WARNING: Be sure not to touch the inside of the energized inverter or to put any
conductive object into it. Otherwise, there is a danger of electric shock and/or fire.
… 4-3
WARNING: If power is turned ON when the Run command is already active, the
motor will automatically start and injury may result. Before turning ON the power,
confirm that the RUN command is not present.

… 4-3
WARNING: When the Stop key function is disabled, pressing the Stop key does not
stop the inverter, nor will it reset a trip alarm.
WARNING: Be sure to provide a separate, hard-wired emergency stop switch when
the application warrants it.
… 4-3
WARNING: If the power is turned ON and the Run command is already active, the
motor starts rotation and is dangerous! Before turning power ON, confirm that the
Run command is not active.
… 4-11
WARNING: After the Reset command is given and the alarm reset occurs, the
motor will restart suddenly if the Run command is already active. Be sure to set the
alarm reset after verifying that the Run command is OFF to prevent injury to
personnel.

Cautions for Operations and Monitoring
CAUTION: The heat sink fins will have a high temperature. Be careful not to touch
them. Otherwise, there is the danger of getting burned.
… 4-2
CAUTION: The operation of the inverter can be easily changed from low speed to
high speed. Be sure to check the capability and limitations of the motor and
machine before operating the inverter. Otherwise, it may cause injury to personnel.
… 4-2
CAUTION: If you operate a motor at a frequency higher than the inverter standard
default setting (50Hz/60Hz), be sure to check the motor and machine specifications
with the respective manufacturer. Only operate the motor at elevated frequencies
after getting their approval. Otherwise, there is the danger of equipment damage.
… 4-2
CAUTION: It is possible to damage the inverter or other devices if your application
exceeds the maximum current or voltage characteristics of a connection point.
… 4-4
CAUTION: Be sure to turn OFF power to the inverter before changing the short
circuit bar position to change SR/SK. Otherwise, damage to the inverter circuitry
may occur.
… 4-8
CAUTION: Be careful not to turn PID clear ON and reset the integrator sum when
the inverter is in Run mode (output to motor is ON). Otherwise, this could cause the
motor to decelerate rapidly, resulting in a trip.
… 4-26
HIGH VOLTAGE: When set RDY function ON, there will be a voltage appear at
motor output terminals U, V and W even if the motor is in stop mode. So never
touch the inverter power terminal even the motor is not running.
… 4-31
HIGH VOLTAGE: Dangerous voltage exists even after the Emergency Stop is
activated. It does
NOT
mean that the main power has been removed.
