1.5 Power supply
Solely for device variants featuring working voltage with the characteristic
value C, K or W:
For redundant and failure-resistant power supply, you have the option of
connecting multiple voltage sources in any combination at the same time.
The device selects the used voltage source automatically.
Switching to a redundant voltage source possibly occurs with a short delay.
If the voltage source currently active fails and another voltage source takes
over the supply of voltage to the device, the device reboots if necessary to
activate the redundant power supply.
1.5.1 Working voltage with the characteristic value C
A 4-pin 7/8" connector is available to supply the device.
You will find further information under “Working voltage with the
characteristic value C” on page 39 .
1.5.2 Working voltage with the characteristic value K
A 3-pin 7/8" connector is available to supply the device.
You will find further information under “Working voltage with the
characteristic value K” on page 40 .
1.5.3 Working voltage with the characteristic value P
Your device is a PD (powered device). PSE (power sourcing equipment)
connected via a twisted pair cable on the PoE PD port serves as the PoE
power supply voltage. The PoE power supply means that no separate power
supply is required for your device.
Note: With working voltage with the characteristic value P, the signal contact
is omitted.
You will find further information under “10/100/1000 Mbit/s PoE PD port” on
page 25 .
1.5.4 Working voltage with the characteristic value W
You have the following options to supply your device with voltage:

Power supply through a 7/8" connector
A 4-pin 7/8" connector is available to supply the device.
You will find further information under “Working voltage with the
characteristic value W” on page 41 .
