If
the
grid
type
is
set
to
240
VAC
without
neutral,
then
the
display
will
be
looked
as
the
figure
shown
below.

Three
(3)
seconds
later,
the
LCD
will
show
the
voltage
setting
for
the
inverter
to
drop
the
grid
connection.
The
settings
of
the
Vl
‐
nH
and
its
clearing
time
will
be
displayed.
The
Vl
‐
nH
setting
is
the
phase
‐
to
‐
neutral
(rms)
high
threshold
voltage
setting
at
which
point
the
inverter
disconnects
its
output
from
the
AC
power
grid
when
abnormally
high
phase
‐
to
‐
neutral
AC
voltage
is
detected.
After
the
setting
of
the
Vl
‐
nH
is
displayed,
the
setting
of
the
Vl
‐
nL
will
be
displayed
for
3
seconds.

Three
(3)
seconds
later,
the
inverter
displays
the
setting
of
the
VacH
which
is
the
phase
‐
to
‐
phase
(rms)
high
threshold
voltage
setting
at
which
point
the
inverter
disconnects
itself
from
the
grid
when
abnormally
high
phase
‐
to
‐
phase
AC
voltage
is
detected.
Also,
the
setting
of
the
clearing
time
which
is
the
total
duration
of
time
to
disconnect
the
output
from
the
AC
grid
is
displayed.
This
delay
is
necessary
to
avoid
nuisance
trips.
After
the
settings
of
the
VacH
and
its
clearing
time,
the
settings
of
the
VacL
and
its
clearing
time
will
be
displayed
for
three
(3)
seconds.
The
display
Vl
‐
nH/Vl
‐
nL
is
only
for
208/240/277VAC
with
neutral
setting,
VacH/VasL
is
only
for
240
or
208
without
neutral,
they
would
not
display
at
the
same
time.

Then
the
high
and
low
threshold
settings
of
the
AC
frequency
and
the
associated
clearing
time
will
be
shown
for
three
(3)
seconds.
When
the
AC
frequency
exceeds
the
high
or
low
threshold
setting,
the
inverter
will
disconnect
its
output
from
the
AC
grid.
