Place the device with the upper guide edge
on the top-hat rail.
Then press the device gently downward until
it engages with the fastening safety catch on
the top-hat rail.
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.
We recommend the use of shielded cables for sensor extension.
