Planning the Kinetix 2000 Drive System Installation
Observe the following guidelines when a LIM (2094-ALxxS, or
2094-XL75S-Cx) is used in a dc common bus configuration and the follower
IAM is mounted below the leader IAM:
• The very dirty zone (VD) is from the filter output to the Leader IAM,
and the entire length of the dc common bus cable. Shielded cable is
required on the EMC filter (load side) and the braided shield attached to
the clamp provided.
• Keep the dc common bus cable (very dirty) segregated from all other
cables (not in a wireway).
• The clean zone (C) is to the right and below the Kinetix 2000 system
(grey wireway).
• The dirty zone (D) is to the left of the Kinetix 2000 system, and above
and below the LIM (black wireway).
• The SERCOS fiber-optic cables are immune to electrical noise.
