9．MAINTENANCE AND CARE
As a result of ambient temperature, humidity, dust, vibration and aging of internal components of inverter,
the inverter will probably appear the potential problem during running. In order to ensure the inverter to run
steadily for a long time, the inverter should be checked up once at 3 to 6 months.
First of all, turn the inverter’s power off. And professional worker performs nance.
9.1 Daily Maintenance
The daily inspection and care can contribute to promptly discover different abnormal situations, find out the reasons for
abnormity, early eliminate hidden dangers of fault, ensure the equipment to normally run, and prolong the service life
of the converter. Please refer to the following table for the daily inspection and care

⑴Inverter has done the electric insulating experiment before leave-factory, so user don’t need to do the withstand
voltage test.
⑵Do the insulation test to the inverter if necessary, all of I/O terminals must be connected in short-circuit
(R, S, T,L1,L2, U, V, W, P, P-, PB). Strictly prohibit from doing the insulation test for the single terminal. Please use
500V Meg-ohmmeter to perform this test.
⑶Control circuit can not be used the Meg-ohmmeter to test.
⑷ For insulation test to motor, the connection wire between motor and inverter should be disassembled.
