6.5.2 Shielding
Shielding 6- ][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.

Remove the outer cable sheath and
the braided shield to the required wire
length. Secure the wires with a cable
tie.
Remove the outer cable sheath to a
length of approx. 30 mm. Be careful
not to damage the braided shield.
Strip all the wires and fit end ferrules.
Use the cable ties to attach the cable
to the shielding plate on the side (1) or
bottom (2) of the servo amplifier.
Press the cable's braided shield firmly
against the shielding plate on the ser-
vo amplifier using a cable tie.
Alternatively you can use the shielded
connection terminals (3) (available as
an accessory). These hook into the
bottom shielding plate and guarantee
optimum contact between the shield
and the shielding plate.
