as much as possible under general condition. If the test is unavoidable, please perform the test strictly
according to the following procedures, or it may damage the inverter.
It shall perform dielectric test strictly, or it may damage the inverter. If the dielectric test is unavoidable,
please contact our company.
Main Circuit Insulation Test
Utilize 500VDC megameter to perform test under condition of main power shutdown;
Disconnect all the control board circuits to prevent the control circuits from connecting with the
test voltage. For the inverter with power level of G-4011/P-4015 and G-4015/P-4018, it must
disconnect the terminal J1 on the drive board and the PE. For the inverter with power level of
G-4018/P-4022 or above, it must disconnect three pieces of cables entry to the surge absorption
circuit. Pack the disconnected cable heads with insulating tapes properly;
The main circuit terminal shall be connected with public conducting wires:

Fig.8-2 Main Circuit Insulation Test for G-4018/P-4022G-4400/P-4450
Megameter voltage can only be imposed between the public conducting wire of the main circuit
and the PE terminal;
The normal indication value of the megameter is 200MΩ or above.
