On completion of reassembly after repair, measure the insulation resistance and conduct the dielectric
strength test.
Insulation resistance: 7 M
ȍ
or more with a 500 VDC megohm tester
Dielectric strength: 4,000 VAC/minute, with no abnormalities ······ 220 V to 240 V (110 V for UK products)
2,500 VAC/minute, with no abnormalities ······ 110 V to 127 V (except for UK products)
After no-load operation for 30 minutes, the no-load current values should be as follows:
Voltage
110 V
220 V
230 V
240 V
Current max.
3.8 A
1.8 A
1.7 A
1.7 A
