1. Every device in the system bus must have a good PE connection.
2. Control cabinets, which include bus devices should be interconnected by a separate
equipotential bonding cable.
3. Motor cables should be screened; connect the screen to both ends:
–atthemotor
– at the controller.
Attach the screen using the supplied clamps to the screen sheet or to the conducting
mounting plate of the control cabinet. This means that the cable is stripped in the contact
area of the clamp thus providing a large-surface contact to the clamp and to PE.
4. Select system bus cables according to the specification in the Tab. 3-1.
– Connect the screen at both ends.
– Attach using the supplied screen plate:
K35.0021
Strip cable in the contact area of the clamp and make a large-surface contact to the clamp
and to PE.
5. Connect terminating resistor R
A
= 120Ω at the physical bus ends.
6. Separate control and fieldbus cables from the motor cable!
7. The CAN-GND cable must also be separated from the motor cable.
8. Connect terminal 7 with the screen plate of the controller.
9. Avoid stubs
