13-5 Test Methods
When conducting megger test on the external circuit, remove all terminals of the inverter to avoid apply-
ing the test voltage is not applied to the inverter.
For energization test on the control circuit, use a tester (high-resistance range), and do not use a meg-
ger or buzzer.
Conduct megger test for the inverter itself only on the main circuit, and do not perform megger test on
the control circuit.
For megger test, use a 500 VDC megger.
Before conducting a megger test on the inverter main circuit, make sure to remove the short bar for
switching the filtering function included in the inverter, and short terminals R, S, T, U, V, W, P, PD, N,
RB, R0, and T0 as shown in the figure below.
After megger test, remove the wires on which R, S, T, U, V, W, P, PD, N, RB, R0, and T0 terminals that
are shorted, and connect the short bar for switching the filter function included in the inverter to the orig-
inal position.
Do not perform pressure test.
If pressure test is conducted, it is dangerous because the components inside the inverter may be dam-
aged or deteriorated.
