AC and DC regardless of polarity. Make sure that the current and voltage values do
not exceed limits (refer to the Technical Data) and that the technical parameters of
the lock and power supply are compatible.
Warning
Never switch 230 or 120 V mains voltage directly!!!
Caution
If the lock power supply fails and the telephone system carries on
working, the intercom is unaware of the failure the switch will be
password-activated and the activation is acoustically signalled, but the
electric lock will not work because of the lack of power.
Ground connection is mandatory. If used power supply output is
grounded, you can connect GND terminal to it.
