NICE Wingo (RJ MC424L R10) – how to connect a switch (video doorbell, door entry phone) to the gate motor

Any switch, video door entry system or GSM module can be connected to the NICE Wingo operator via a volt-free contact to inputs 8 and 12. 

If you need to connect additional devices to the operator that require an external 24V power supply, connect the device to terminals 6 and 7. The supplied voltage is 24Vdc -30% to +50%.
