Safety precautions in wiring work (See Fig. 22.)
Switch (B) [97] is flexibly supported by the Support [98] to protect it from damage from vibration which could
lead to possible electrical shock. Ensure without fail that the Support is properly mounted. Also, ensure that
the leadwires are properly covered by Vinyl Tube (A) [102], and that the leadwires of the Stator Ass'y [76] and
the grounding leadwire are properly supported by the Internal Wire Holder [80].
9-1-6. Insulation Tests
On completion of disassembly and repair, measure the insulation resistance and dielectric strength.
Insulation resistance: 7 M Ω or more with DC 500 V Megohm Tester
Dielectric strength: AC 4000 V/1 minute, with no abnormalities
AC 2500 V/1 minute, with no abnormalities
9-1-7. No-Load Current Value
After no-load operation for 30 minutes, the no-load current value should be as follows:
Voltage (V)
Current (A) max.
