Installing the Device
2.5.3 Connecting External PoE Power
Note
For IEC 61850 compliance, use an IEC 61850 compliant PoE power supply with pow-
er cabling no longer than 3 m (118 in).
Otherwise, Siemens recommends using the RUGGEDCOM RPS1300 switch-mode AC
power supply. For more information about this power supply, refer to
port.industry.siemens.com/cs/ww/en/view/109478699
To support the
IEEE 802.3at
specification (60 W/port output), the external power
supply must meet the following requirements:
Input Range
Power Sup-
ply Type
Minimum
Maximum
Isolation
Minimum Pow-
er Required
DC
51 VDC
57 VDC
1.5 kVAC/2.2 kVDC
150 W
Based on a single 4-port module.
To support the
IEEE 802.3af
specification (15 W/port output), the external power
supply must meet the following requirements:
Input Range
Power Sup-
ply Type
Minimum
Maximum
Isolation
Minimum Pow-
er Required
DC
45 VDC
57 VDC
1.5 kVAC/2.2 kVDC
72 W
Based on a single 4-port module.
To connect an external power supply for the PoE ports, do the following:
1. Secure a European-style terminal block (or Euroblock) to the terminal.

2. Connect the positive wire from the RUGGEDCOM RPS1300 (or another external
power supply) to the positive (+) terminal on the terminal block.
3. Connect the negative wire from the RUGGEDCOM RPS1300 (or another external
power supply) to the negative (-) terminal on the terminal block.
