Fundamental Safety Instructions
● Before power‑on, check that the equipment is installed and wired properly and the
motor can be restarted.
● Check that the power supply meets equipment requirements before power‑on to
prevent equipment damage or a fire.
● After power‑on, do not open the cabinet door or protective cover of the equipment,
touch any terminal, or disassemble any unit or component of the equipment. Failure to
comply will result in an electric shock.
● Perform a trial run after wiring and parameter setting to ensure the equipment operates
safely. Failure to comply may result in personal injuries or equipment damage.
● Before power‑on, check that the rated voltage of the equipment is consistent with that
of the power supply. Failure to comply may result in a fire.
● Before power‑on, check that no one is near the equipment, motor, or machine. Failure
to comply may result in death or personal injuries.
Operation
● The equipment must be operated only by professionals. Failure to comply will result in
death or personal injuries.
● Do not touch any connecting terminals or disassemble any unit or component of the
equipment during operation. Failure to comply will result in an electric shock.
● Do not touch the equipment casing, fan, or resistor with bare hands to feel the
temperature. Failure to comply may result in personal injuries.
● Prevent metal or other objects from falling into the equipment during operation. Failure
to comply may result in a fire or equipment damage.
Maintenance
● Equipment installation, wiring, maintenance, inspection, or parts replacement must be
performed only by professionals.
● Do not maintain the equipment with power ON. Failure to comply will result in an
electric shock.
● Before maintenance, cut off all the power supplies of the equipment and wait for at least
the time designated on the equipment warning label.
● In case of a permanent magnet motor, do not touch the motor terminals immediately
after power‑off because the motor terminals will generate induced voltage during
rotation even after the equipment power supply is off. Failure to comply will result in an
electric shock.
