Brief Check of POWER MODULE
If they are short-circuited, it means that they are broken.
Measure the resistance in the following points (connectors, etc.).
1. Check of DIODE MODULE
L1 - P1 , L2 - P1 , L3 - P1 , L1 - N1 , L2 - N1 , L3 - N1
2. Check of DIP-IPM
P2 - U , P2 - V , P2 - W , N2 - U , N2 - V , N2 - W
Note: The marks L1 , L2 , L3 , N1 , N2 , P1 , P2 , U , V and W
shown in the diagram are not actually printed on the board.
