I have a 240/480v Pri, 120v Sec. stepdown transformer fed from a 480/60Hz/3phaze power supply. Do i ground my neutral from the trans. or leave it "floating" and keep my ground separate from the neutral completely?

I have a NEC 2002 code book also so if some one could give me a ref. in the book also would be nice. Thanx in advance
