Lisa - While I can't speak directly to the case in EN61326, this sounds a lot like the concept of a centralized dc power system, as addressed in UL1459 and carried over into CSA950/UL1950 and working it's way into IEC60950 as a dc mains supply (there is only reference in IEC60950, Third Edition, for instance, in the notes to Table 5B).
If this is intent of EN61326, you can refer to CSA 22.2 No. 950/UL1950 Third Edition, Annex NAB. It's essentially the same as an ac power distribution system in a building. Regards, Peter L.

It is referred to in EN 61326 and I need some clarification. Thank you in advance. Regards, Lisa
