  • Page 14: Electromagnetic Compatibility (Emc)

    Electromagnetic Compatibility (EMC) Overview The safety system is designed to be installed within an electromagnetic industrial environment. To ensure electromagnetic compatibility the correct procedures must be carried out when installing the system. A device is electromagnetically compatible if: • It functions without error in a given electromagnetic environment. •...

  • Page 15: Making The Installation Emc-Compatible

    Electromagnetic Compatibility (EMC) • Capacitive (electrical) coupling A different potential between the source and interference sink (e.g. two cables) creates an electrical field. Cross-coupling is proportional to the rate of voltage change. Possible sources of interference are contactors, static discharge, parallel signal cables.

  • Page 16: Cabling

    • The housing should be connected to the earth conductor “PE”. A cable cross section of at least 2.5 mm should be used. Connections should be kept as short as possible. • Always connect the earth conductor “PE” to the central earth point in star form.

  • Page 17: Equipotential Bonding

    Electromagnetic Compatibility (EMC) • Data and signal lines should be laid as close as possible to an earthed surface. Cabling to open air systems: • As far as possible use metal conduits. These should be electrically connected and earthed. • Ensure there is sufficient protection against lightning by: - Using metal conduits earthed at both ends, or concrete cable ducts with reinforcements connected across the joints.

  • Page 18: Screened Cables

    Screened cables Interference currents arising from electrical, magnetic or electromagnetic fields of interference must be diverted to cable screens via the earth bars connected to the enclosure. Please remember the following: • Connect the screens with low impedence to the earth conductor. •...

  • Page 19: Miscellaneous

    Electromagnetic Compatibility (EMC) Miscellaneous Connecting the programming device The programming device requires a mains connection in each cabinet. The mains connection must be connected to the same distributor as the earth conductor for the cabinet. Lighting inside the cabinet Use low interference panel lighting for inside the control cabinet. NOTICE Fluorescent lamps should be avoided as they create interference fields.

  • Page 28: Notes On Wiring

    Notes on wiring Where safety-relevant applications are concerned, it is essential that short circuits and line breaks are unable to cause a hazardous condition within a plant. The way in which this is done will depend on the degree of hazard within the plant itself, the switching frequency of the input devices and the level of safety of the input devices and actuators.
