A
CAUTION:
As
a
precaution
against
an
unintentional
start,
shut
off
the
20
Amp
DC
breaker
on
the
control
panel.
1.
Refer
to
the previous page that illustrates the various
AC
voltage output configurations for both
the
60 Hertz
and
50 Hertz applications. Select
the
configuration
for
the
HertziVoltage required.
2.
Reconfigure
the
12
AC
connections
on
the
tenninal
board carefully following the illustration. Reference
below
the
voltage sensing diagram
and
it;s
connections
to
the
AC
terminal block. There
are
three line
connections when needed and a neutral. These
connections
MUST correspond
to
and be connected
to
the
line
(L)
connections on the
AC
tenninal board
and
the
neutral connection
as
well
to
it's corresponding
connection. Failure
to
properly connect these voltage
sense connections can result in
an
AC
output voltage
fault shut down either
from
low or high
AC
voltage or
incorrect
AC
voltage displayed on the LCD
display.
NOTE:
When reconfiguring the
AC
output, ensure that the
A
VR
Neutral and line connections are properly connected
to
the
AC
temtinal block.
3.
111ere
are
Ull'ee
line
connections.
When
an
L3
is
not
present on the
AC
tenninal block, insulate and
tie
off
the
L3
connection
from
tl1e
Voltage
Sensing Board.
4.
Inside the control box, locate
the
ECU
and
position
the
HertzlFrequency dip switch in the correct position for the
HertzlFrequency desired.
S.
Verify
all
connections
are
correct
and
turn off
any
A C
panel breakers;
6.
Start
the
generator and monitor
the
AC
output voltage at
the generator's tenninal board. Line
to
line, line
to
neutral.
Adjust the voltage regulator board
as
needea
to
obtain the
correct voltage.
Check the generator hertzlfrequency with
your hertz
meter.
7.
Turn on the
AC
panel breakers
and
load unit and monitor
the
operation.
