● Equipment installation, wiring, maintenance, inspection, or parts replacement must be
performed only by professionals.
● Before wiring, cut off all the power supplies of the equipment, and wait for at least the
time designated on the equipment 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 will result in an 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 can result in electric
shock.Separate grounding or single‑point grounding, other than common grounding, is
recommended.
● 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, 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.
● 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.
