1-6. Insulation Tests
Upon completing disassembly and repair, carefully measure the insulation resistance and
conduct a dielectric strength test.
Insulation resistance: 7 M
Ω
or more with 500 VDC megohm tester
Dielectric strength test: 4,000 VAC/1 minute with no abnormalities ----- 220 to 240 V products
2,500 VAC/1 minute with no abnormalities ----- 110 to 127 V products
1-7. No-load Current Value
After no-load running for 30 minutes, the no-load current value should be as follows:
Voltage
(V)
110 220 230 240
Current (A) max.
2.7
