Maintenance Operations
■ Operation and Maintenance
• Take measures to assure safety before performing maintenance or inspection, or replacing compo-
nents.
■ Operation Command Selection
• If the operation command selection parameter (P10) is set to “PLC” to enable using the control cir-
cuit terminal inputs (STF and STR), the motor may start operation when the power supply is turned
ON or an alarm is reset if the control circuit terminals are left ON. Exercise suitable caution. Also, if
signals are checked during operation and a voltage is incorrectly applied to the control circuit termi-
nals, the motor may start moving unexpectedly. Always check safety before performing signal
checks.
■
Disposing of the Inverter
• Observe all applicable legal requirements when disposing of the Inverter.
Caution
Do not touch the Inverter terminals while the power is being supplied or for at least
one minute after the power has been turned OFF.
Doing so may occasionally result in minor injury from electrical shock.
Do not remove the fan cover except when replacing the fan. Before replacing the fan,
first turn OFF the power and disconnect the wiring.
Doing so may occasionally result in minor injury from electrical shock.
