I would like your opinion on the application of the following: IEC 61010-1 6.5.2.3 PROTECTIVE CONDUCTOR TERMINAL f) Plug-in type PROTECTIVE CONDUCTOR TERMINALS combined with other TERMINALS and intended to be connected and disconnected without the use of a TOOL, shall be designed so that the protective conductor connection makes first and breaks last with respect to the other connections. Examples include plugs and appliance couplers for MAINS cords and connector assemblies of plug-in units.
Does the term, "intended to be connected and disconnected . . ." mean during normal operation or normal condition? Does this section apply to connectors that are connected during the initial installation and is not ever intended to be disconnected unless the equipment is being disassembled or serviced? We have an application where Unit A supplies AC Mains and PE conductor to Unit B along with other conductors in one multi-contact connector. But Unit B would never be disconnected from Unit A while Unit A was power up. The connector we want to use has a locking ring but it does not require a tool to disconnect. Having the PE terminals mate first and break last would be a challenge. If this rule does apply, can I get around the "makes first and breaks last" requirement in the connector by putting a warning label near the connector to "Disconnect Power Before Removing Connector", or something like that.
