1. If the product is applied to high voltage condition (higher than 40V),

the input terminal must be provided with an additional capa-

citor

(≥47µF/100V) to prevent voltage spike from damaging the module.

2. The output cathode cannot be connected with the input grounding,

or

it will damage the module.
