Wiring Notes: 1. 485 communication lines must use shielded twisted pair, preferably multiple strands as spares, with a maximum length of 2500 meters. 2. Wiring should be as far away as possible from high-voltage wires, not parallel to power lines, and not bundled together. 3. The 485 bus must have a hand-in-hand bus structure, and star connection and bifurcation connection must be eliminated. 4. If there are more than 30 controllers or the cable length is greater than 500 meters, it is recommended to use a 485 repeater. 5. AC-powered equipment and the chassis must be grounded and well-grounded. 6. Connect the GND ground of all 485 devices with shielded wires.
