Important!
If the device is operated by a power supply (and possibly an additional UPS), batteries must not be in-
serted.
The outdoor unit has a potential-free switch contact (contact load capacity, see chapter "Technical data").
Therefore either a "fail-secure" or a "fail-safe" door opener can be connected. Never switch the mains volt-
age over the connection terminals of the outdoor unit! An electric shock poses a risk to life!
Wiring diagram for "Fail-Secure" door opener:
This releases the locking

Wiring diagram for "Fail-Safe" door opener:
It releases the locking latch only
when the operating voltage is absent (rare type, used, for example, for escape
route doors, as the door can be opened in the event of a power failure).
