Control Circuit Wiring Precautions

Observe the following precautions when wiring control circuits.
Separate the control circuit wirings from the analog I/O (Terminals L1 to L9) wirings, relay sequence I/O
•
(Terminals 1 to 40) wiring, other power lines and power supply lines.
Use shielded twisted-pair cables for analog I/Os (Terminals L1 to L9) to prevent malfunctions caused by
•
noise.
Lay the shielded wires so that they will not have contact with other signal lines and devices.
•
Tighten the screws with the specified tightening torque.
•
Use closed-loop crimp terminals to connect cables to the terminal block.
•
Use a Phillips screw driver to tighten terminal screws.
