Caution!
Before switching to the commercial power, make sure that, when the motor takes power directly from
the commercial power, it rotates in the forward direction as defined for operation by the inverter.
Do not set the Reverse-run prohibition parameter at or that forward run may be
prohibited. These settings make it impossible to switch the inverter to the forward run position,
and thus to switch from the inverter to the commercial power.
