Unknown polarity of digital intercom systems

If you do not recognise the polarity of your system, there are two possible connection options:


  • Connection variant 1

    Remove the cable from BUS (1) and clamp it together with the yellow and red wire of the Opener in the extra connector block that came with your delivery.
    Then place the orange and green wire of the Opener in the connector of the system that has now become free.

    The cable in BUS (2) stays connected. The black wire of the Opener is simply clamped in here.
    If at the beginning of the configuration a message appears stating that the wiring is not correct, try connection variant 2.
