PRECAUTIONS FOR MAINTENANCE AND INSPECTION

The converter unit is a static unit mainly consisting of semiconductor devices. Daily inspection must be performed to prevent
any fault from occurring due to the adverse effects of the operating environment, such as temperature, humidity, dust, dirt and
vibration, changes in the parts with time, service life, and other factors.



Precautions for maintenance and inspection

When accessing the converter unit for inspection, wait for at least 10 minutes after the power supply has been switched OFF
because the smoothing capacitor voltage remains high for a while, and then make sure that the voltage across the main circuit
terminals P/+ and N/- of the converter unit is not more than 30 VDC using a tester, etc.

7.1

Inspection item

7.1.1

Daily inspection

Basically, check for the following faults during operation.
• Motor operation fault
• Improper installation environment
• Cooling system fault
• Abnormal vibration, abnormal noise
• Abnormal overheat, discoloration

7.1.2

Periodic inspection

Check the areas inaccessible during operation and requiring periodic inspection.
Consult us for periodic inspection.
• Check and clean the cooling system. ............... Clean the air filter, etc.
• Check the tightening and retighten. .................. The screws and bolts may become loose due to vibration, temperature

changes, etc. Check and tighten them.
Tighten them according to the specified tightening torque. (Refer to

.)

• Check the conductors and insulating materials for corrosion and damage.
• Measure the insulation resistance.
• Check and change the cooling fan and relay.
