8.3 System integration
Note
System compatibility is guaranteed only if shielded power cables are used and the shield is
conductively bonded over a large area to the metal motor terminal box (using metal EMC
cable gland) or by using a power connector.
Ground open or unused conductors - or electric cables that can be touched. Contact the
shields with ground potential over the greatest possible surface area. Connect the open-
circuit motor cables to the terminals provided for this purpose. Open-circuit cables carry
capacitive charges and can result in malfunctions.
Lead in permanently laid cables and conductors using EMC cable glands. The cable glands
are screwed into the threaded holes of the terminal box.
Close off unused threads with a metal threaded plug.
Pre-assembled cables offer many advantages over cables assembled by customers
themselves. In addition to having the security of knowing that they function perfectly and are
high quality products, there are also some associated cost benefits when using prefabricated
cables.
● Use the power and signal cables from the MOTION-CONNECT family.
● Observe the maximum cable lengths.
You can find information on the technical data of the cables in the Catalog, Chapter
"MOTION-CONNECT connection system".
Cable installation
Note
Avoiding disturbing effects
Route signal cables separately from power cables in order to avoid disturbing effects (e.g. as
a result of EMC).
