Hi Steve:
The TV broadcast industry electronic products have used two (redundant) AC
sources for their products for many years. You may have some help there.

Subject: [PSES] Multiple electrical power sources
A new question.
A client's product is using two independent AC power sources on a product, but
I can't find anything in 61010-1 60204-1 that provide any guidance on
compliance.
The obvious is that the sections of the product that are fed from source A or B
are not interrelated in any way that would create a hazard for for the other
section, that there be a warning label adjacent to each input that says there
are multiple AC sources, and that each section has it's own circuit protection
and disconnect, even if a facility disconnect is used for both.
What am I missing?
Thanks,
Steve Brody
