(2) Grounding cables using a cable clamp
Use shielded cables for external wiring of the following modules, and ground the shield section of the shielded
cable to the control panel using the AD75CK cable clamp (Mitsubishi). (Ground the shield section within 20 to
30cm from the module.)
• CC-Link IE Field Network module
• Positioning module
• Channel isolated pulse input module
• Multichannel high-speed counter module
• Loop control module
• Load cell input module
• Temperature control module
• 4Mpps capable high-speed counter module
• Multi function counter/timer module
• Analog I/O module
The AD75CK enables up to four cables to be grounded together if the outside diameter of the shielded cable is
about 7mm.
For details of the AD75CK, refer to the AD75CK-type Cable Clamping Instruction Manual.
(3) MELSECNET/H module
Always use a double-shielded coaxial cable (MITSUBISHI CABLE INDUSTRIES, LTD.: 5C-2V-CCY) for the
coaxial cables MELSECNET/H module. Radiated noise in the range of 30HMz or higher can be suppressed by
using double-shielded coaxial cables. Ground the double-shielded coaxial cable by connecting its outer shield to
the ground.
Refer to (1) for the grounding of the shield.
