For
every
supply voltage to be connected, perform the following work
steps:
Remove the terminal block from the device.
Connect the wires according to the pin assignment on the device with
the clamps.
Fasten the wires in the terminal block by tightening the terminal
screws.
You find the prescribed tightening torque in chapter:
“General technical data” on page 61
6.6.2
Supply voltage characteristic value L
Exclusively supply your device with SELV/ES1 voltage.
You will find information on the characteristic values here:
“Device name and product code” on page 21
You have the option of supplying the supply voltage redundantly, with load
distribution.
Both supply voltage inputs are electrically isolated.
