Rockwell Automation Publication 20Y-TG002C-EN-P - April 2017
Chapter 6
Precharge Component Section
The precharge resistance is approximately 11 Ω for each measurement
for an AFE in an IP20 2500 MCC Style enclosure, or 20 Ω for each
measurement for an AFE in an IP21 Rittal enclosure. If the measured
value is not correct, disconnect a resistor wire and remeasure again. If the
measured value is still not correct, replace the precharge resistor.
IMPORTANT
Verify that the precharge resistor has not been engineered to
another value by the system engineer to accommodate a larger
system capacitance. The engineered value can change the value of
the precharge resistance. See the PowerFlex Active Front End User
Manual, publication
, for total DC bus capacitance limits
for the precharging circuit.
