System Configuration and Wiring
Wiring of the Main Circuit (E and F-frame)
• Wiring should be performed by a specialist or an authorized personnel.
• Do not turn on the power until the wiring is completed.
Tips on Wiring
1) Take off the cover fixing screws, and detach the terminal cover.
2) Make wiring
Use clamp type terminals of round shape with insulation cover for wiring to the terminal block. For cable
diameter and size, rater to "Driver and List of Applicable Peripheral Equipments" (P.B14 and B15).
3) Attach the terminal cover, and fix with screws.
Fastening torque of cover fixed screw in less than 0.2 N•m.

• Check the name plate of the driver for power
specifications.
• Provide a circuit breaker, or a leakage breaker. The
leakage breaker to be the one designed for
"Inverter" and is equipped with countermeasures for
harmonics.
• Provide a noise filter without fail.
• Provide a surge absorber to a coil of the Magnetic
Contactor. Never start/stop the motor with this
Magnetic Contactor.
Connect a fuse in series with the surge absorber.
Ask the manufacturer of the Magnetic Contactor for
the fuse rating.
• Provide an AC Reactor.
• Don't disconnect the short bar between B1 and B2.
Disconnect this only when an external regenerative
register is used.
• Match the colors of the motor lead wires to those of
the corresponding motor output terminals (U,V,W).
• Avoid shorting and ground fault.
Don't connect the main power.
• Earth-ground this.
• Connect the protective earth terminal ( ) of the
driver and the protective earth (earth plate) of the
control panel without fail to prevent electrical shock.
• Don't co-clamp the earth wires to the protective
earth terminal ( ) . Two terminals are provided.
• Don't connect the earth cable to other inserting
slot, nor make them touch.
• Compose a duplex Brake Control Circuit so that the
brake can also be activated by an external
emergency stop signal.
• The Electromagnetic Brake has no polarity.
• For the capacity of the electromagnetic brake and
how to use it, refer to P.50, "Specifications of Built-in
Holding Brake".
• Provide a surge absorber.
Connect a 5A fuse in series with the surge absorber.
