To connect supply voltage, perform the following steps:
Ensure the required conditions for connecting the supply voltage are
observed (see page 5 “Supply voltage”).
Remove the power connector from the device.
Connect the protective conductor to the protective conductor terminal.
Connect the lines for the supply voltage to the terminals +/L and −/N.
Operating voltage type CC
You have the option to supply the supply voltage redundantly, with no
load distribution.
Both inputs are separate from one another.
