9-7. Insulation Tests
On completion of reassembly after repair, measure the insulation resistance and dielectric strength.
Insulation resistance: 7 M
Ω
or more with DC 500 V megohm tester
Dielectric strength : AC 4,000 V/1 minute, with no abnormalities ... 230 V (and 110 V for U.K. products)
AC 2,500 V/1 minute, with no abnormalities ... 110 V (except U.K. products)
9-8. No-load Current Values
After no-load operation for 30 minutes, the no-load current value should be as follows:
Voltage (V)
Current (A) Max.

9-6. Wiring of Variable Speed Control Switch
Insert each cord into the terminal 1 and terminal 2 of the speed control switch as shown in Fig. 31 and tighten
the screw [tightening torque: 0.6 0.2 N
•
m (6 2 kg
•
cm, 5.2 1.7 in-lbs.)]. Insert each lead wire (black) coming
from the stator ass'y into the terminals M1 and M2. Insert each lead wire (black) coming from the noise
suppressor into the terminals C1 and C2. After insertion, pull each lead wire slightly to check the lead wires do
not come off. To disconnect the lead wires, insert a small flatblade screwdriver into the slots near the terminals
and pull out the lead wires.
