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.
