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 ele-
ments. Careless handling may result in malfunction.

Caution

Do not change wiring, disconnect connectors or Operator, or re-
place fans while power is being supplied. Doing so may result in inju-
ry 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 nor-
mal.

•

The cooling fan on the bottom of the Inverter should be operating normally, if the Invert-
er model has the cooling fan.
