Drive Installation Chapter 2
The wire sizes must be selected individually, observing all applicable safety and
CEC, IEC or NEC regulations. The minimum permissible wire size does not
necessarily result in the best operating economy. The minimum recommended
size for the wires between the drive and the motor is the same as that used with an
across-the-line starter. The distance between the drive and motor may affect the
size of the conductors used.
Consult the wiring diagrams and appropriate CEC, IEC or NEC regulations to
determine correct power wiring. If assistance is needed, contact your local
Rockwell Automation Sales Office.
Power Cabling Access The drive is built with provision for either the top or bottom power cable entry.
Cable access plates are provided on the top and bottom plates of the connection
cabinet identified by the customer specific dimension drawing (DD).
Access the Customer Power Cable Terminations
Cable connections are located behind the medium voltage door of the
Connection/Cabling cabinet. Location of power terminals for various drive
configurations are as indicated in
Figure 30 through Figure 33 .
In the case of the cabling cabinet with starter, the removal of internal barriers and
duct covers located on the left side of the cabinet may be required to facilitate the
routing of line cables. This can be accomplished by removing the hardware
securing the barrier/cover and sliding it toward the front of the cabinet for
removal. In addition the fan housing and cover plate (if already installed) located
on the top of the cabinet must be removed to allow routing and termination of
line cables. All barriers/covers must be replaced, by reversing the above sequence,
before applying medium voltage.
The installer is responsible for modifying the power cable access plates to suit
their requirements.
Note that appropriate connectors must be used to maintain the environmental
rating of the enclosure.
