Wiring of the Main Circuit
(Terminal block type)
F-frame, 200 V type
•Wiringshouldbeperformedbyaspecialistoranauthorizedpersonnel.
•Donotturnonthepoweruntilthewiringiscompleted.
•Nevertouchtheterminaltowhichhighvoltageisapplied.Thereisariskofelectric
shock.
• Tips on Wiring
1)Takeoffthecoverxingscrews,anddetachtheterminalcover.
2)Makewiring
 Useclamptypeterminalsofroundshapewithinsulationcoverforwiringtotheter-
minalblock.Forcablediameterandsize,referto“DriverandListofApplicablePe-
ripheralEquipments”(P.B14).
 Tightentheterminalblockscrewwithatorquebetween1.0and1.7N

• Check the name plate of the driver for power
specifications.
• Provide a residual current device. The residual current
device to be the one designed for "Inverter" and is
equipped with countermeasures for harmonics.
• Provide a circuit breaker.
• Make sure to provide a noise filter.
• Provide coil surge suppression units to the coil of the
Magnetic Contactor recommended by manufacturer.
Never start/stop the motor with this Magnetic
Contactor.
• Provide an AC Reactor.
• Don't disconnect the short bar between B1 and B2.
Disconnect this only when an external regenerative
register is used.
• Do not connect anything to NC.
• Match the colors of the motor lead wires to those of the
corresponding motor output terminals (U,V,W).
• Avoid shorting and grounding.
Don't connect the main power.
• Earth-ground this.
• To prevent electric shock, be sure to connect the ground
terminal ( ) of the driver, and the ground terminal
(ground plate) of the control panel.
• The ground terminal ( ) must not be shared with other
equipment.
Two ground 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 immediate
stop signal.
• The holding Brake has no polarity.
• For the capacity of the holding brake and how to use it,
refer to P.B43, "Specifications of Built-in Holding Brake".
• Provide a varistor.
• Connect a 10 A fuse in series with the varistor.
Ground resistance: 100 Ω max.
For applicable wire, refer to P.B14.

How to connect
1.Peelofftheinsulationcoverofthecable.
•Forsinglewire(Pleaseobeythelengthingure.)
•Forstrandedwires(ferrulesmustbeusedasillustratedbelow).
Example:
Ferrules with plastic insulating sleeve (AI series, Phoenix Contact, Ltd.)
1)Peeloffthesheathsothattheconductorportionofthecablewillprotrudefrom
thetipoftheferrule.(Itshouldprotrude
 1mmormorefromtheferrule.)
2)Insertthecableintotheferruleandcrimp
itwithanappropriatecrimpingtool.
3)Aftercrimping,cutoffthecableconductor
portionprotrudingfrom the ferrule. (The
allowableprotrudinglength aftercutting
shouldbe0to0.5mm.)
