HIPOT TESTING
Perform a second test between the output shaft and
the wiring at the same voltage as below (Figure 65).

Testing the Motor

If the tester signals a failure, it will be necessary to
disassemble the unit and inspect the electric
components that are near the area where the tester
signaled a failure. (For example, if you probed a screw
when the tester indicated failure, look for insulation
damage near that screw.) Repair the damaged
insulation and reassemble the unit.
If in the process of repair of product you expose the
motor, it is a good idea to test the motor itself. The
motor should have internal insulation to prevent
voltage from reaching the case or output shaft.
Set the tester to the desired voltage and test between
the motor case and the two wires that normally supply
power to the motor (Figure 64). The tester should NOT
signal a failure. If the tester does signal a failure, the
internal insulation has failed and the motor will fail
soon.
Retest to insure your repair was effective.
Make a note on the work order that the product was
hipot tested and at what voltage.
