Running cable in a duct

Make sure to separate high-interference cables from equipment susceptible to interference.

Cable types

  • Cable causing interference: Motor cables, especially motors used with VSDs, energy cables

  • Cables susceptible to interference: Control cables, low-voltage cables, interface cables, LAN cables, digital and analog signal cables

Cable segregation

  • You can run both types of cable in the same duct, but in different compartments

  • If ducting with 3 closed sides and a partition is not available, separate the interference-emitting cables from other cables by a minimum of 150 mm, or route in separate ducting

  • Cross high-interference cables with equipment susceptible to interference only at right angles

  • If, in exceptional cases, signal and interference-emitting power cables are run in parallel, the risk of interference is high. In that case, limit the cable length of the DC 0...10 V positioning signal line for modulating actuators
