Danger!
Observe all national and regional regulations for the cables.
You can use single and multi−core cables. If a cable consists of several cores
per phase, it can be necessary to connect the controller by means of common
cable glands.

1) Two conductors per path; both conductors must have the same cross−section
The effectively required cable cross−section depends e.g. on the application
and environmental conditions and the cable type used. It is not required that
mains and motor cable have the same cable cross−section.
It is not necessary to shield the mains cable. In DC−bus operation or with DC
supply we recommend shielded cables.
It is not necessary to fuse the motor cable. For EMC reasons we recommend
shielded motor cables. You can use common metal clamps to connect the
shield.
