Upon completing disassembly and repair, measure the insulation resistance and conduct a dielectric
strength test.
Insulation resistance: 10M
:
or more using a DC 500 V megohm tester
Dielectric strength test: 4,400 VAC/3 sec., with no abnormalities ------------ More than 150 V of rated voltage
3,000 VAC/3 sec., with no abnormalities ------------ Less than 150 V of rated voltage
After no-load operation for 30 minutes, the no-load current values should be as follows.
