Safe EMF Distances for AC and DC Circuits

I am planning on installing a transformer, 15KVA 480D/240, transformer within 4 feet of a DCS (Distributed Control System) cabinet which uses 120 VAC and 24 VDC circuits. Is there a safe distance that is required between AC and DC. The power feeds to and from the transformer will be in conduit. I am concerned is that the transformer will induce EMF within 4 feet distance to any of the AC/DC circuits in the DCS (controls) cabinet.

Does anyone have any expertise in this application in terms of AC/DC EMF distances?
