If the start up voltage falls below Cold Cath ode Tube st rike volta ge, the CCFL will not light up easily specially at
lower ambient tempera ture. Please revi ew mounting ins truction to avoid any abnorma l operation due to
coupling/leakage cap aci tan ce of inver ter high voltage area to any surround ing conduct or.
Please check your lamp char acteristic for minimum operational current and set the limit poi nt in your design to
avoid flicker ing and/ or abnorm al operat ion.
For proper opera tion of circuit protecti on (fuse or IC PROT ECTO R ),Ple ase use m inimum of 10.0A capaci ty for input
power suppl y.
Imp edenc e from the wire conn ec tion can cause a ripple in the input. The product has an internal fuse
of 5.0A. Please check that input cu r rent peak wave form does not exceed 5. 0A .
