￫
Route mains and motor cables in the control cabinet as close to
the ground potential as possible. This is because free moving
cables act as antennas.
￫
If routed in parallel, cables carrying high frequencies (e. g.,
screened motor cables) and clean cables (e. g., mains supply
cable, control and signal cables) should be installed at a distance
of at least 100 mm from each other in order to avoid
electromagnetic interference. You should also use separate
cable entries if there is a great difference in voltage potentials.
If control cables and power cables need to cross, they should
always do so at right angles (90°).

Never lay control or signal cables ② in the same duct as power
cables ①.
Analog signal cables (measured values, setpoints, and
correction values) must be routed inside shielded conduits.
