    EMC AND LOW VOLTAGE DIRECTIVES 9.1.2 Installation instructions for EMC Directive The PLC is open equipment and must be installed within a control panel for use.* This not only ensures safety but also ensures effective shielding of PLC-generated electromagnetic noise. * : CC-Link Safety remote station should be used having the control panel installed.

  • Page 60: Cables

    EMC AND LOW VOLTAGE DIRECTIVES 9.1.3 Cables The cables pulled out from the control panel contain a high frequency noise component. On the outside of the control panel, therefore, they serve as antennas to emit noise. To prevent noise emission, use shielded cables when pulling out the cables which are connected to CC-Link Safety master module, MELSECNET/H module, Ethernet module, and CC-Link Safety remote I/O module and using them outside of the control panel.
  • Page 61 EMC AND LOW VOLTAGE DIRECTIVES (2) MELSECNET/H module Be sure to use double-shielded coaxial cables (MITSUBISHI CABLE INDUSTRIES, LTD.: 5C-2V-CCY) for the coaxial cables of MELSECNET/H module. Radiated noise in the range of 30HMz or higher can be suppressed by using double-shielded coaxial cables.

  • Page 62: Power Supply Module

    EMC AND LOW VOLTAGE DIRECTIVES Be sure to use double-shielded coaxial cables for the coaxial cables*2 connected to the 10BASE2 connectors. Ground the double-shielded coaxial cable by connecting its outer shield to the ground Shield Ground here Figure 9.7 SDouble-shielded coaxial cable grounding Refer to (1) for the shield grounding processing.

  • Page 63: Others

    EMC AND LOW VOLTAGE DIRECTIVES 9.1.5 Others (1) Ferrite core A ferrite core has the effect of reducing conduction noise in around 10MHz band and radiated noise in the 30MHz to 100MHz band. It is recommended to fit ferrite cores if shielded cables pulled out of the panel do not provide sufficient shielding effects or if the emission of conduction noise from the power supply line has to be suppressed.
  • Page 64 EMC AND LOW VOLTAGE DIRECTIVES (2) Noise filter (power supply line filter) A noise filter is a component which has an effect on conducted noise. It is not required to fit the noise filter to the power supply line, but fitting it can further suppress noise.

  • Page 65: Requirement To Conform To The Low Voltage Directive

    The Low Voltage Directive requires each device that operates with the power supply ranging from 50 to 1000VAC and 75 to 1500VDC to satisfy the safety requirements. In Section 9.2.1 to Section 9.2.6, cautions on installation and wiring of the MELSEC-QS series PLC to conform to the Low Voltage Directive are described.

  • Page 66: Power Supply

    EMC AND LOW VOLTAGE DIRECTIVES 9.2.3 Power supply The insulation specification of the power supply module was designed assuming installation category II. Be sure to use the installation category II power supply to the PLC. The installation category indicates the durability level against surge voltage generated by a thunderbolt.
  • Page 67 EMC AND LOW VOLTAGE DIRECTIVES (2) Dustproof and waterproof features The control panel also has the dustproof and waterproof functions. Insufficient dustproof and waterproof features lower the insulation withstand voltage, resulting in insulation destruction. The insulation in our PLC is designed to cope with the pollution level 2, so use in an environment with pollustion level 2 or below.

  • Page 68: Grounding

    EMC AND LOW VOLTAGE DIRECTIVES 9.2.5 Grounding There are the following two different grounding terminals. Use either grounding terminal in an earthed status. Protective grounding : Maintains the electrical safety of the PLC and improves the noise resistance. Functional grounding : Improves the noise resistance.

  • Page 69: Chapter10 Loading And Installation

    LOADING AND INSTALLATION CHAPTER10 LOADING AND INSTALLATION In order to increase the reliability of the system and exploit the maximum performance of its functions, this section describes the methods and precautions for the mounting and installation of the system. When a safety PLC detects an error in an external power supply or a fail- ure in PLC main module, it turns off all the outputs.
  • Page 70 LOADING AND INSTALLATION Do not bunch the wires of external devices or communication cables together with the main circuit or power lines, or install them close to each CAUTION other.They should be installed 100 mm (3.94 inch) or more from each other.Not doing so could result in noise that would cause erroneous operation.

  • Page 71: Calculating Heat Generation Of Plc

    LOADING AND INSTALLATION 10.1 Calculating Heat Generation of PLC The ambient temperature inside the panel storing the PLC must be suppressed to an ambient temperature of 55 or less, which is specified for the PLC. For the design of a heat releasing panel, it is necessary to know the average power consumption (heating value) of the devices and instruments stored inside.
  • Page 72 LOADING AND INSTALLATION POINT If the temperature inside the panel has exceeded the specified range, it is recommended to install a heat exchanger to the panel to lower the temperature. If a normal ventilating fan is used, dust will be sucked into the PLC together with the external air, and it may affect the performance of the PLC.
