Bill, The first question I would have is whether your equipment is properly classified as industrial electrical equipment or laboratory equipment. If it’s lab equipment, then EN 61010-1 is a good choice. If not, then EN 60204-1 is the more correct choice.
The question regarding e-stop needs to be based on your risk assessment – does the RA dictate a need for an e-stop system? Can you in fact control the hazards adequately without an e-stop? If the answer is YES, then no emergency stop system is required. If NO, then an e-stop is required and should be installed. -- Doug Nix, A.Sc.T.

It's been my (EU) interpretation that in satisfaction of the Low Voltage Directive, the scope of the Safety of Machinery standard (EN60204) applies to equipment with at least one moving part. My employer designs electrical equipment (power supplies) in which there are no moving parts. Thus, I've selected and have been reading EN61010 as our safety standard. We provide a circuit breaker (ON-OFF), a power off button (function START-STOP) and a safety-interrupt loop connection (<24Vdc) which is available for the user to attach their OFF switch; each of these methods halt power output. I see no explicit requirement for an embedded or built-in EStop under EN61010; does anyone else interpret this differently?
