1) Ground the cables at a position within 30cm (11.82inch) from the module with the cable clamp, etc.
2) Wire the power supply cable as short as possible using the twisted cable (2mm
3) Use the shielded twisted cable (cable length: 30m (98.43ft.) or less) for each I/O signal cable.
4) Wire the cable connected to secondary side of 24VDC power supply module as short as possible in the control panel.
(Cable length: 30m (98.43ft.) or less)
5) Wire the power supply and 24VDC power supply as short as possible using the cable of approx. 2mm
the control panel.
6) CC-Link IE Field Network cable is fixed with bundle material, etc. to grand side such as a wall of the control panel.
Do not wire the cable in the air.

amplifier and the communication cable such as an expansion cable or a network
cable must not be mixed. In the duct, leave 10 cm (3.94 inch) or more between
the power line and the communication cable, and separate using a separator
(made of metal), etc. It is required in the same control panel as well.
Mixing the power line and communication cable may cause increase of noise or
malfunction due to noise influence.
