General Safety Instructions
● Cover the top of the equipment 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
equipment and causing faults. After installation, remove the cloth or paper on the top of
the equipment 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, cut off power connections with all equipment. Residual voltage exists
after power cut‑off. Therefore, wait at least the time designated on the equipment
warning label before further operations. Measure the DC voltage of the main circuit and
make sure it is below the safe voltage, otherwise there will be the danger of electric
shock.
● Do not perform wiring, remove the equipment cover, or touch the circuit board with
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.
● Do not connect the input power supply to the output end of the equipment. Failure to
comply will result in equipment damage or even a fire.
● When connecting a drive to the motor, check that the phase sequences of the drive and
motor terminals are consistent to prevent reverse motor 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.
● Fix the terminal screws with the tightening torque specified in the user guide. Improper
tightening torque may overheat or damage the connecting part, resulting in a fire.
● After wiring is done, check that all cables are connected properly and no screws,
washers or exposed cables are left inside the equipment. Failure to comply may result in
an electric shock or equipment damage.
● During wiring, follow the proper electrostatic discharge (ESD) procedure, and wear an
antistatic wrist strap. Failure to comply will damage the equipment or the internal
circuits of the equipment.
● Use shielded twisted pairs for the control circuit. Connect the shield to the grounding
terminal of the equipment for grounding purpose. Failure to comply will result in
equipment malfunction.
