Wiring
Main Circuit Input/Output
•Phase rotation of input terminals L1 (R), L2 (S), L3 (T) is available in either direction, clockwise and counterclockwise.
•When Inverter output terminals T1 (U), T2 (V), and T3 (W) are connected to motor terminals T1 (U), T2 (V), and T3 (W), respectively, motor rotates counterclockwise, viewed from opposite drive end, upon forward operation command. To reverse the rotation interchange any two of motor leads.
•Never connect AC main circuit power supply to output terminals
T1 (U), T2 (V), and T3 (W).
•Care should be taken to prevent contact of wiring leads with the 3G3XV cabinet, or a short-circuit may result.
•Never connect the power factor correction capacitor or noise filter to 3G3XV output.
•Never open or close contactors in the output circuit unless
Inverter is properly sized.
! Caution The withstand voltage between the motor's phases is insufficient.
When the motor is connected to the Inverter's output, a surge is generated between the Inverter's switching and the motor's coil.
Normally the maximum surge voltage is three times the Inverter's input power supply voltage (i.e., 600 V for 200-V class, and
1,200 V for 400-V class). Be sure to use a motor with a withstand voltage between the motor's phases that is greater than the maximum surge voltage. In particular, when using a 400-V-class
Inverter, use a special motor for Inverters.

! Caution Observe the following guidelines when wiring.
•Lead size should be determined considering voltage drop of leads. Select the lead size so that the voltage drop will be within
2% of the normal rated voltage. The voltage drop can be obtained from the lead resistance (R) in W/km, wiring distance (D) in meters, and current (I) in A using the following equation:
Phase-to-phase voltage drop in volts = √ 3 ×R ×D ×I ×10±3
•Insertion of AC reactor:
When the power supply capacity exceeds 600 kVA, connect an AC reactor at the Inverter input side for power supply coordination. This reactor is also effective in improving the power factor of the power supply.
•Wiring length between Inverter and motor:
If the total wiring distance between the Inverter and motor is excessively long and the Inverter carrier frequency (main transistor switching frequency) is high, harmonic leakage current from the cable will increase to affect the Inverter Unit or peripheral devices. If the wiring distance between the Inverter and motor is long, reduce the Inverter carrier frequency as shown below. The carrier frequency can be set with constant No. 40. For details, refer to 2-8-18 Carrier Frequency. The carrier frequency is set to 10 kHz at the factory prior to shipping.

Grounding |
Ground the casing of the 3G3XV using ground terminal G (E). |
|
|
•Ground resistance should be 100 W or less. |
|
|
•Never ground the 3G3XV in common with welding machines, |
|
|
motors, and other large-current electrical equipment, or ground |
|
|
pole. Run the ground lead in a separate conduit from leads for |
|
|
large-current electrical equipment. |
|
|
•Use the ground leads which comply with AWG standards and |
|
|
make the length as short as possible. |
|
|
•Where several 3G3XV Units are used side by side, all the Units |
|
|
should preferably be grounded directly to the ground poles. How- |
|
|
ever, connecting all the ground terminals of 3G3XV in parallel, |
|
|
and grounding only one of 3G3XV to the ground pole is also per- |
|
|
missible as shown below. However, do not form a loop with the |
|
|
ground leads. |

Precautions for Control Circuit Wiring
Take the following precautions when wiring.
1, 2, 3... 1. Separate the control signal line from power lines. Otherwise a malfunction might occur.
2.For the frequency setting signal (analog), use a shielded lead and be sure that the signal is terminated properly.
Connect shielded sheath to main circuit grounding terminal G (E).
Shielded Armor sheath
Never connect
Insulate these parts with insulating tape
3.The wiring length of the control signal line must be 50 m or less.
4.To drive the contact input signal by transistor, use one having
ratings of 50 V 50 mA or more. Circuit leakage current at signal OFF must be 100 μA or less.
5.To drive an inductive load (relay coil, etc.) by multifunction pho- to-coupler output, be sure to insert a free wheel diode.

1-5 Operation
1-5-1 Checking Before Operation
Check the following items after completion of installation and wiring:
•No fault in wiring. Especially, the power supply is connected to the output terminals T1 (U), T2 (V), and T3 (W).
•No short-circuit because of wiring contamination (dust, oil, etc.).
•Screws and terminals are not loosened. Wiring is provided properly.
•Wiring is not grounded.
•Load status is good.
For safe operation, before operation, the motor must be able to operate alone by separating it from the coupling or belt which connects the motor and machine.
When the motor is operated with the machine directly connected, pay close attention.

Standard 4-pole motor current value is set as the initial value. For details refer to 2-8-8 Electronic Thermal Overload Function.
Provide a thermal relay or thermal protector when more than one motor is operated simultaneously.
1-5-3 Test Run Method
The Inverter can be operated using the Digital Operator or control circuit terminal inputs. Models with Digital Operator are set to
ªOPERATOR MODE BY DIGITAL OPERATORº prior to shipping.
Operation Using the Digital Operator
This is the standard setting of Models with a Digital Operator; in this Mode, the Inverter is operated with the keys of the Digital
