][EMV_Schirmung
Shielding measures reduce noise energy (immunity of adjacent systems
and devices to external influences):
Correct shielding of the following cables avoids interference coupling
with
– Motor cables
– Cables to the external brake resistor
– Encoder cables
– Cables with digital and analogue signals
– Cables to communications interfaces
All shielded cables are to be attached at both ends to the shield ter-
minals provided or should be connected to the connector housing.
Use cables with braided screening, with a minimum cover area of 80
%.
Any interruptions to the shielding e.g. at terminals, contactors,
chokes, should be bridged at low impedance over a wide area.
All connectors or sockets should be fastened with screws to ensure
ample, conductive contact between the braided shield and the front
plate.
