The Control4? Terminal Blocks mount in a Control4? Panelized Lighting Panel (C4- DIN-5PAN or C4-DIN-2PAN) and are used to terminate field wiring (Line, Neutral, and Load) for each circuit in a Panelized Lighting system. Installed adjacent to 8-Channel Dimmer, 8-Channel Relay, 8-Channel 0-10V Dimmer, Bus Power Supply, or 8-Port Ethernet Switch modules, terminal blocks provide the appropriate connections for each module type. Terminal blocks are sold separately from modules to allow for termination of field wiring during the rough-in phase. All modules can then be installed and wired to the terminal block during the trim-out phase.
