General

EMC requirements can be found in EN 60439-1 and recommendations in EN 60204-1. For
installation of components in cabinets, the following conditions must be ensured to comply
with the EMC Directive:
● Operation in TN systems with SINAMICS line filters
● Observance of information about cable shielding and equipotential bonding
● Use of recommended Siemens power and signal cables.
● Only Siemens cables may be used for DRIVE-CLiQ connections.
For MOTION-CONNECT cables see catalog D21.1.
CAUTION
For DRIVE-CLiQ connections it is not permissible to use cables and couplings (connectors)
that you have configured yourself.
14.5.2

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.

DANGER
A suitable PE conductor must be connected to all devices in protection class I.
