WARNING
1, 2, 3... 1. After turning off the main circuit power supply, do not touch cir-
cuit components until the “CHARGE” indicator is extinguished.
The capacitors are still charged and can be quite dangerous.
2. Do not change the wiring while power is applied to the circuit.
3. Do not check signals during operation.
4. Be sure to ground 3G3XV using the ground terminal G (E).
5. Never connect main circuit output terminals, T1 (U), T2 (V), T3
(W), to AC main circuit supply.
Caution
1, 2, 3... 1. All the constants of 3G3XV have been adjusted at the factory.
Do not change their settings unnecessarily.
2. Do not perform withstand voltage test on any part of the 3G3XV
Unit. This electronic equipment uses semi-conductors and is
vulnerable to high voltage.
1-3 Installation
1-3-1 Location Location of the equipment is important to achieve proper perfor-
mance and normal operating life.

Operator only by main circuit wiring. When these models are oper-
ated by control circuit terminals, control constant change is
required. For details refer to

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), respec-
tively, motor rotates counterclockwise, viewed from opposite
drive end, upon forward operation command. To reverse the rota-
tion 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 insuffi-
cient.
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 maxi-
mum 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 Ω/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 coordina-
tion. 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 tran-
sistor switching frequency) is high, harmonic leakage current
from the cable will increase to affect the Inverter Unit or periph-
eral 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 fre-
quency is set to 10 kHz at the factory prior to shipping.
Wiring distance between Inverter and motor Up to 30 m Up to 50 m Up to 100 m Over 100 m
Allowable carrier frequency
(Corresponding setting for constant no. 40) 15 kHz max. (6) 10 kHz max. (4) 5 kHz max. (2) 2.5 kHz max. (1)
Grounding Ground the casing of the 3G3XV using ground terminal G (E).
•Ground resistance should be 100 Ωor 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.

1-4-4 Control Circuit
Control Circuit WiringThe control signals are connected by screws. The following figure
shows the relationship between I/O signals (factory preset values)
and screw terminal numbers. The terminal functions shown in the
figure indicate standard setting prior to shipping. Since Operation
Mode from the Digital Operator is set for the Model with the Digital
Operator, it is necessary to change the control constants when
operation is performed from the control circuit terminals. For
details, refer to
2-8-2 Operation Mode Selection .

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.

Never connect
Insulate these parts
with insulating tape
Connect shielded sheath

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 wir-
ing:
•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 prop-
erly.
•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 con-
nects the motor and machine.
When the motor is operated with the machine directly connected,
pay close attention.
