Chapter 2 Install the Kinetix 7000 Drive System
When mounting your shunt module inside the enclosure, follow these additional
guidelines.
• Metal-clad modules can be mounted anywhere in the dirty zone, but as
close to the Kinetix 7000 system as possible.
• Shunt power wires can be run with motor power cables.
• Keep unshielded wiring as short as possible. Keep shunt wiring as flat to
the cabinet as possible.
• Separate shunt power cables from other sensitive, low voltage signal cables.
• The shunt module watts dissipation must be included in the Kinetix 7000
system heat dissipation calculation for selecting an enclosure.

Motor Brake and Thermal Switch
The thermal switch and brake are mounted inside the motor, but how you
connect to the axis module depends on the motor series.
See Wire Motor Output Power on page 92 for wiring guidelines specific to your
drive/motor combination, and to Interconnect Diagram Notes on page 162 for
the interconnect diagram of your drive/motor combination.
