5-7. 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 (W)
TM302 (N)—TM305 (U)/TM304 (V)/TM303 (W)
3
Judge the result of 2 as follows:
