RS22/RS32 supply voltage
The RPS90/48V LV and RPS90/48V HV PoE power supply units provide
an output voltage of typically 48 V DC for supplying the RS22-.../RS32-...
devices with the PoE voltage.
Caution!
“Safety instructions” on page 4
and only connect a
supply voltage that corresponds to the type plate of your device.
Make sure that the contact load capability of the signal contact
is not exceeded
.
Connect the PoE voltage to the 6-pin terminal block for the device
included in the delivery.
Make sure the following requirements are met:
Supply line length < 0.5 m.

RS22/RS32 signal contact
The signal contact (“FAULT”, for pin assignment of terminal block, see
figure 16
) monitors the functioning of the device, thus enabling remote
diagnostics. You can specify the type of function monitoring in the
Management.
You can also use the graphical user interface of the switch to switch
the signal contact manually and thus control external devices.
