Yes, you may do it. AFAIK, NEC does not apply much for wiring INSIDE a control panel except for motor controllers, over current protection and a few other things, however NFPA70 does.

About the only NEC code you might violate is often quoted 110.3(B): Installation and Use. "Listed or labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling."

Which simply means that the manufactures directions can't be violated. Like if you have only one terminal on the P/S and the mfg. says to place only one wire there and you place two wires under the terminal, that would violate the listing.

That said, sometimes ya got to do what ya gots ta do. As long as it's safe.

Don't forget to add wires to the 0v return to the P/S.
