Do not plug the power supply unit into the
NOT IC E
wall socket yet. Only use the power supply
unit provided along with the device, or a
DIN-rail power supply unit that you can obtain
from us separately, since this has been
specially stabilized electrically and is
equipped with an integrated audio inter-
ference reduction device. Other power
supply units may destroy the device or
cause poor transmission quality.
The warranty expires automatically if you
use a different power supply unit.
OPTION 2:
POWER SUPPLY AND NETWORK
CONNECTION USING POE (POWER OVER
ETHERNET)
To power the device via a PoE-Switch (e.g. D-Link
DGS-1008P) or PoE-Injector (e.g. DoorBird Gigabit PoE
Injector A1091) in accordance with the PoE standard
IEEE 802.3af Mode A, the four wires bearing the
numbers 1, 2, 3 and 6 of a Cat.5 cable or better are
to be used. A Cat.5 cable or better must be used
as network signals can only be transmitted over
completely insulated, shielded and twisted cables.
If you use PoE as a source of power the four wires for
PoE then simultaneously form the data link.
The device won't start if your PoE-Switch/PoE-Injector
does not support the PoE Standard IEEE 802.3af
Mode A (see Diagnostic-LED and Diagnostic-Sounds).
1. Disconnect the PoE-Switch or PoE-Injector
from the power grid.
2. Run the network cable to the installation
location of the device.

at the end of the wires that you would like to connect
to the green screw connection terminal of the device.
Please take care when connecting the cables
NOTI CE
and wires. Connecting the cables and wires
the wrong way may damage the device.
Wires without insolation material must not
protrude out of the green screw connection
terminal, it may lead to electrical short and
damage the device.
The yellow, green, and red cables that lead
NOTI CE
out from the side of the Main Electrical Unit
must only be used to connect components
certified by Bird Home Automation.
Handle the front plate with care. The surface
of the front plate could be scratched or
otherwise damaged if handled without care.
You can use the nylon
