Design of the cables

6.3.2 Design of the cables
The cables used must comply with the approvals required for the location (e.g. UL).
ƒ
The cross−section of the PE conductor must be dimensioned according to the
ƒ
relevant national regulations.
The effectiveness of a shielded cable is reached by:
ƒ
– Providing a good shield connection through large−surface shield contact.
– Using only braided shields with low shield resistance made of tin−plated or
nickel−plated copper braid.
– Using braided shields with an overlap rate > 70 % and an overlap angle of 90 °.
– Keeping unshielded cable ends as short as possible.
Use system cables or shielded cables for these connections:

The following connections need not be shielded:
Mains

24 V supply
ƒ
Digital signals (inputs and outputs)
