2.6.4 Supply voltage with characteristic value PP
You will find information on the characteristic values here:
“Device name and product code” on page 17
You have the option of supplying the supply voltage redundantly, without
load distribution.
Both supply voltage inputs are uncoupled.
Ensure that the external power supply unit you use to provide the PoE
voltage fulfills the insulation requirements according to IEEE 802.3
(insulation resistance 48 V, output to the “rest of the world” 750 V DC for
60 seconds).

screw locking
For every supply voltage to be connected, perform the following steps:

Remove the power connector from the device.

Connect the wires according to the pin assignment on the device with the
clamps.

Fasten the wires connected by tightening the terminal screws.
