NOTICE
Cables not certified for the application can damage modules
Only use Siemens cables for the DRIVE-CLiQ connections.
Note
Protecting unused DRIVE-CLiQ interfaces
Close any unused DRIVE-CLiQ interfaces using the blanking covers provided.
Note
Equipotential bonding for distributed DRIVE-CLiQ nodes
Integrate all of the components that are connected via DRIVE-CLiQ into the equipotential
bonding concept. The connection should be preferably established by mounting on metallic
bare machine and plant components that are connected with one another using an
equipotential bonding conductor.
Alternatively, you can establish equipotential bonding using a conductor (min. 6 mm²), which as
far as possible, is routed in parallel to the DRIVE-CLiQ cable. This applies to all distributed
DRIVE-CLiQ nodes, such as DME20, SME2x, SME12x, etc.
If you have any further questions or are looking for particular solutions, you can contact the
Systems Engineering Plant Chemnitz directly.
