Group 3: cables that are a source of interference, such as control cables for
inductive loads and motor brakes
°
Group 4: cables that are a powerful source of interference, such as out‐
put cables from frequency inverters, welding system power supplies, power
cables
b
Cables in groups 1, 2 and 3, 4 must be crossed at right angles (
b
Route the cables in groups 1, 2 and 3, 4 in different cable channels or use
metallic separators (
and
). This applies particularly
if cables of devices with a high level of radiated emission, such as frequency
converters, are laid parallel to device cables.
