(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.

Maximum DC Bus Capacitance (uF)
(2) (3)
(2) 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.
(3) 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
