Connection for an electronic door opener:
Connect the electronic door opener to RELAY 1, using either a separate power supply unit (version A) or
directly (version B) via the power supply of the video door station.
For version B, take note of the permitted power supply for your door opener:

A voltage that is too high can damage your door opener.

If the power consumption is too high for the switching procedure, the network supply
for your video door station can fail. Ensure that the power supply unit for your video
door station has a sufficient rating (min. 1A or higher).
