a
Bonding straps
To connect inactive metal components, bonding straps must be used if
a large surface contact (metal to metal) is not possible. Use only short
bonding straps with large surface areas.Schirmung von Leitungen und
Geräten
b
Supporting bars
All supporting bars that hold control components must have a large-
surface area contact with the cabinet housing.
c
Protective conductor rail
The protective conductor rail must also be connected over a large
surface area to the support bars and has to be connected via an
external cable (cross section of at least 10 mm2) to the protective
conductor system to avoid interference currents.
d
Cable clips
The shielding braid must be held over a large surface area by the cable
clips.
e
Protective conductor system cable (grounding point)
The cable has to be connected over a large surface area with the
protective conductor system.
Shielding of Conductors and Devices
Shielding of Cables
Shielding is used to reduce interfering couplings.
Interference currents affecting the cable shield are fed to ground via
a connection between housings and shield rails. To avoid that the
diverted currents appear again as sources, the shields have to be
connected to the shield conductor with a low impedance.
Conductor types:
Only conductors with a shield braid with a covering density of at
least 80 % should be used. Conductors with film shielding should
not be used because the film can be damaged easily at installation.
