Mounting, demounting and electric installation
10.7 Mounting recommendation for CDI+ cables with long
lengths in an interference-prone environment
The CDI+ cable is a connecting cable with an RJ45 plug to connect the CDI+ in-
terface of the control cabinet PC to the remote operator display or the
CDI+ splitter.
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.
10.7.1 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 load and compressive load on the ca-
●
bles
Comply with the permissible bending and torsional stress of the cable
●
Avoid dirt at the R45 plug which can occur while drawing in the cables in the
●
system.
10.7.2 Potential equalization
Ensure that no compensating current flows via the cable shield of the CDI+ ca-
bles between device and machine parts during the installation of the equipoten-
tial bonding.
10.7.3 Shielding
The shielding is an important component of the CDI+ cable. The shielding is
used to shield the data wires in the cable against electrical interferences from
the environment. The shielding has to be connected to the potential equalization
of the devices to shield the data wires. In most cases, a connection via the RJ45
connectors is sufficient.
Remove any collection of dirt from the shield surfaces of the RJ45 plugs before
plugging them in.
