Safety Precautions
● Cover the top of the product with cloth or paper during installation to prevent unwanted objects
such as metal chippings, oil, and water from falling into the equipment and causing faults. After
installation, remove the cloth or paper to prevent overtemperature 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 anti-vibration rubber under the motor frame or use the vibration
suppression function to reduce the resonance.
Wiring
● Do not allow non-professionals to perform equipment installation, wiring, maintenance, inspection,
or parts replacement.
● Cut off all power supplies before wiring. Wait for at least the time specified on the product warning
label after power-off so that residual voltage can discharge safely. Measure the DC voltage on the
main circuit to ensure that it is within the safe voltage range. Failure to comply may result in an
electric shock.
● Do not perform wiring, remove the product cover, or touch the circuit board with power ON. Failure
to comply may result in an electric shock.
● Ensure that the product is well grounded. Failure to comply may result in an electric shock.
● Never connect the power cable to an output terminal. Failure to comply may result in product
damage or even fire.
● When connecting a drive with the motor, ensure that the phase sequences of the drive and motor
are consistent to prevent motor reverse rotation.
● Ensure that the diameter and shield of the cables used meet corresponding requirements, and that
the shield of the shielded cables is grounded reliably at one end.
● Tighten terminal screws with tightening torque specified in this guide. Failure to comply may result
in overheat and damage to the connection parts or even fire.
● After wiring, check that each cable is connected properly, no screws or gaskets fall into the product,
and no cables are exposed. Failure to comply may result in an electric shock or product damage.
● Follow the proper electrostatic discharge (ESD) procedures, and wear an anti-static wrist strap
during wiring. Failure to comply may result in damage to the product or the circuit of the product.
● Use shielded twisted pair cables for the control circuit. Connect the shield to the product grounding
terminal. Failure to comply may result in product malfunction.
Power-on
● Before power-on, ensure that the product is properly installed, all cables are securely connected,
and the motor can be restarted.
● Before power-on, ensure that the power supply meets requirements. Failure to comply may result in
product damage or even fire.
● Do not open the cabinet or protective cover, touch any terminal, or dismantle any device or
component when the product is powered on. Failure to comply may result in an electric shock.
