10. CONFIRMATION AFTER REASSEMBLY

10-1. Lead Wire Precautions

When connecting lead wires, be very careful not to remove the insulation covering of each lead wire more than
needed. Also, ensure that the lead wires are not pinched between the mating surfaces of the handle.

10-2. Insulation Tests

On completion of disassembly and repair, measure the insulation resistatance and conduct dielectric strength test.
Insulation resistance: 7 MΩ or more with DC 500 V Megohm Tester
Dielectric strength: AC 4000 V/1 minute, with no abnormalities ... 220 V to 240 V
AC 2500 V/1 minute, with no abnormalities ... 110 V to 127 V

10-3. No-Load Current Value

After no-load operation for 30 minutes, the no-load current value should be as specified below at a frequency of
50/60 Hz.
110 V ... 4.4 A max.
127 V ... 4.3 A max.
240 V ... 2.1 A max.
115 V ... 4.2 A max.
220 V ... 2.1 A max.
--- 25 ---
120 V ... 4.1 A max.
230 V ... 2.2 A max.
