I am trying to find out if it is required to post the source of power to a disconnect in an industrial application. I was using the new NEC App searching with key-words but could not find anything.

Identification of the source of power by anything other than on a 'one-line drawing', is up to individual company's Electrical Safe Work practices (see OSHA and NFPA70E documentation requirements).
