System Configuration and Wiring
Wiring of the Main Circuit (A to D-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) Peel off the insulation cover of the cable.
(Observe the dimension as the right fig. shows.)
2) Insert the cable to the connector detached
from the driver. (See P.37 for details.)
3) Connect the wired connector to the driver.

Fuse (5A)
Ground resistance : 100 Ω max.
For applicable wire,
refer to P.B14 and B15.
• 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.
• Connect L1 and L1C, and L3 and L2C at single phase
use (100V and 200V), and don't use L2.
• Match the colors of the motor lead wires to those of the
corresponding motor output terminals (U,V,W).
• Don't disconnect the shorting cable between RB2 and RB3 (C
and D frame type). Disconnect this only when the external
regenerative register is used.
• Avoid shorting and ground fault. Don't connect the
main power.
*Connect pin 3 of the connector on the driver side with pin 1
of the connector on the motor side.
• 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.
