  • Page 9: Mounting

    4 Mounting Mounting Mounting instructions VEGATOR 142 is designed for carrier rail mounting (top hat rail 35 x 7.5 according to DIN EN 50022/60715). Due to its protection rating of IP 20, the instrument is suitable for mounting in switching cabinets. It can be mounted horizontally and vertically.

  • Page 10: Connecting To Power Supply

    Detailed information about the power supply can be found in chapter "Technical data". Connection cable The voltage supply of VEGATOR 142 is connected with standard cable according to the national installation standards. The sensors are connected with standard two-wire cable without screen.

  • Page 11: Input Mode Active/Passive

    It is thus possible to control multiple controllers with one sensor to detect different limit levels. Note: With a VEGATOR 142 in Ex version, the passive input is not available for reasons of approval. Connection procedure The pluggable terminals can be removed as needed to allow more convenient connection.
