Precaution
10. Safety Indication:
Some electrical circuits or device related materials require
special attention to their safety features, which cannot be
viewed by the naked eye. If an original part is replaced with
another irregular one, the safety or protective features will
be lost even if the new one has a higher voltage or more
watts.
Critical safety parts should be bracketed with ( ,
only regular parts for replacements (in particular, flame
resistance and dielectric strength specifications). Irregular
parts or materials may cause electric shock or fire.
11. Pay additional attention to the current leakage as the
voltage between the power board and the ballast is 220 to
440V, i.e. very high. And also beware of possible electric
shock from the primary power source.
