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 the data lines, we recommend using standard 2x2x0.8ø telephone cable with length up to
100m. The shielding must be grounded in the control cabinet. With cable lengths from 100m to 400m,
a shielded line with braided shield should be used.
For sensor extensions, it is recommended that sheathed cable be laid.
