ƒ
Power supply modules, mains chokes or mains filters may be connected to the mains
via unshielded single cores or unshielded cables.
ƒ
Cables between mains filters/RFI filters and power supply modules:
– Install twisted and with sufficient distance to adjacent cables.
– If cables are routed together in a cable duct or if longer cable lengths are used, we
recommend the use of shielded cables, e.g. between two control cabinets.
ƒ
The integrated DC busbars (X101/102) do not require EMC measures.
ƒ
Installation of cables for DC supply:
– Up to a length of 300 mm, twisted unshielded cables can be used, e.g. between an
upper and a lower installation row.
– From a length of 300 mm onwards, we recommend the use of shielded cables, e.g.
between two control cabinets.
ƒ
The cable cross−section must be dimensioned for the assigned fusing (observe
national and regional regulations).
