Fermax 5613

Hi, Can anyone advise me how to connect the Nuki Opener to a Fermax 5613 intercom as shown in the attached photo? The wiring configuration for the Fermax 5613 appears to be as follows:

  • A T
  • 1 2 3 4 6 Ct + - V
  • M V
  • F1 F2

It would be really appreciated. Thank you for your help in advance.
