Connecting the PoE supply voltage to the M1-8TP-RJ45 PoE
media module (optional)
Warning:
Never insert sharp objects (small screwdrivers, wires,
etc.) into the terminal block for the supply voltage, and do not
touch the terminals! There is the risk of an electric shock.
Warning!
Use a fuse for the PoE supply voltage feed of the M1-8TP-
RJ45 PoE media module: 5 A slow blow.
Warning!
Disconnect the PoE voltage supply before removing the
M1-8TP-RJ45 PoE media module.
Warning!
Make sure that service personnel always have easy access to all
voltage supply connections of the basic device and the
M1-8TP-RJ45 PoE media module.
The PoE voltage is input via the wire pairs transmitting the signal
(phantom voltage).
The individual ports (joint PoE voltage) are not electrically insulated from
each other.
The following values apply to the PoE supply voltage of the module:
To supply the module with PoE voltage you need an external power
supply unit.
Make sure that the external power supply unit you use to provide the
PoE voltage fulfills the following basic prerequisites:
Insulation requirements according to IEEE 802.3af (insulation
resistance 48 V output to “rest of the world” 2250 V DC for 1 min.).
Output power < 250 W and sufficient to provide the power for the
connected PDs.
Current limitation < 5 A or fuse 5 A slow blow.
Rated voltage
48 V DC SELV
Minimum voltage
46 V DC
Maximum voltage
57 V DC
