direct sunlight, strong electric field, strong magnetic field, and strong vibration.
●Avoid storing this product for more than three months. Long‑term storage requires
stricter protection and necessary inspections.
●Pack the equipment strictly before transportation. Use a sealed box for long‑distance
transportation.
●Never transport the equipment with other equipment or materials that may harm or
have negative impacts on this equipment.

‑6‑
Installation
●Installation must be carried out by the specialists who have received the necessary
electrical training and understood enough electrical knowledge. Ensure no
unprofessional person has access to the equipment.
●Read through the guide and safety instructions before installation.
●Do not install this equipment in places with strong electric or magnetic fields.
●Before installation, ensure that the installation position has sufficient mechanical
strength to support the weight of the device. Failure to comply will result in a mechanical
danger.
●To avoid electric shock, do not wear loose clothes or accessories.
●When this equipment is installed in a cabinet or final equipment, use a cooling device
(such as a fan or air conditioner) to cool the environment down to the required
temperature. Failure to comply may result in equipment over‑temperature or a fire.
●Do not retrofit this equipment.
●Do not fiddle with the bolts used to fix equipment components or the bolts marked in
red.
●When this product is installed in a cabinet or terminal device, protection measures such
as a fireproof enclosure, an electrical enclosure, or a mechanical enclosure must be
provided. The IP rating must meet IEC standards and local laws and regulations.
●Before installing devices with strong electromagnetic interference, such as a transformer,
install a shielding device for the equipment to prevent malfunction.
●Install the equipment onto flame retardant materials, such as metal. Keep the equipment
away from combustible objects. Failure to comply will result in a fire.

‑7‑
●During installation, use a piece of cloth or paper to cover the top of the product to
prevent metal chippings, oil, and water from entering into the product when drilling
holes. Failure to comply will cause product malfunctions. After installation, remove the
cloth or paper for effective ventilation and cooling.
●If the device running at a constant speed begins to run at variable speeds, resonance
may occur. In this case, install the vibration‑proof rubber under the motor frame or use
the vibration suppression function to reduce resonance.
Wiring
●Only professionals are allowed to perform installation, wiring, maintenance, inspection
or parts replacement on the equipment.
●Before wiring, cut off all the power supplies of the equipment. Wait as specified on the
product warning sign before further operations because residual voltage exists after
power‑off. Measure the DC voltage of the main circuit and make sure that it is below the
safety voltage. Failure to comply will result in an electric shock.
●Never perform wiring, remove the product cover, or contact the PCB at power‑on. Failure
to comply will result in an electric shock.
●Check that the equipment is grounded properly. Failure to comply will result in an
electric shock.Separate grounding or single‑point grounding, other than common
grounding, is recommended.

‑8‑
●Do not connect the input power supply to the output end of the equipment. Failure to
comply can result in equipment damage or even a fire.
●When connecting a drive to the motor, make sure the phase sequence of the drive and
motor are consistent to prevent motor reverse rotation.
●Cables used for wiring must meet cross sectional area and shielding requirements. The
shield of the cable must be reliably grounded at one end.
●Ensure that all cables are connected correctly. Cable sheath is not damaged, and no
screw or washer is left inside the equipment. Otherwise, electric shock or equipment
damage may occur.
●During wiring, follow the proper electrostatic discharge (ESD) procedure and wear an
antistatic wrist strap. Failure to comply can result in damage to the equipment or
internal circuits.
●In wiring the control circuit, use shielded twisted pair cable and connect the shield to the
PE terminal. Otherwise, the equipment may not function properly.
Power-on
●Before power‑on, check that the equipment is installed properly, the wiring is secure and
the motor can be restarted.
●Before power‑on, check 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 wiring terminals, or remove any part of the equipment at power‑on.
Failure to comply will result in an electric shock.

‑9‑
●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, ensure that the nominal voltage of the equipment is consistent with
the power supply voltage. Improper power supply voltage will cause a fire.
●Before power‑on, ensure that there are no people around the equipment, motor and
other machines. Failure to comply will result in injuries or death.
Operation
●Only qualified professionals are allowed to run the equipment. Failure to comply can
result in injury or death.
●Do not touch any wiring terminals or remove any part of the equipment during
operation. Failure to comply will result in an electric shock.
●Do not touch the equipment enclosure, fan, or resistor to sense the temperature. Failure
to comply may result in burns.
●Prevent metal or other objects from falling into the device during operation. Failure to
comply may result in a fire or product damage.
Maintenance
●Only professionals are allowed to perform installation, wiring, maintenance, inspection
or parts replacement on the equipment.
●Do not perform maintenance on the equipment with power ON. Failure to comply can
result in the risk of electric shock.
●Before maintenance, cut off all power supplies of the device and wait for a period
specified on the warning label of the device.
●When a PM motor rotates, its terminals will produce induced voltage even if the motor is
powered off. Failure to comply will result in an electric shock.

‑10‑
●Perform routine and periodic inspection and maintenance on the equipment according
to maintenance requirements and keep a maintenance record.
Repair
●Only professionals are allowed to perform installation, wiring, maintenance, inspection
or parts replacement on the equipment.
●Do not repair the equipment after power‑on. Failure to comply can result in the risk of
electric shock.
●Before device inspection and repair, cut off all power supplies of the device and wait for a
period specified on the warning label of the device.
●Submit the repair request according to the warranty agreement.
●When the fuse is blown, the circuit breaker trips, or the earth leakage circuit breaker
(ELCB) trips, wait for a period specified on the warning label of the device before you
energize or operate the device. Failure to comply may result in personnel injuries or
damage to the device.
●When the device is faulty or damaged, require professionals to perform troubleshooting
and repair by following repair instructions and keep a repair record.
●Replace quick‑wear parts of the equipment according to the replacement instructions.
●Do not operate damaged device. Failure to comply may result in personnel injuries or
death or greater damage to the device.
●After replacing the equipment, perform wiring inspection and parameter settings again.
Disposal
●Dispose of retired equipment in accordance with local regulations and standards. Failure
to comply may result in property damage, personal injuries, or even death.
●Recycle retired equipment by observing industry waste disposal standards to avoid
environmental pollution.
