Added instructions for drive installations in an ungrounded or high-impedance neutral ground or
systems
Updated the Typical Power Wiring Diagrams and the Field Converter Connections section to include
the step-down transformer required in the field converter input power supply circuit for 575V and
690V AC input drives.
and
Updated the Field Converter Connections section to include information on a requirements for a
step down transformer.
Updated the description for Par 469 [Field Mode Sel] option 1 “Field Weaken” to include the
