2) Insulation test in the control circuit
The megger test and the dielectric strength test
must not be executed in the control circuit be-
cause those parts will be damaged and cannot
be repaired.
Use a high-resistance multimeter for the control
circuit.
1. Remove all external wiring from the control
circuit terminals.
2. Execute a continuity test between
grounds. If the result is 1M
Ω
or more, it is
normal.
3) External main circuit and sequence control
circuit
Remove wiring from all the terminals of the in-
verter in order not to apply the test voltage to
the inverter.
