1-1 What is an “Inverter”?
An inverter is a device to convert a three-phase AC commercial power supply
to DC with an inverter section to produce AC variable frequency voltage from
this converted DC. This AC variable frequency voltage can then be used for
speed control of three-phase squirrel-cage induction motors.
DANGER! 1) After turning off the main circuit power supply, do not touch circuit compo-
nents until “CHARGE” lamp is extinguished. The capacitors are still charged
and can be quite dangerous.
2) Do not connect or disconnect wires and connectors while power is applied
to the circuit.
3) Do not check signals during operation.
4) Be sure to ground SYSDRIVE 3G3IV using the ground terminal G (E).
5) Never connect main circuit output terminals T1 (U), T2 (V), T3 (W) to AC
main circuit power supply.
Caution 1) All the potentiometers of SYSDRIVE 3G3IV have been adjusted at the fac-
tory. Do not change their settings unnecessarily.
2) Do not make withstand voltage test on any part of the SYSDRIVE 3G3IV
unit. It is electronic equipment using semi-conductors and vulnerable to high
voltage.
3) Control PC board employs CMOS ICs which are easily damaged by static
electricity. Do not touch the CMOS elements.
1-2 Receiving This SYSDRIVE 3G3IV has been put through demanding tests at the factory
before shipment. After unpacking, check for the following.
•Verify the part numbers with the purchase order sheet and/or packing slip.
•Transit damage.
If any part of SYSDRIVE 3G3IV is damaged or lost, immediately notify the
shipper.

1-4 Installation
Caution Never move, lift or handle the SYSDRIVE 3G3IV cabinet by front cover or
terminal stands. Lift the cabinet from the bottom.
1-4-1 Location Location of the equipment is important to achieve proper performance and
normal operating life. The SYSDRIVE 3G3IV units should be installed in ar-
eas where the following conditions exist.
•Ambient temperature: --10°to 40°C, 14°to 104°F (For enclosed type),
--10°to 45°C, 14°to 113°F (For open chassis type)
•Protected from rain or moisture.
•Protected from direct sunlight.
•Protected from corrosive gases or liquids.
•Free from airborne dust or metallic particles.
•Free from vibration.
•Free from magnetic noise.
Caution To house multiple SYSDRIVE 3G3IVs in a switchgear, install a cooling fan or
some other means to cool the air entering the inverter below 45°C(113°F).
1-4-2 Mounting Space
Install SYSDRIVE 3G3IV vertically and allow sufficient space for effective
cooling as shown below in Fig. 1.

2-1 ConnectionsThe following shows an interconnection diagram. With digital operator, the
motor can be operated by wiring the main circuit only. (Terminal shows
main circuit and control circuit)
Important Use listed closed-loop connectors sized for the wire gauge involved. Connec-
tors are to be installed using the correct crimp tool specified by the connector
manufacturer.
Caution The connections of control circuit terminals 1 through 27 do not follow the
terminal numbering order. To connect them properly, follow the figure below.

2-2 Molded-case Circuit Breaker (MCCB)
Be sure to connect MCCBs between power supply and SYSDRIVE 3G3IV
input terminals L1 (R), L2 (S), L3 (T). Recommended MCCBs are listed in the
table below.
When a ground fault interrupter is used, select the one with no influence for
high frequency, and setting current should be 200mA or over and operating
time, 0.1 s or over to prevent malfunction.

2-5 Control Circuit
The external interconnection wiring must be performed with following proce-
dures.
After completing SYSDRIVE 3G3IV interconnections, be sure to check that
connections are correct. Never use control circuit buzzer check.
(1) Separation of control circuit leads and main circuit leads:
Signal leads 1 through 20 must be separated from main circuit leads L1 (R),
L2 (S), L3 (T), B1/(+), B2, (--), B0/(--), T1 (U), T2 (V), T3 (W), and other power
cables to prevent erroneous operation caused by noise interference.
(2) Control circuit leads 9 10 18 19 20 (contact output) must be separated
from leads 1 to 8, 21 22 25 26 27 and 11 to 17.
Use the twisted shielded or twisted-pair shielded lead for the control circuit
line and connect the shield sheath to the inverter terminal 12 (G). See Fig. 3.

Section 2-5
(3) Wiring distance:
It is recommended that the wiring distance of the signal leads (1 to 20) be 50
meters (164 feet) or below.
2-6 Main Circuit Input/Output
(1) Phase rotation of input terminals L1 (R), L2 (S), L3 (T) is available in ei-
ther direction, clockwise and counterclockwise.
(2) 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.
(3) Never connect AC main circuit power supply to output terminals T1 (U),
T2 (V), and T3 (W).
(4) Care should be taken to prevent contact of wiring leads with SYSDRIVE
3G3IV cabinet, for short-circuit may result.
(5) Never connect power factor correction capacitor or noise filter to SYS-
DRIVE 3G3IV output.
(6) Never open or close contactors in the output circuit unless inverter is
properly sized.
2-7 Grounding
Ground the casing of the SYSDRIVE 3G3IV using ground terminal G (E).
(1) Ground resistance should be 100Ωor less.
(2) Never ground SYSDRIVE 3G3IV in common with welding machines, mo-
tors, and other large-current electrical equipment, or ground pole. Run the
ground lead in a separate conduit from leads for large-current electrical
equipment.
(3) Use the ground leads which comply with AWG standards and make the
length as short as possible.
(4) Where several SYSDRIVE 3G3IV units are used side by side, all the units
should preferably be grounded directly to the ground poles. However, con-
necting all the ground terminals of SYSDRIVE 3G3IV in parallel, and ground
only one of SYSDRIVE 3G3IV to the ground pole is also permissible (Fig. 4).
However, do not form a loop with the ground leads.

2-8 Test Operation
To assure safety, prior to test operation disconnect the coupling or belt which
connects the motor with the machine so that motor operation is isolated. If an
operation must be performed while the motor si directly connected to the ma-
chine, use great care to avoid any possible hazardous condition.
Check before turning power ON After completion of installation and wiring,
check for:
(1) proper wiring
(2) short circuit due to wire clippings
(3) loose screw-type terminals
(4) proper loads
Setting the line voltage selecting connector for the 400 V class 20.6 kVA and
above:
The line voltage selecting connector shown in Fig. 5 must be set according to
the type of main power source. Insert the connector at the position showing
the appropriate line voltage. The UNIT is preset at the factory for 460 line
voltage.
