If only one signal cable needs to be
connected, block unused cable holes
using plugs and tighten cable glands.
Installing the RS485 Communications Cable
3.5
• When laying out the signal cable, separate it from the power cable and keep it away from strong
interference sources to avoid strong communication interference.
• Ensure that the protection layer of the cable is inside the connector, that surplus core wires are
cut off from the protection layer, and that the exposed core wire is totally inserted into the cable
hole and the cable is connected securely.
• For details about the JX01 terminal block of the 10-in 1-out SmartACBox, see page 15.
