Measure the resistance between the red or white coupler leading from the stator and the core.
If there is a section where insulation resist- ance is below 1MQ replace the part because it may cause insulation failure or such accidents as electric shock or leakage.
Measure the insulation resistance between either one of two slip rings of the rotor and the core.
If there is a section where insulation resist- ance is below lMS2,replace the part because it may cause insulation failure or such accidents as electric shock or leakage.
7-4-4 CONTROL PANEL
Measure the insulation resistance between the charging section (a part where electric current flows) and the grounded part.
If there is a section where insulation resist- ance is below lMS2,replace the part because it may cause insulation failure, or such accidents as electric shock or leakage.
