When wiring the PN/M-Bus LINK, follow the wiring guidelines of your automation system
(e.g. SIMATIC S7-1200, SIMATIC S7-1500, SIMATIC ET 200SP).
Also observe the installation instructions and configuration guidelines for routing of the
PROFINET cables.
Cable routing and grounding
Note
Electromagnetic interference
Ensure that all plants or systems in which PN/M
-Bus LINK is installed have sufficient
ntial bonding, for example, through a low impedance connection to the ground
Note
Strain relief
Ensure that all cables and leads that protrude externally are equipped with adequate strain
relief.
• The cables must be suitably dimensioned to ensure that they cannot be damaged. Make
sure that the cables are suitable for the individual application.
• Observe the bending radii.
For system for UL approval:
The cables must be specified for an ambient temperature of at least +75 °C.
