Wiring Your 8720MC

The following sections provide information and procedures on how to
wire your 8720MC. These procedures assume you have mounted your
8720MC components, bonded them to the subpanel, and have no
power applied to the system.

Power Wiring Requirements

Power wiring requirements are given in the tables below. Wire should
be copper with 75

° C (167° F) minimum rating. Phasing of main AC

power is arbitrary and earth ground connection is required for safe
and proper operation. Input drive power is either AC or DC
depending on your drive type and application. For additional
information refer to Power Specifications in Appendix A. Refer to
Appendix B for the 8720MC interconnect diagrams.
