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
