(1) Single and two in parallel available with IP21 Rittal (catalog code A) and IP20 2500 MCC (catalog code P or W) enclosures. More than two units in parallel are only available with IP21 Rittal (catalog
code A) enclosures.
(2) <n> In catalog number is enclosure type; catalog code 3= IP21, catalog code 4= IP54.
(3) These ratings have lower maximum external DC bus capacitance specifications than the equivalent PowerFlex 700AFE. Review and determine the external DC bus capacitance (sum of all DC input
common bus inverter bus capacitance and connected capacitor banks) on the existing DC bus. If the existing total external DC bus capacitance is greater than the maximum for the selected PowerFlex
755TM bus supply, it may be necessary to select a larger rating for the PowerFlex 755TM bus supply. Maximum external DC bus capacitance specifications for the PowerFlex 755TM bus supply can be
found in Appendix A of the Drives in Common Bus Configurations with PowerFlex 755TM Bus Supplies application technique, publication DRIVES-AT005.
