer to test circuit diagram.

Note 2.

Please use minimum of 2mm clearance (all directions) between inverter high voltage area and any

conductors. Please refer to mechanical drawing for marking of high voltage area.

Note 3.

Open voltage (strike voltage) is measured across the transformer secondary winding at no load as the

reading at the output connector would be less than the actual value.

Note 4.

If the start voltage falls below Cold Cathode Tube strike voltage, the CCFL will not light up easily

specially at lower ambient temperature. Please review mounting instruction to avoid any abnormal

operation due to coupling/leakage capacitance of inverter high voltage area to any surrounding

conductor.

Note 5.

Please check your lamp characteristic for minimum operational current and set the limit point in your

design to avoid flickering and/or abnormal operation.

Note 6.

For proper operation of circuit protection (FUSE or IC PROTECTOR), please use minimum of 2A

capacity for input power supply.

Note 7.

The warning signal: 5V in abnormal circumstances.

Note 8.

The brightness of the lamp changes at the change and this level, too, when the direction cjanges the

input voltage lower than 12V of the standard.

Note 10.

In test circuit, if one of the switches CN2 or CN3 opens, then the warning signal will be activated (+5V).
