When installing the control system, therefore, observe the following five basic rules. When installing the programmable controllers, provide large-area good quality grounding of the inactive metal parts (see Section 3.2).
  • Page 37 Principles of Installation of Systems for EMC • • Provide the line shields with a large-area connection to a shield/protective conductor bar immediately after the cabinet inlet, and secure the shields with cable clamps. Route the grounded shield as far as the module without interruption, but do not connect the shield there again.
  • Page 38: Installation Of Programmable Controllers For Emc

    Installation of Programmable Controllers for EMC Installation of Programmable Controllers for EMC Measures for suppressing interference voltages are often applied only when the control system is already operational and proper reception of a useful signal is impaired. The reason for such interference is usually inadequate reference potentials caused by mistakes in equipment assembly.
