Siemens SINUMERIK MCP-S Series - Power Supply; Ethernet Ports X20

• Using suitable cable clamps, connect the shield of the data line at the HMI device tightly to
a surface of the equipotential bonding rail.
• Route the equipotential-bonding cables and data cables parallel to each other and with a
minimum distance between them.
Note
Cable shields are not suitable for equipotential bonding. Only use the equipotential-bonding
cables required for this purpose. Ensure the cross-section of cables is su󹪟cient when setting
up PROFINET networks. Otherwise there is a risk that interface blocks can become damaged
or destroyed.
