    Electrical connection Caution! For electrical installation, you are required to observe the relevant electrotechnical regulations of the country of use as well as the regulations of the local power suppliers. Make sure all electri- cal work is performed by trained and experienced personnel! Notes on installing the electrical connections Install the 230 V power supply lines and the signal lines separately! To increase noise immu- nity, observe a minimum distance of 10 cm between the lines.
  • Page 91 Connecting the sensors Cables with a minimum cross-section of 2 x 0.5 mm² can be connected to the terminals at the back panel of the housing. Connecting the actuators Connect cables with at least 1.5 mm² suitable for damp locations to the terminals of the control- ler output.
