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.
When wiring the data lines, please refer to the description of the "FRIGOENTRY bus system".
We recommend the use of shielded cables for sensor extension.
