Fig. 3: Dimensions
For wiring of the data lines, we recommend the use of standard telephone lines 2x2x0.8ø. up to
lengths of 100m. The shielding must be grounded in the control cabinet. For cable lengths from 100m
to 400m, shielded lines with braided sheathing should be used.
Sensor extension
For sensor extensions, it is recommended that sheathed cable be laid.
