WARNING
3)

Do not check signals during operation .
CAUTION
An inverter is a device which
converts
three-phase AC commercial power
sup-
ply
to DC with an inverter
section,
producing
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 .
1) After turning OFF the main circuit power supply, do not touch circuit
components 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
.
4) Be sure to ground VS-616G3 using the ground terminal G (E) .
5)

Never connect main circuit output terminals T 1 (U), T2 (V), T3 (W)
to
AC main circuit power supply .
1)

All the constants of VS-616G3 have been adjusted at the factory
.

Do not
change their settings unnecessarily .
2)

Do not 'perform any dielectric tests on any part of the VS-616G3 unit .
The VS-616G3 contains
semi-conductor devices and is vulnerable to damage
from high voltage .
3)

The control PC board employs CMOS ICs
which are easily damaged by
static electricity . Do not touch
the
CMOS
elements .
4)

Make sure to tighten
screws
on the main
circuit and control circuit terminals
.
