Measurements on the main circuit

This section describes the measurement of the main circuit voltages, currents, powers and in-
sulation resistance.

Please follow as well the instructions for measuring instruments and measuring methods in
section 7.7.

8.2.1

Insulation resistance test using megger

For the inverter, conduct the insulation resistance test on the main circuit only as shown below
and do not perform the test on the control circuit. (Use a 500V DC megger.)

8.2.2 Pressure

test

Do not conduct a pressure test. Deterioration may occur.

Fig. 8-7:

Insulation resistance test

b

CAUTION:

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.

NOTE

For the continuity test of the control circuit, use a tester (high resistance range) and do not
use the megger or buzzer.
