Communication Function Connection Diagram(PLC Connection Diagram)

Notes: 1)	Shield wire To prevent current flow along shield sections, ground one end of the shield wire. (If both ends of the shield section are grounded, a closed circuit with the earth will form and electricity flowing through the shield wire will cause increased susceptibility to noise.)
2)	Terminating Resistors (Terminators) The KT4H / KT4B series has a built-in pull-up resistor or pull-down resistor. For this reason, do not connect the terminating resistor on the communication line.
