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:
Motor
ƒ
Motor holding brake (shielding is required when being integrated into the motor
ƒ
cable; connection to optional motor brake control)
Motor temperature monitoring
ƒ
External brake resistor (, Mounting Instructions of the brake resistor)
ƒ
The following connections need not be shielded:
Mains
ƒ
DC bus, cable length up to 0.3 m
