Table 1: Minimum spacing for cables (according to EN 50174) shows the distances according to EN 50174-2 that must be maintained between PROFIBUS cables (shielded data cable) and other cables. The table also lists two variants with a metal isolating segment. Here, it is assumed that a metal partition has the same effect as a cable shield.

How to read the table
To determine the minimum distance between PROFIBUS cables and other electrical cables, proceed as follows:
In the left column (PROFIBUS cable and cable for...) select which electrical cables you want to route together with the PROFIBUS cables.
In the right table section (spacing), select the type of cable separation to be used.
The spacing for the respective cable type routing can be found in the column with the respective type of cable separation.
In addition, observe the regulations for the different routing areas found below Table 1.
In general, the greater the spacing between the cables and the shorter the paths run parallel, the lower the risks of interference (crosstalk).
