come in contact with the inverter case.
Do not perform a dielectric voltage withstand test (megger) on the inverter this will result in inverter
damage to the semiconductor components.
Caution
The line voltage applied must comply with the inverter’s specified input voltage.
Connect braking resistor and braking unit to the designated terminals.
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.
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.
