•
*): Shielded cable, IY(ST)Y 0.8 mm or similar. Lay separately
from high-voltage cables.
•
**): Shielded paired cable e.g UNITRONIC® BUS LD 2x2x0.22
or similar. Lay separately from high-voltage cables.
•
All other connections can be done with NYM-J (or similar).
•
Wire cross-sections of unshielded cables are not specified, as
the length of the cable is involved in the calculation of the cross-
section.
•
Specifies the number of wires including protective conductor.
