• A direct voltage of up to 18 V must be used for the power
supply. The DC voltage must be located at the place of
installation (e.g. bell transformer or plug-in power supply
unit). When using a DC voltage, ensure that the cables are
connected in the correct polarity (observe the po and
negative/- signs).
Never connect a mains voltage here! Risk of fatal
electric shock!
• The "OPEN" and "COM" screw terminals can be used to
connect a door opener, which can be placed inside the room
next to the door. You can also connect additional buttons for
other door openers in parallel.
• Always connect the earth, as this prevents electrostatic
discharge (ESD) or interference that may cause the code lock
to malfunction.
• The diode should be connected as close as possible to the
N.O. contacts. This prevents a current from being generated
in the N.O contact coil due to mutual induction, which may
damage the code lock.
• Place the code lock on the lower section when you have
finished with the connections. Ensure that the cables are not
squashed, and check that they have not become detached
from the screw terminals.
• If necessary, use cable ties to fasten and organize the cables.
• Turn on the power supply. The red LED indicator (standby) will
turn on.
