I agree with Pete for the most part. Be careful in claiming compliance with EN 60204-1, however, as there are still some areas where the harmonization is less than perfect (pilot lights, and operator button colours, among others). Also be aware that EN 61439-1 plus EN 61439-X can also be applied to electrical assemblies under the Machinery directive, and are called out by EN 60204-1.
IMO, if the equipment is already being certified under UL 61010 for example, the only only reason to apply NFPA 79 would be where it is helpful and does not conflict with UL 61010.
