An EMC Compatible Assembly
To provide immunity to interference and thus ensure trouble-free operation, the
design and assembly of the PLC’s hardware must satisfy EMC considerations.
Furthermore, both it and the connecting cables must be properly shielded. The
installation guidelines for achieving interference-free operation of your PLC also
apply when installing the operator panel.
!
Caution
All signal links must use shielded wiring only.
All connectors must be secured by screws or catches.
Signal cables may not share a cable duct with power cables.
Siemens AG assumes no liability for malfunctions or damages that result from
cables assembled by the customer or made by other companies!
