Best practices for telcoflex -48VDC cabling & other power OSI layer 1

Hey all, I'm looking for a document or set of photos/presentation on best practices for telcoflex/-48VDC power cabling installation. Labeling, routing, organization and termination, etc. Or a recommendation on a printed book that covers this topic. Not necessarily fully oldschool "we're going to teach all the technicians how to do the kansas city stitch" stuff, but the sort of thing that's applicable in a modern colo/IP network environment.
