The tests were conducted by Mitsubishi Electric Corporation using a control panel having damping
characteristics of 37dB (maximum) and 30dB (average) (measured at 3m distance, 30 to 300MHz).
(b) Power cable and ground cable
(3) CC-Link IE Field Network cable
The precautions for using CC-Link IE Field Network cables are described below.
• For CC-Link IE Field Network module, use CC-Link IE Field Network cables (SC-E5EW-SM, manufactured
• A CC-Link IE Field Network cable is a shielded cable. Strip a part of the jacket of the cable as shown below
• Use shielded cables for external wiring and ground the shields of the shielded cables to the control panel

• Keep the diameter of the holes on the control panel to 10cm or less. If the diameter is larger than 10cm,
electromagnetic wave may leak. In addition, because electromagnetic wave leaks through a clearance
between the control panel and its door, reduce the clearance as much as possible. Use of EMI gaskets
(sealing the clearance) can suppress undesired radiated emissions.
• Provide a ground point to the control panel near the power supply module. Ground the LG and FG
terminals of the power supply module to the ground point with the thickest and shortest ground cable
possible (30cm or shorter).

with an AD75CK cable clamp (manufactured by Mitsubishi). (Ground the shields within 20 to 30cm from the
module.)
