Mechanical protective measures are intended to protect PROFIBUS cables against breakage or a short circuit of the cores or mechanical damage of sheath and shield.
The measures for mechanical safety described here apply to electrical and optical cables alike!
Route the PROFIBUS cable in a protective plastic pipe if you route the PROFIBUS cable away from cable racks
In areas with heavy mechanical stresses, route the PROFIBUS cables in high-strength metal conduits. Hard PVC conduits may be used in areas with lower mechanical stresses.
In case of 90° bends and building joints (e.g. expansion joints), the protective pipe may be interrupted. It must be ensured that the PROFIBUS cable cannot be damaged, e.g. by falling objects.
In areas where people may step or vehicles pass, route the PROFIBUS cables in high-strength conduits or metal cable trays
Additional information about routing PROFIBUS cables outside of buildings, particularly in the ground, can be found in Chapter 1.1.
