Installation
● Cover the top of the product with a piece of cloth or paper during installation. This is to
prevent unwanted objects such as metal chippings, oil, and water from falling into the
product and causing faults. After installation, remove the cloth or paper on top of the
product to prevent over-temperature caused by poor ventilation due to blocked
ventilation holes.
● Resonance may occur when the equipment operating at a constant speed executes
variable speed operations. In this case, install the vibration-proof rubber under the
motor frame or use the vibration suppression function to reduce resonance.

Wiring
● Equipment installation, wiring, maintenance, inspection, or parts replacement must
be performed only by professionals.
● Before wiring, switch off all power supplies of the device. Wait for at least the time
designated on the warning label before further operations because residual voltage
still exists after power-off. After waiting for the designated time, measure the DC
voltage in the main circuit to ensure the DC voltage is within the safe voltage range.
Failure to comply can result in electric shock.
● Do not perform wiring, remove the equipment cover, or touch the circuit board and
other exposed live parts with power on. Failure to comply can result in electric shock.
● Make sure that the equipment and product are grounded properly. Failure to comply
can result in the risk of electric shock.
● Do not connect the power cable to output terminals of the equipment or product.
Failure to comply may cause equipment damage or even a fire.
● When connecting a drive with the motor, make sure that the phase sequences of the
drive and motor terminals are consistent to prevent reverse motor rotation.
● Cables used must comply with corresponding cross-sectional area and shielding
requirements. The shield of the shielded cable must be grounded at one end properly.
● Tighten the terminal screws with the torque specified in the user guide. Insufficient or
excessive torque may cause overheating and damage to the joint, which could result
in fire.
● After wiring is done, ensure that all cables are connected properly and no screws,
washers or exposed cables are left inside the equipment. Failure to comply could
result in electric shock or equipment damage.
● Avoid direct skin contact with enclosure edges and cut surfaces during operation.
● Route cables carefully during wiring. Avoid pressing them against sharp edges, which
may cause squeezing or cutting. It is recommended to use protective sleeves or route
cables away from such edges.
● If the enclosure has a protective film, remove it only after installation is completed and
all work involving sharp edges has been finished.
● During wiring, follow the proper electrostatic discharge (ESD) procedures, and wear
an antistatic wrist strap. Failure to comply may result in damage to the equipment or
internal circuits.
● Use the shielded twisted pair cable to wire the control circuit, and connect the shield
to the grounding terminal of the equipment. Failure to comply may result in
equipment malfunction.

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.
