A door opener (E) can be connected directly, since the outdoor unit provides the operating voltage right at the two
connection terminals “D/O“.
The connection terminals “GATE“, in contrast, are potential-free. If another door opener is to be connected, e.g. for an
entrance gate (D) to the property, you need to provide the operating voltage with an external mains unit.
Always observe the contact resilience of the relay for the connection terminals “GATE” in the outdoor unit
(see chapter “Technical Data“).
Never switch the mains voltage via the connection terminals “GATE“! There is danger to life from electric
shock!
