 Applicable Wire Sizes
Tabl e 2.7 shows the wire size of each terminal. Select an appropriate wire size considering the current capac-
ity.
* Use shielded twisted-pair wires to input an external frequency reference.
 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.
