44
・Always close the terminal cover before turning ON the
inlet power.
・Do not open the terminal cover while the power is ON.
Failure to do so may result in an electric shock or fire.
・Do not operate the switches or dials with wet hands.
Failure to do so may result in an electric shock.
・Do not touch the inverter terminals when the inverter
power is ON or even when the inverter is stopped.
Failure to do so may result in an electric shock.
・The STOP button is not designed for emergency stop
purpose, so set a separate button for emergency stop.
Failure to do so may result in injury.
・The heat sinks and braking resistors are at high
temperature, so do not touch them.
Failure to do so could lead to burn.
・The inverter can easily be switched to high speed from
low speed, so confirm the allowable range of the motor
and machine before making settings.
Failure to do so could lead to injury.
・Set separate holding brakes if required.
Failure to do so could lead to injury.
・Before turning on the power, check the following points again.
1. Check if all wirings are correct or not again.
Reversed wirings between power supply and load in
particular could damage the inverter.
2. Check if the voltage rating of the inverter matches
with power supply.
3. Check if a phase-lead capacitor is connected to the motor.
Connection of phase-lead capacitor could result in
faults to the inverter and capacitor.
4. Confirm the set frequency before starting a trial operation.
