4.2

Protective conductor connection and potential equalization

Requirement
You have mounted the Control Unit in the control cabinet.
The SIMOTION D4x5-2 Control Unit has a connection for the protective conductor and a
connection for the equipotential bonding conductor (M5 screw, Torx T25). Only one connection
is available for the CX32-2 - this must be used both for the protective conductor and the
equipotential bonding conductor.
Note
Requirements for functional safety for machines and systems; reliability and EMC are only
guaranteed with original SIEMENS cables.
Note the following safety information:
Danger to life from energized parts
Death or serious injury will result if energized parts are touched.
