R. Red wire for 24 Volts direct current
Bk. Black wire for ground
Bl. Blue wire for IPC+ connection

Make sure all devices and LLIDs are connected together in
some way. Use the correct cables so that you don't have any
open plugs when finished. Avoid placing wire ties directly over
plug connectors. This may press on the locking mechanism
and over time the plugs may release.
