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.
You find the prescribed tightening torque in chapter:
“General technical data” on page 61
6.7 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.
