Grounding and UL 508A Standards
The debate over grounding power supplies is likely to be ongoing, with some engineers preferring the removal of ground loops and ensuring isolation by keeping DC power supplies
Attach a ground wire from one of the threaded studs (A) at the bottom of the housing, to the mounting plate (B). This helps to reduce the potential difference that exists between conductive parts and the earth. Equipment Protection: Grounding protects substati...
