
Do not connect a braking resistor directly to the DC terminals P (+) and N (-), otherwise fire
may result.

Use wire gauge recommendations and torque specifications. (See Wire Gauge and
Torque Specification in section 3.6)

Never connect input power to the inverter output terminals U/T1, V/T2, W/T3.

Do not connect a contactor or switch in series with the inverter and the motor.

Do not connect a power factor correction capacitor or surge suppressor to the inverter
output.

Ensure the interference generated by the inverter and motor does not affect peripheral
devices.
1.3 Before Operation
Warning

Make sure the inverter capacity matches the parameters 13-00.

Reduce the carrier frequency (parameter 11-01) If the cable from the inverter to the
motor is greater than 80 ft (25m). A high-frequency current can be generated by
stray capacitance between the cables and result in an overcurrent trip of the inverter,
an increase in leakage current, or an inaccurate current readout.

Be sure to install all covers before turning on power. Do not remove any of the covers
while power to the inverter is on, otherwise electric shock may occur.

Do not operate switches with wet hands, otherwise electric shock may result.

Do not touch inverter terminals when energized even if inverter has stopped, otherwise
electric shock may result.
1.4 Parameters Setting
Caution

Do not connect a load to the motor while performing a rotational auto-tune.

Make sure the motor can freely run and there is sufficient space around the motor
when performing a rotational auto-tune.
1.5 Operation
Warning

Be sure to install all covers before turning on power. Do not remove any of the covers
while power to the inverter is on, otherwise electric shock may occur.

Do not connect or disconnect the motor during operation. This will cause the inverter
to trip and may cause damage to the inverter.

Operations may start suddenly if an alarm or fault is reset with a run command active.
Confirm that no run command is active upon resetting the alarm or fault, otherwise
accidents may occur.

Do not operate switches with wet hands, otherwise electric shock may result.

It provides an independent external hardware emergency switch, which emergently
shuts down the inverter output in the case of danger.

If automatic restart after power recovery (parameter 07-00) is enabled, the inverter will
start automatically after power is restored.

Make sure it is safe to operate the inverter and motor before performing a rotational
auto-tune.

Do not touch inverter terminals when energized even if inverter has stopped, otherwise
electric shock may result.

Do not check signals on circuit boards while the inverter is running.
After the power is turned off, the cooling fan may continue to run for some time.
Caution

Do not touch heat-generating components such as heat sinks and braking resistors.
