9.3.3 IPM Continuity Check
First turn off the power to the unit and wait approximately 20 seconds to allow the
electrolytic capacitors to fully discharge. Next remove the IPM from the PCB. Use a
multimeter to measure the resistance between P & UVWN; UVW & N. See the table below
for proper resistance values.
