Note: Relevant for BAT-Rail types:
The tightening torque for field wiring terminals is 2 - 4 lb in. (0.22 - 0.25 Nm).
2.11.3 Power over Ethernet (PoE) -
power supply via the LAN cable
The devices are powered devices complying with the PoE standard 802.3af.
You can therefore conveniently supply these devices with power via the LAN
cabling. This makes it unnecessary to have a separate power supply for
every individual device, thus considerably reducing the installation work.
In the BAT-F devices, the voltage is input via the wire pairs transmitting the
signal (IEEE 802.3af, mode A).
In the BAT-Rail devices it is also possible to supply the voltage via the free
wire pairs.
The power supply to the LAN is input centrally, or via a PoE injector or a
power hub/power switch.
Warning
In a PoE installation, only use devices that adhere to the 802.3af
standard! No warranty claims can be made for damage caused by
the use of impermissible devices.
