RSS up & working - questions about NEC labeling and signage.

Options
We went with the MidNite Solar Birdhouse-1 UL listed Rapid Shutdown System (RSS) with one Birdhouse, a combiner/shutoff box with power supply board, and an MNBDM battery disconnect module in the E-panel. The Birdhouse has some signage, but how much more do I really need? I saw an NEC poster that had literally labels on every stick of conduit, and raceway not to mention many mentions of don't touch, and electricity hot (:-))
