The manufacturer specifies a maximum tensile strength for every cable type. Exceeding the maximum tensile strength damages or destroys the PROFIBUS cable. This is of particular importance in drag chains and garland suspensions due to the high mechanical load. Ensure that you choose the right type of cable for your application:
PROFIBUS standard cable
PROFIBUS trailing cablel
PROFIBUS festoon cable
Bitte beachten Sie im Umgang mit dem PROFIBUS-Kabel folgende Punkte:
Pull the PROFIBUS cable by hand only. Do not apply force when pulling.
Consider using rollers, for example, to provide strain relief when laying PROFIBUS cables.
Pulling PROFIBUS cables with cable grips, protecting connectors
Use cable grips for pulling PROFIBUS cables. If you have already assembled the PROFIBUS cable, you must protect the connector against mechanical load before attaching the cable grip. This can be achieved by placing a protective pipe over the connector.
Strain relief
Attach a strain relief to all cables that are subject to a tensile load at a distance of approximately 1 m from the connection point. The shield area at the cabinet entry is not sufficient for strain relief! Appropriate strain relief fittings are available from several manufacturers.
