6.5.2 Shielding
Shielding measures reduce noise energy (immunity of adjacent systems and devices to ex-
ternal 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 terminals provided or
should be connected to the connector housing.
} Use cables with braided shield, 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.
