How to Install the 302X-120-240 Controller
This guide provides step-by-step instructions for installing and configuring the 302X-120-240 controller, ensuring proper wiring and setup for optimal performance.
Estimated time: 45m
Tools needed:
Screwdriver, Wire strippers, Multimeter
Supplies needed:
Mounting screws, Terminal connectors, Conduit plugs
- Mount the controller
Remove the cover by unscrewing the two screws. Position the rear of the housing against the mounting surface and mark the drilling positions using the mounting holes as a template. Secure the unit using appropriate screws for the surface type.
- Make electrical connections
Route the power wires through the 1/2" threaded openings into the unit. Connect the power source wires to the appropriate terminals: for 24V models, connect positive to (+) and negative to (−); for 120V and 240V models, connect hot to 'L' and neutral to 'N'. Ensure all connections are tight and secure.
- Install tone and speaker connector cards
Plug the desired tone card into the designated socket and ensure the rubber gasket is seated properly. For audio signal leads, connect them to the speaker connector card inputs and plug the card into the socket. Reinstall the housing cover and tighten the screws to secure it.
