7-4-2 STATOR
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.
7-4-3 ROTOR
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.
