5.8.1 General information
Danger
If the shielding procedures described and the specified cable lengths are not observed, the
machine may not operate properly.
5.8.2 Cable shielding and routing
In order to comply with the EMC requirements, certain cables must be routed apart from
other cables and from certain components. To full EMC requirements, the following cables
must be used with shields:
Power supply cables from line filter via line reactor to Line Module
All motor cables (if necessary, including cables for motor holding brake)
Cables for "fast inputs" of the Control Unit
Cables for analog direct voltage/current signals
Signal cables for sensors
Cables for temperature sensors
Alternative measures (e.g. routing behind mounting plates, suitable clearances) can also be
used provided they have similar results. This excludes measures that relate to the design,
installation, and routing of motor power cables and signal cables. If unshielded cables are
used between the line connection point and line filter, make sure that no interfering cables
are routed in parallel.
The cable shields must be connected as close to the conductor terminal connections as
possible to ensure a low-impedance connection with cabinet ground. For Siemens power
cables in which the shield is connected to the connector shell (see relevant catalog), this is a
sufficiently good shield contact.
With components that do not have any special shield connection or where the shield
connection is not sufficient, the cable shields can be connected to the metal mounting plate
using hose clamps and toothed rails. The cable length between the shield contact point and
the terminals for cable conductors must be kept as short as possible.
Shield contact plates with pre-prepared clip contacts are available for contacting the shields
for power cables of Line Modules and Motor Modules. Up to a module width of 100 mm,
these plates are part of the scope of supply of the components, or they are integrated in the
connector.
