10.3.3 Recommendation for the mounting of CDI cables with long
lengths in an interference-prone environment
General information
The CDI cable is a connection cable with RJ45 plug to connect the CDI interface
of the control cabinet PC to the remote operator display or the Y-repeater.
The mounting recommendations described in the following facilitate an opti-
mized signal transmission. In particular in case of great cable lengths and dis-
tances between the control cabinet PC and the remote operator display, ensure
that the cable is routed correctly and that the shield is connected correctly.
Cables routing
Observe the following when laying the cables:
Keep the maximum possible distance to interference-prone cables and lines
●
Limit parallel routing with other lines
●
Keep the maximum possible distance to sources of interference such as
●
drives and frequency converters
Mechanical protection against tensile load and compressive load on the ca-
