Hi! We have in a long-term discussion that we could not clear the point with some NotifiedBody. There is a ME1 device which is connected to mains plug (230 V - 50 Hz input) and totally reinforced insulated. The sample (ME2) is connected to a port on ME1 with 24 V DC.(ME2 is supplied via ME1) ME2 structure is also completely reinforced. A notified body claims that there is no classification for ME2. We think that the ME2 is also Class II. ( SELV is not a protection for 60601-1 according to Annex A. and there is no state for exemption.) Any ideas/experiences???
