Electrical Connections
Made to Each Configured
Bay During Installation
This section provides a summary of the electrical connections that must be
made to each configured bay during installation, including connections to
other bays and connections to customer power source and motor. Make the
connections in this section as described in PowerFlex 755T Drives Configured
to Order Program Installation Instructions, publication 750-IN118
. This
section does not include all grounding connections. For grounding
connections, see Grounding Requirements on page 94
.
