Thank you for your comments. I'm not really trying to do "evaluation
of safety requirements," but, instead, looking for ways we can reduce
costs of the evaluation. Perhaps the use of a UL listed filtered power
inlet, UL listed open frame switching supply, and UL listed power
switch is the best we can do. I was thinking that a "pre-approved"
module that handles all line connected components would help, but
perhaps not.
Again, thanks for the comments!
