4.2 Pin assignment

Wiring work must only be performed when the equipment is
disconnected from the power supply. The special VDE regulations and
the local installation regulations must be observed.

In doing so observe the maximum values for operating parameters
indicated on the wiring diagram.

Sensor connection

The sensor is connected to the terminals 1 (-) and 2 (+).
