You wire the screw terminals on a Non-isolated RS-485 Adapter to connect a BACnet/IP controller to a BACnet MS/TP (RS-485) network. Always use the recommended wires (or wires with larger cross-sectional area).
Loosen the screw of the terminal.
Strip approximately 7 mm (0.3 inch) of the insulation from the end of each wire.
Insert the end of the wire fully into its intended terminal. Ensure that no bare wire strands extend from the terminal.
Tighten the screw using a small flat-blade screwdriver. Ensure that the screw is fully tightened. Use the following recommended screw tightening torque: 0.5 Nm (4.5 lbf.in).
Repeat steps 1 to 4 until all screw terminals on the Non-isolated RS-485 Adapter are correctly wired. For more information, see Non-isolated RS-485 Adapter Connection and Wiring .
Follow the recommendations and guidelines for the RS-485 interface configuration in regard to biasing, termination, cable selection, cable length, and cable routing. For more information, see RS-485 Communications .
Use appropriate cable strain relief methods, to help prevent any load applied to the cable from being transferred to conductor terminations.
