Chapter 1
Installation and Wiring
This chapter provides information on mounting and wiring the PowerFlex DC
drive.
Most start-up difficulties are the result of incorrect wiring. Every precaution must
be taken to assure that the wiring is done as instructed. All items must be read and
understood before the actual installation begins.
For PowerFlex DC Standalone Regulator (SAR) installations, see Appendix H
for important installation and configuration information. The SAR is identified
by a 23PMDx catalog number contained on the data nameplate on the drive (see
Drive Nameplate Data on page 12
for location).
