10. MAINTENANCE AND INSPECTION

WARNING

Be sure to turn off the power supply during maintenance and inspection.

After the power supply has been turned off, you must always wait 10 minutes so that DC bus
capacitors can discharge then start maintenance and inspection after the CHARGE lamp on the
printed-circuit board has gone out. (Immediately after the lamp has gone out, there will be a
residual voltage of about 50V DC in the DC bus intermediate circuit.)
Perform the work after the CHARGE lamp has stopped flickering.

Make sure that only qualified persons will perform maintenance, inspection and part replacement.
(Before starting the work, remove metallic objects from your person (wristwatch, bracelet, etc.)
(Be sure to use tools protected with insulation.)
Otherwise, there is a danger of electric shock and/or injury.

CAUTION

When removing connectors, never pull the wires. (Wires for cooling fan and thermal relay)
Otherwise, there is a danger of fire due to wire breakage and/or injury.

10.1 Maintenance and Inspection Precautions

10.2 Inspection Items

General precautions

Always keep the unit clean so that dust or other foreign matter does not enter the inverter.
Take special care in regard to breaking lines and connection mistakes. Firmly connect
terminals and connectors. Keep electronic equipment away from moisture and oil. Dust,
steel filing and other foreign matter can damage insulation, causing unexpected accidents,
so take special care.

(1) Daily inspection
(2) Periodic inspection (Approximately once a year)
(3) Insulation resistance tests, withstand voltage tests

See 10-3.
