10.6.4 Recommendation for the mounting of CDI cables with long
lengths in an interference-prone environment
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.
These mounting recommendations facilitate an optimized signal transmission. In
particular in case of great cable lengths and distances between the control cabi-
net PC and the remote operator display, ensure that the cable is installed cor-
rectly and that the shield is connected correctly.
Cables routing
Observe the following when routing 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 and compressive load on the cables
●
Comply with the permissible bending stress and torsional stress of the cable
●
Avoid collection of dirt at the R45 plug which can occur while drawing the ca-
●
bles into the system.
Potential equalization
Ensure that no compensating current flows via the cable shield of the CDI cables
between device and machine parts during the installation of the equipotential
bonding.
