Release 01 11/2021
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
6.6.3
Signal contact
Connect the signal contact lines with the terminal block connections.
Fasten the wires in the terminal block by tightening the terminal screws.

Connecting data cables
Note the following general recommendations for data cable connections in
environments with high electrical interference levels:
Keep the length of the data cables as short as possible.
Use optical data cables for data transmission between buildings.
When using copper cables, provide sufficient separation between the
power supply cables and the data cables. Ideally, install the cables in
separate cable channels.
Verify that power supply cables and data cables do not run parallel over
longer distances. To reduce inductive coupling, verify that the power
supply cables and data cables cross at a 90° angle.
Use shielded data cables for gigabit transmission via copper cables, for
example SF/UTP cables according to ISO/IEC 11801. Exclusively use
shielded data cables to meet EMC requirements according to
EN 50121-4 and marine applications.
Connect the data cables according to your requirements.
See “Ethernet ports” on page 28.
