I have done it both ways but prefer to leave it ungrounded. I've never seen grounding solve a problem with noise or anything else. Not that I doubt that other people have.

Also it would seem to be hazardous to our delicate 24VDC electronics in the event of a major ground fault of nearby high voltage equipment.
