Hello group, I am a novice to medical grade electrical equipment requirements so it is quite likely my query is one that has received responses on this forum time and time again. You will be pleased to note that I received the 'relevant sections' of the standard EN 60601 this morning, and the Forklift truck that dropped them off has left the premises (so I jest, but they might as well have been delivered by Forklift!.. I didn't realise the standard was that size! ).
Query Are there any UL standards I should be looking at in conjunction with EN 60601? I have been looking at commercially available medical grade PSU's and I find the 5-way DIN connector extensively used. Is this the preferred connector? If so which standard should I be looking at to design the mating part? If not, is there a section of the standard which recommends connector types? The 5-way DIN connector from different manufacturers appears to have the same pin assignments. Is the metallic ring around the pins assigned a function such as Earth etc? No manufacturer I have looked at seems to have this explained. If the ring around the 5-way DIN is not used for earthing (grounding) is there a requirement for DC powered equipment to be earthed, and if so, how is this achieved? I need to include an indicator (l.e.d.) for a 'power on' condition. Does EN 60601-1, Clause 6.7 apply ( i.e. Red, Yellow, Green and other for such a function )?. Your help is much appreciated, and thanx in advance.
