Chapter 1
Installation and Wiring
This chapter provides information on how to mount and wire the PowerFlex DC
drive.
Most start-up difficulties are the result of incorrect wire connections. Take all
precautions to assure that wire connections are done as instructed. All items must
be read and understood before the actual installation begins.
For PowerFlex DC Stand-Alone Regulator (SAR) installations, see Appendix H
for important installation and configuration information. A 23PMDx catalog
number on the data nameplate on the drive identifies a SAR. (see Drive
Nameplate Data on page 12
for location).
