Group 3: Cables which are a source of interference, such as control cables
for inductive loads, motor brakes
°
Group 4: Cables which are powerful sources of interference, such as output
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
Cables in groups 1, 2 and 3, 4 must be routed in different cable channels or
metallic separators must be used,
. This applies
particularly where cables of devices with a high level of radiated emission,
such as
frequency converters, are laid parallel to sensor cables.
