Note 1. Note 2.
For circuit connection, please prefer to test circuit diagram. 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. 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. If the start up 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. For operation in non-isolated configuration, please connect CN2-3 (V-Low) to input return (GND) as the output of DC/AC inverter is electrically isolated from input. For proper operation of circuit protection (FUSE or IC PROTECTOR) of CXA-L0505-NJL, please use minimum of 2A capacity for input power supply and 1A for CXA-L0512-NJL and CXA-L0524-NJL..
