Our NRTL asks for the warning "No User Serviceable Parts Inside" when that is the case but that is relative to products complying with UL/EN 60950-1 and EN 60204-1. Of course that needs to be translated into all appropriate languages too.

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.
