4.1 Applicable Cable and Connector
The following table shows the applicable cable and connector for a PROFIBUS-DP network.
DESIGN PRECAUTIONS
• Make sure to observe the following precautions in order to prevent any damage to the machinery or accidents
due to abnormal data written to the PLC under the influence of noise:
1) Do not bundle the main circuit line together with or lay it close to the main circuit, high-voltage line, or load
line. Otherwise, noise disturbance and/or surge induction are likely to take place. As a guideline, lay the
control line at least 100mm (3.94") or more away from the main circuit, high-voltage line, or load line.
2) Ground the shield wire or shield of the shielded cable at one point on the PLC. However, do not ground them
at the same point as the high-voltage lines.
• Install module so that excessive force will not be applied to peripheral device connectors.
Failure to do so may result in wire damage/breakage or PLC failure.
WIRING PRECAUTIONS
• Cut off all phases of the power supply externally before installation or wiring work in order to avoid damage to the
product or electric shock.
WIRING PRECAUTIONS
• When drilling screw holes or wiring, make sure cutting or wire debris does not enter the ventilation slits.
Failure to do so may cause fire, equipment failures or malfunctions.
