Drive Installation
Chapter 2
The wire sizes must be selected individually, observing all applicable safety and
CEC or IEC / 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 if a
main voltage source connection to the motor was used. The distance between the
drive and motor may affect the size of the conductors used.
Consult the wiring diagrams and appropriate CEC or IEC / 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.
Access the Customer Power Cable Terminations:
•
Open the door of the low voltage control compartment. The low voltage
control compartment is hinged on its left side. The power terminals are
behind the low voltage control compartment.
•
Note that there is a key interlock to prevent swinging the low voltage
control compartment open unless the medium voltage source is locked
out.
•
Turn each of the three latches on the right side of the low voltage
compartment one-quarter turn using an 8-mm hexagonal key wrench.
There is a pull handle provided on the right side of the low voltage
compartment.
•
Slowly pull the handle so that the low voltage compartment swings out.
The power terminals are now visible.
•
The installer is responsible for modifying the power cable access plates to
suit the requirements.
•
Note that appropriate connectors must be used to maintain the
environmental rating of the enclosure.
