Caution
Prohibited
Do not touch inverter terminals when electrical power is going to the inverter even if the motor is
stopped.
Touching the inverter terminals while power is connected to it may result in electric shock.
Do not touch switches when the hands are wet and do not try to clean the inverter with a damp cloth.
Such practices may result in electric shock.
Do not go near the motor in alarm-stop status when the retry function is selected.
The motor may suddenly restart and that could result in injury.
Take measures for safety, e.g. attaching a cover to the motor, against accidents when the motor
unexpectedly restarts.
Mandatory
action
If the inverter begins to emit smoke or an unusual odor, or unusual sounds, immediately turn power off.
If the equipment is continued in operation in such a state, the result may be fire. Contact your Toshiba
distributor for repairs.
Always turn power off if the inverter is not used for long periods of time.
Turn the input power on only after attaching the terminal block cover.
When enclosed inside a cabinet and used with the terminal block cover removed, always close the
cabinet doors first and then turn the power on. If the power is turned on with the terminal block cover or
the cabinet doors open, this may result in electric shock.
Make sure that operation signals are off before resetting the inverter after malfunction.
If the inverter is reset before turning off the operating signal, the motor may restart suddenly causing
injury.
Caution
