36System Configuration and WiringWiring 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 Wiring1) Take off the cover fixing screws, and detach the terminal cover.2) Make wiringUse clamp type terminals of round shape with insulation cover for wiring to the terminal block. For cablediameter 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.Surge absorberMotorDC 24VPower supplyDC power supply for brakeNFB NF MCL1UVWEL2L3rtPB1B2UVWLGround resistance : 100Ω max. For applicable wire, refer to P.B14 and B15.RedBlackGreen yellowYellow (X2)• Check the name plate of the driver for powerspecifications. • Provide a circuit breaker, or a leakage breaker. Theleakage breaker to be the one designed for"Inverter" and is equipped with countermeasures forharmonics. • Provide a noise filter without fail. • Provide a surge absorber to a coil of the MagneticContactor. Never start/stop the motor with thisMagnetic Contactor. Connect a fuse in series with the surge absorber.Ask the manufacturer of the Magnetic Contactor forthe fuse rating. • Provide an AC Reactor. • Don't disconnect the short bar between B1 and B2.Disconnect this only when an external regenerativeregister is used. • Match the colors of the motor lead wires to those ofthe 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 thedriver and the protective earth (earth plate) of thecontrol panel without fail to prevent electrical shock. • Don't co-clamp the earth wires to the protectiveearth terminal ( ) . Two terminals are provided. • Don't connect the earth cable to other insertingslot, nor make them touch. • Compose a duplex Brake Control Circuit so that thebrake can also be activated by an externalemergency stop signal. • The Electromagnetic Brake has no polarity. • For the capacity of the electromagnetic brake andhow to use it, refer to P.50, "Specifications of Built-inHolding Brake". • Provide a surge absorber. Connect a 5A fuse in series with the surge absorber.WhiteFuse (5A)
