Ipm On Transistor Pcb - Fujitsu ADUH09LUAS1 Service Manual

4-6. IPM on transistor PCB

Check point 1
1 Disconnect the connection wires between the transistor PCB—capacitor
PCB and transistor PCB—inverter PCB.
2 Set the tester to the resistance mode, and measure the resistance between the following termi-
nals.
TM301 (P)—TM305 (U)/TM304 (V)/TM303 (→)
TM302 (N)—TM305 (U)/TM304 (V)/TM303 (→)
3 Judge the result of 2 as follows:
