Chapter 8 Maintenance and inspectionCarry out preventive maintenance in order to ensure trouble-free use of the inverter for a longperiod of time.Carry out periodical inspection once every three to six months, depending on the operatingconditions. Before starting inspection, be sure to turn off the power switch（MCCB）and make surethat the CHARGE lamp is off.（Wait for at least ten minutes.）

8-1 Inspection points

１． Check if any wire terminal screws are loose. If loose screws are found, tighten them with a screwdriver.２．Check visually if any terminals are improperly crimped or have traces of overheat.３．Check the wires and cables visually for damage.４． Remove dust with an electric vacuum cleaner. Clean the vent holes and PCBs with great care. Dust or foreign matter may cause unexpected defects or troubles.５． If the inverter is not used for a long time, supply power once every two years and check that it

works properly. Disconnect the motor and supply electric power for at least five hours. Commercial electric power should be supplied to the inverter via a V ariac, etc. and the voltage

should be increased gradually. Power should not be applied directly to the inverter.６． If an insulation test is needed, conduct it on the main circuit terminal block only using a 500 V

megger. Never use any other terminals or the control circuit terminal of a PCB for aninsulation test. If an insulation test of the motor needs to be performed.

Disconnect the wires from the output terminals U, V and W, and perform an insulation test of themotor alone.

７． Do not carry out a Hi-pot test, which could break the internal parts. Carry out inspectionperiodically and ensure that a good environments is maintained.

８． Checking voltage and temperature. The input voltage and output voltage should be measured frequently using a tester to detect failures.

Record the readings daily, taking account of the characteristics of the tester or voltmeter used. 〔Recommended voltmeter〕 Input ：Moving iron type voltmeter（　　　　）　　　　　　　　　 Output：Rectifying voltmeter（　　　　） To detect failures more easily, the ambient temperature around the inverter should be measured

frequently when starting operation, during operation and when the machine is stopped.

-49-

8-2 Consumables

The inverter contains many semiconductors and electronic parts. The performance of the parts

shown below will deteriorate over time, resulting in deterioration of the inverter or failures.

Therefore, the inverter should be inspected for preventive maintenance.

（１） Smoothing capacitors

Ripple currents, etc., affect the aluminum electrolytic smoothing capacitors in the DC section of the

main circuit and the capacitor performances will be degraded. The degree of such

deterioration greatly depends on the ambient temperature and usage conditions. The

capacitors need to be replaced about every five years if the inverter is used under normal

environmental conditions.

Appearance Inspection Criteria

（a） Whether electrolyte leaks？

（b） Whether the safety valve is protruding or the capacitor has expanded？

（２） Cooling fan

The service life of the cooling fan for cooling the parts that generate heat is approximately 15,000

hours（or approximately two years if the inverter is run continuously）. If the fan generates

abnormal noise or vibration, it should be replaced.

-50-

8-3 Storage

If the inverter is not used after purchase but is to be stored temporarily or for a long time, follow the

instructions below：

１． Do not store the inverter in a hot or humid place exposed to vibration or metallic powder. Store

it in a well ventilated place.

２． If the inverter is not be used for a long period of time, supply power to it once every two years

to restore the characteristics of the smoothing capacitors. Check the functions of the inverter at

the same time.

Commercial electric power should be supplied to the inverter via a Variac, etc., and the voltage

should be increased gradually.

Power should not be supplied directly to the inverter.（Power should be supplied for at least five

hours）.

If the inverter is left turned off for a long period of time. the characteristics of the smoothing

capacitors in the inverter will deteriorate.
