2.6.3 Supply voltage with the characteristic value CC
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.
Figure 5: Supply voltage with the characteristic value CC: 2-pin terminal block with
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.
With a non-redundant supply of the supply voltage, the device reports the
loss of a supply voltage. You can prevent this message by applying the
supply voltage via both inputs, or by changing the configuration in the
Management.
