(1) Modules are available in single density and dual density. Modules can be paralleled to increase the rating. In this table ‘1X’ means one single-density module, ‘2X’ means one dual-density module. See
Paralleling PowerFlex 755TM Non-regenerative Modules on page 41 for more information.

(5) For paralleled modules, sum the corresponding 1X and 2X maximum external capacitance values to obtain the overall bus supply system maximum external DC bus capacitance value.
(6) Select the fastest precharge ramp time that supports the total connected DC bus capacitance. Perform calculations to determine the required DC bus capacitance and the system total DC bus
capacitance. See DC Bus Capacitance Calculation Method on page 87.
