Regarding the understanding that the exterior walls of the control room and cabinet room on the side facing equipment with fire hazards should be walls without any openings, is it not allowed to have openings if the fire separation distance is sufficient?
I mean, is there a distance requirement? Not no matter how far?
Judging from the wording of the clause, of course not. The term \"how far\" you mention is meaningless; if it’s very far, then it has nothing to do with the device, and there’s no talk of addressing fire hazards in such a case.
