Hi Brian,
This is my bailiwick. If you are talking about semiconductor manufacturing
equipment, the correct standard is IEC 60204-33. If it’s standard manufacturing
machinery, then it’s IEC 60204-1. Clause 18 calls out 1 kV or 2x nominal mains
voltage, whichever is more for the “voltage test” (
t your machine without the PSU connected, assuming the PSU has a 3rd
party certification for electrical safety.

I understand that commercial products are %100 HiPot tested at the factory.
Does this rule hold true for 3-phase industrial machinery?
Here is why I am asking. I just pre-tested a German build 400-480Vac to 24Vdc
power supply
