Information
•
Pay attention to sufficient distance from powerlines and motor wires (min. 20 cm).
•
Except the data link "A (D+)", "B (D-)" and "GND"- connection may no further cable cores of the data
line be used.
•
Max allowed wire length 1000 m (CAT5/7 500 m).
Shielding
The use of shielded cables is normally not needed but offers high protection against electromagnetic
interferences, especially high frequencies. However, the effectiveness of the shield depends on care-
ful installation of the line.
If shielded cables are used, the shield should be placed at “PE” on at least one side (preferably on the
master connection). The occurrence of compensating currents may have to be considered if the shield
is contacted on both sides.
