The standard reads "for each supply ". I was assuming this was referring/allowing for multiple concurrent supplies on the same machine. You think it was referring to different options for a single supply? For example ratings for 1 single phase 60Hz supply or 1 single phase 50Hz supply or 1 3 phase supply?
My first thought before reading the standard was to put everything required on one nameplate only including only the primary power supply ratings located adjacent the primary power input. A secondary rating plate would go adjacent the second power input with only the supply ratings on it. Duplicating the serial number and CE mark seemed wrong to me at first but after thinking about it I guess it would be OK. I could not find anything regarding whether or not multiple CE marks were OK for the same product. -Dave -----Original Message----- From: John Woodgate [mailto:j...@jmwa.demon.co.uk] Sent: Wednesday, July 02, 2014 12:54 AM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] Multiple power sources In message <f3d590e5d0f24f56b4539e9d93d57...@bn1pr08mb059.namprd08.prod.outlook.com> , dated Tue, 1 Jul 2014, "Nyffenegger, Dave" <dave.nyffeneg...@bhemail.com> writes: >Does this mean for a machine with two incoming supplies (separated by >some distance) a nameplate containing the ratings for both power >supplies needs to be on both nameplates adjacent both supplies?

It appears that the standard does not consider the case of multiple supplies in this clause (if at all). So you have to consider what to do and document your decision in the safety assessment document. If you can put everything about both supplies on both nameplates, you could hardly be criticized. -- OOO - Own Opinions Only. With best wishes. See www.jmwa.demon.co.uk Quid faciamus nisi sit?
