Chapter 3 Operation

DANGER

1, Only turn on the input power supply after replacing the front

cover. Do not remove the cover while the inverter is

powered up.

2, When the retry function is selected, do not approach the

inverter or the load, since it may restart suddenly after

being stopped.

CAUTION

1, Since the stop key can be disabled by a function setting, install

a separate emergency stop switch.

2, Since it is very easy to change operation speed from low to

high speed, verify the safe working range of the motor and

machine before operation.

3, Do not check signals during operation.

4, All inverter parameters have been preset at the factory. Do not

change the settings unless it is required. Failure to observe

these precautions may result in equipment damage, serious

personal injury or death.
