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.
