Power-on
● Before power-on, check that the equipment is installed properly with reliable wiring
and the motor can be restarted.
● Before power-on, make sure that the power supply meets equipment requirements to
prevent equipment damage or even a fire.
● After power-on, do not open the cabinet door or protective cover of the equipment. Do
not touch any terminals, or remove any part of the equipment at power-on. Failure to
comply will result in an electric shock.
● Perform a trial run after wiring and parameter setting to ensure that 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. Using an incorrect supply
voltage may cause a fire.
● Before power-on, check that no one is near the equipment, motor, or other
mechanical parts. Failure to comply may result in personal injury or even death.
Operation
● The equipment must be operated only by professionals. Failure to comply can result in
injury or death.
● Do not touch any connecting terminals or disassemble any unit or component of the
equipment during operation. Failure to comply can result in electric shock.
The equipment is equipped with the automatic restart function. After power supply
recovery or fault clearance, do not enable this function when the equipment is
running, being inspected, or when personnel are in contact with the drive mechanism.
Before enabling the automatic restart function, check the following:
● No personnel are working on the load side, and no foreign objects cause blockages.
● All safety protection devices (such as safety doors, emergency stop circuits) are
properly engaged.
● Prominent "Automatic restart" safety warning signs have been posted on the
equipment and the site.
● Do not touch the enclosure, fan, or resistor with bare hands. Failure to comply may
result in burns.
● Prevent metal or other objects from falling into the equipment during operation.
Failure to comply may result in a fire or equipment damage.

result in an electric shock.
● Before maintenance, disconnect all the power supplies of the equipment and wait for
at least the time specified on the warning label.
● When using a permanent magnet (PM) motor, do not touch the motor terminals while
the motor is rotating, because induced voltage may be present at the terminals even
after the product is powered off. Failure to comply may result in electric shock.
● Perform routine and periodic inspection and maintenance on the equipment
according to maintenance requirements and keep a maintenance record.
Repair
● Equipment installation, wiring, maintenance, inspection, or parts replacement must
be performed only by professionals.
● Do not repair the equipment with power-on. Failure to comply may result in electric
shock.
● Before inspection or repair, disconnect all the power supplies of the equipment and
wait for at least the time specified on the warning label.
● Submit a request for repair based on the warranty agreement.
● When the fuse is blown or the circuit breaker or earth leakage current breaker (ELCB)
trips, wait for at least the time specified on the warning label before power-on or
other operations. Failure to comply may result in personal injury or death and
equipment damage.
● Troubleshooting and repair of a faulty or damaged equipment must be performed by
professionals based on the repair instructions, with the repair records kept properly.
● Replace quick-wear parts of the equipment according to the replacement instructions.
● Do not use damaged equipment. Failure to comply can result in death, personal
