CAUTION
Always close the terminal cover before turning the input power ON.
Do not open the terminal cover while the power is ON.

The STOP button is not designed for emergency stop purposes. Prepare a
separate emergency stop button.
Failure to do so could lead to injury.
ATTENTION
The heat sink fins and brake resistor (dedicated option) can reach high
temperatures, so do not touch them.
Failure to do so could lead to burns.
The inverter can be easily set to run from low speeds to high speeds. Confirm
the tolerable speed range of the motor and machine before starting operation.
Failure to do so could lead to injury.
Prepare holding brakes when required.

Before turning power ON, check the following points again.
1) Check that all wiring is correct.
Reversed wiring between the power supply and the load, in particular, can
result in damage to the inverter.
2) Make sure the inverter rating and power supply voltages match each
other.
3) Make sure no power factor capacitor is connected to the motor, as it can
damage the inverter.
4) Before starting a trial run, check the set frequency.
