(1) Wiring diagram for products without a noise suppressor
(2) Wiring diagram for products with a noise suppressor
Upon the completion of disassembly and repair, measure the insulation resistance and dielectric strength.
Insulation resistance: 7 Mȍ or more using a 500 VDC megohm tester
Dielectric strength: 4,000 VAC/minute, with no abnormalities (220 to 240 V)
(110 V for U.K. products)
2,500 VAC/minute, with no abnormalities (110 to 127 V)
(Except for U.K. products)
After no-load operation for 30 minutes, the no-load current values should be as follows:
Voltage (V) 110 220 230 240
Current (A) max.
