8. Maintenance and Inspection

Proceed with daily inspection and periodic inspection to prevent malfunction and ensure long-term reliability. Note the following:

8-1 Daily Inspection

During operation, a visual inspection for abnormal operation is completed externally without removing the covers

The inspections usually cover the following:

(1)The performance (satisfying the standard specification) is as expected.

(2)The environment satisfies standard specifications.

(3)The keypad panel display is normal.

(4)There are no abnormal sounds, vibrations, or odors.

(5)There are no indications of overheating or no discoloration.

8-2 Periodical Inspection

Periodic inspections must be completed after stopping operations, cutting off the power source, and removing the surface cover.

Note that after turning off the power, the smoothing capacitors in the DC section in the main circuit take time to discharge. To prevent electric shock, confirm using a multimeter that the voltage has dropped below the safety value (25 V DC or below) after the charge lamp (CRG) goes off.

		• Start the inspection at least five minutes after turning off the power supply for
			inverter rated at 30HP or less, and ten minutes for inverter rated at 40HP or
			more. (Check that the charge lamp (CRG) goes off, and that the voltage is 25V
			DC or less between terminals P(+) and N(-). Electric shock may result.
！	WARNING	•	Only authorized personnel should perform maintenance and component
			replacement operations. (Remove metal jewelry such as watches and rings.)
			(Use insulated tools.))
		•	Never modify the inverter.
			Electric shock or injury may result.
