Chapter 7 MAINTENANCE AND INSPECTION
Perform daily and periodic inspection to avoid trouble and keep reliable operation of the
inverter for a long time. When performing inspections, follow the instructions given in this
chapter.
• Before proceeding to the maintenance and inspection, turn OFF the power and wait at
least five minutes. Make sure that the LED monitor is turned OFF.
Electric shock may occur.
• Maintenance, inspection, and parts replacement should be made only by authorized persons.
• Take off the watch, rings and other metallic objects before starting work.
• Use insulated tools.
• Never modify the inverter.
Electric shock or injuries could occur.

7.1 Daily Inspection

Visually inspect the inverter for operation errors from the outside without removing the covers
when the inverter is ON or operating.
- Check that the expected performance (satisfying the standard specifications) is obtained.
- Check that the surrounding environment satisfies the requirements given in Chapter 2, Section
2.1 "Operating Environment."
- Check that the LED monitor on the keypad displays normally.
- Check for abnormal noise, odor, or excessive vibration.

7.2 Periodic Inspection

Perform periodic inspection according to the items listed in Table 7.1. Before performing
periodic inspection, be sure to stop the motor, shut down the power to the inverter, and then
remove the terminal block covers.
