4.3.2 Design of the cables
ƒ
The cables used must comply with the approvals required for the location
(e.g. UL).
ƒ
It is imperative to comply with the regulations concerning minimum
cross-sections of PE conductors. The cross-section of the PE conductor
must be at least as large as the cross-section of the power connections.
ƒ
The effectiveness of a shielded cable is reached by:
–
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:
ƒ
Motor
ƒ
Motor holding brake (connected to optional motor brake control)
ƒ
Motor temperature monitoring
The following connections need not be shielded:
ƒ
DC bus
