3. System Configuration and Wiring
Wiring of the Main Circuit (Terminal block type)
G-frame, 400 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 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, reter to "Driver and List of Applicable
Peripheral Equipments" (P.B16). Tighten the terminal block screw with a torque
between 2.0 and 2.4 N m (left side) and 1.0 and 1.7 N
•
3) Attach the terminal cover, and fix with screws.
Tighten the screw securing the cover with the torque written on P.B17.

current device to be the one designed for
"Inverter" and is equipped with countermeasures
for harmonics.

this Magnetic Contactor.
• Direct power supply for control circuit.

• Provide an AC Reactor
(to be supplied by customer)
DB1
• AC 3-phase power supply 400V for main circuit.
• The voltage applied across DB1 and DB2 must be

300 VAC or below or 100 VDC or below.
• Match the connector of the motor and driver "U, V,

• Avoid shorting and grounding.
NC
Don't connect the main power.
• For normal operation, do not disconnect the shorting

bar from DB3 and DB4: remove the bar only when
DB4 the external dynamic brake resistor is used.
• Earth-ground this.
NC
• To prevent electric shock, be sure to connect the
Right ground terminal ( ) of the driver, and the ground
side
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 polarities.
• For the holding brake power supply capacity and
how to use the brake, refer to "Specifications of
Built-in Holding Brake" on P.B47.
• Provide a varistor.
• Connect a 10A fuse in series with the varistor.
* Do not connect anything to NC.
