STR HT40 BUS System Nuki Opener Problems

Good Day Everyone,
I just received a new STR HT40 System as my old one broke a couple of days ago.
Now I am having trouble connecting it to the existing system. I read trough a couple of posts and of course asked AI but still not sure what to do.

Attached you may find a photo of the HT40s interior. Does anybody know what to do?

Thank you and Best Regards
