Brian, thanks for your input. Can the potential hazard be addresses without English Text which may be misunderstood by those unfamiliar with the language? Wouldn't Symbols Only be better?
John, good point. I hate battling issues with AHJs. We always put at least one such warning label on our instruments just to satisfy them. Dave, I'm not as familiar with the 60950-1 and 60204-1, but since would product is clearly laboratory equipment these standards should not apply. But I am familiar with Inspectors carrying over requirements from one category of products to another. So if AHJs, NRTLs, etc. like to see some kind of warning on the outside of electrical equipment, then won't the Hazardous Voltage Warning symbol alone meet this requirement WITHOUT any Text? As the Machinery Directive states, "Information and warnings on the machinery should preferably be provided in the form of readily understandable symbols or pictograms." And in the case given in the 61010-1 standards, it doesn't say that you have to use Text, but what the warning marking should state. A symbol or symbols can "state" or have the same meaning as text without the concern of the User needing to be able to understand the language of the text. I think we should have a symbol or symbols that satisfies the requirements without text that all authorities can agree on.

Of course that needs to be translated into all appropriate languages too. -Dave From: Kunde, Brian [mailto:brian_ku...@lecotc.com] Sent: Wednesday, April 29, 2015 10:21 AM To: EMC-PSTC@LISTSERV.IEEE.ORG<mailto:EMC-PSTC@LISTSERV.IEEE.ORG> Subject: [PSES] Warning Label: Disconnect from Mains Greetings. We make laboratory equipment designed to the requirements of the IEC/EN/UL/CSA 61010-1 Ed. 3 standard. Most electrical equipment has at least one warning somewhere visible on the outside of the equipment that states something like, "Disconnect Power Before Servicing". Where does this requirement come from? I see no such requirement in the 61010-1 standard. The 61010-1 does say, "If the instructions for use state that an OPERATOR is permitted to gain access, using a TOOL, to a part which in NORMAL USE may be HAZARDOUS LIVE, there shall be a warning marking which states that the equipment must be isolated or disconnected from the HAZARDOUS LIVE voltage before access." However, if our users do not need to gain access inside our equipment, then I assume such warning is unnecessary. We used to have a warning label on any tool assessable panel that has hazardous voltages behind it. However, I do not see this as a requirement in the 61010-1. In the past, we have had inspectors write us up for not having such labels on all panels with hazardous voltage behind it. Does this requirement come from somewhere else? Are the inspectors wrong? The label we commonly use has the Symbol 12 (hazardous voltage warning) and English Text that states something like, "Disconnect Power Before Servicing". However, when our products are sold into non-English speaking countries, we sometimes get dinged for the English Text; especially in French speaking counties. So, if such a label truly is required, can we get away with only using the Symbol 12?, or can we use a label with a combination of symbols, such as Symbol 12 and maybe the ISO 3864-2 Disconnect Mains Plug symbol? Is text of some kind required or can we just use symbols? Any suggestions or recommendations? Thanks to all for your input.
