Maintenance and Inspection
WARNING
Do not touch the Inverter terminals while the power is being supplied.
WARNING
Maintenance or inspection must be performed only after turning OFF the power
supply, confirming that the CHARGE indicator (or status indicators) is turned OFF,
and after waiting for the time specified on the front cover. Not doing so may result in
electrical shock.
WARNING
Maintenance, inspection, or parts replacement must be performed by authorized
personnel. Not doing so may result in electrical shock or injury.
WARNING
Do not attempt to take the Unit apart or repair. Doing either of these may result in
electrical shock or injury.
Caution
Carefully handle the Inverter because it uses semiconductor elements. Careless
handling may result in malfunction.
Caution
Do not change wiring, disconnect connectors, the Operator, or optional items, or re-
place fans while power is being supplied. Doing so may result in injury, damage to
the product, or malfunction.
H
Daily Inspection
Check the following items with the system in operation.
•
The motor should not be vibrating or making unusual noises.
•
There should be no abnormal heat generation.
•
The output current value shown on the monitor display should not be higher than normal.
•
The cooling fan on the bottom of the Inverter should be operating normally, if the Inverter model has
the cooling fan.
H
Periodic Inspection
Check the following items during periodic maintenance.
Before beginning inspection, be sure to turn off the power supply. Confirm that all the indicators on the
front panel have turned off, and then wait until at least 1 minute has elapsed before beginning the in-
spection.
Be sure not to touch the terminals right after the power has been turned off. Otherwise, an electric shock
may occur.
•
The terminal screws of the Inverter should not loose.
•
There should be no conductive dust or oil mist on the terminal block or inside the Inverter.
•
The mounting screws of the Inverter should not be loose.
