  • Page 44 (2) Installation inside a control panel The programmable controllers are open type devices and must be installed inside a control panel. This ensures safety as well as effective shielding of programmable controller-generated electromagnetic noise. *1 Modules on the remote station in each network must be also installed inside the control panel.
  • Page 45 Note the following when using cables for the CC-Link IE Field Network. • Be sure to use the cables for the CC-Link IE Field Network (SC-E5EW-SM, manufactured by Mitsubishi Electric System & Service Co., Ltd.). • Shielded cables should be used for the CC-Link IE Field Network.
  • Page 46 (4) Cables used for the modules connected to the head module Use shielded cables for the cables which are connected to the I/O modules and may be extended out of the control panel. If a shielded cable is not used or not grounded correctly, the noise immunity will not meet the specified value.
  • Page 47 (b) Grounding the twisted pair cable • Always use shielded twisted pair cables for connection to 10BASE-T and 100BASE-TX connectors. For the shielded twisted pair cable, strip a part of the jacket as shown below and ground the exposed shield section in the largest possible area.
  • Page 48 (d) Grounding the cable clamp Use shielded cables for external wiring and ground the shields of the external wiring cables to the control panel with the AD75CK-type cable clamping (Mitsubishi). (Ground the shield section 20 to 30cm away from the module.) Inside the control panel 20 to 30cm AD75CK...

  • Page 56 (14) Others (a) Ferrite core A ferrite core has the effect of reducing radiated noise in the 30MHz to 100MHz band. It is recommended to attach ferrite cores if shield cables coming out from pulled out of the control panel do not provide sufficient shielding effects.
  • Page 57 (b) Noise filter (power supply line filter) A noise filter is a component which has an effect on conducted noise. Attaching the filter can suppress more noise. (The noise filter has the effect of reducing conducted noise of 10 MHz or less.) The precautions for attaching a noise filter are described below.

  • Page 58: Requirements To Compliance With The Low Voltage Directive

    (c) Isolation transformer An isolation transformer has an effect on reducing conducted noise (especially, lightning surge). Lightning surge may cause a malfunction of the programmable controller. As measures against lightning surge noise, connect an isolation transformer as shown below. Using an isolation transformer will reduce an impact of lightning.
  • Page 59 (2) MELSEC-L series module selection (a) Power supply module There are dangerous voltages (voltages higher than or equal to 42.4V peak) inside the power supply modules of 100VAC and 200VAC rated input voltages. Therefore, for CE-marked products, insulation is reinforced internally between the primary and secondary circuits.
