Operations - Toshiba VF-S15 Instruction Manual

3. Operations

 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.
Prohibited
 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.
 If the inverter begins to emit smoke or an unusual odor, or unusual sounds, immediately turn the power
off.
Continuous use of the inverter in such a state may cause fire. Call your Toshiba distributor for repairs.
 Always turn the power off if the inverter is not used for long periods of time since there is a possibility of
malfunction caused by leaks, dust and other material. If power is left on with the inverter in that state, it
may result in fire.
 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
Mandatory
cabinet doors first and then turn the power on. If the power is turned on with the terminal block cover or
action
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, resulting
in injury.
 Do not touch heat radiating fins or discharge resistors.
These devices are hot, and you'll get burned if you touch them.

prohibited
 Observe all permissible operating ranges of motors and mechanical equipment. (Refer to the motor's
