Table 5 Checking the transistor modules and
diode modules
Normal conditidns Normal conditions
Notes: 1. Before measurement, check that the smoothing capacitor
have
been discharged.
2. “Discontinuity” means that the multimeter reading is almost
infinite. Due to electricity remaining in smqothing capacitor,
the multimeter may indicate “continuity” momentarily.
“Continuity” means that the multimeter reading is about
1 - lOOohm, depending on number of total modules, number
of modules connected in parallel, type of- modules, etc.
If all measurement results are almost same, the modules
are in good condition.
