10% 50/60 Hz, Hz power supply input, which via fuse
F3 powers the primary of the toroidal transformer
- already wired -
Motor power supply 24Vdc output
Start control input (NO contact) controls the opening and closure
with inversion during movement.
Common input terminals
Input for the connection of the antenna for the built-in receiver. For
normal capacity, the calibrated wire already connected is sufficient.

20Vac-24Vdc input for power supply of the circuit board
supplied via a toroidal transformer- already wired-
Input for the connection of 2 12V 2Ah buffer batteries
(optionals, e.g. SERAI BT/20) to guarantee functioning of the
automation in the case of a power cut. In presence of the
circuit board network voltage, it recharges the batteries via the
built-in battery-charger.
Closure limit switch input (NC contact)
