7.2.7 Insulation resistance test using megger
• For the inverter, conduct the insulation resistance test on the main circuit only as follows and do not perform the test on
the control circuit.
(Use a 500 VDC megger.)
NOTE
• Before performing the insulation resistance test on the external circuit, disconnect the cables from all terminals of the inverter
so that the test voltage is not applied to the inverter.
• For the continuity test of the control circuit, use a tester (high resistance range) and do not use the megger or buzzer.
7.2.8 Pressure test
Do not conduct a pressure test. Deterioration may occur.
