Integrity of protective circuits and grounding.

Environmental conditions (ambient temperature, humidity, indoor vs. outdoor installation). Protection against dust, water, and mechanical impact

Mandatory inspection and testing of every completed assembly before leaving the factory to ensure it matches the verified design. Interface Characteristics: Definitions of rated voltage ( Uncap U sub n ), rated current ( Incap I sub n ), rated frequency ( ), short-circuit current ( Icccap I sub c c end-sub ), and IP rating (protection against dust and moisture).
