3 Hardware Description
3.7 Power Supply
The NetCom Plus devices are powered by a single 9-54V power supply. It requires 70 mA up to
750 mA of current, depending on the device type and voltage supplied. Connect the cable to the
Terminal Block at the rear side of NetCom Plus.
The NetCom Plus 411 / 811 POE devices are either powered by a single 15-54V power supply, in
the same way as the NetCom Plus and NetCom Plus with WLAN option devices; this also applies
to the NetCom Plus 811 DIO. The NetCom Plus 413 / 813 POE devices use the standard 9-54V
supply.
Or the NetCom Plus POE devices are powered via the network cable, connected to an Ethernet
switch with PoE function as IEEE 802.3af. This switch is referenced as the PSE (Power Sourcing
Equipment), while the NetCom Plus POE is the PD (Powered Device). It indicates itself as a
Class 0 device when sourced by the PSE. An external power adapter has priority over the PoE
function.
3.7.1 Terminal Block Power
The Terminal Block power connector receives positive volt-
age on the right (V+) pin. The center (V-) pin receives
ground voltage, and Field GND (FG) connects to the case.
Connect FG to Protective Earth Rail.
In NetCom Plus and NetCom Plus with WLAN option de-
vices the V- connects to the case.
V- is isolated in the
NetCom Plus 411 / 811 POE and NetCom Plus 811 DIO
devices.
