protecting
itself
in
high
winds.
Because
the
tail
assembly
is
mounted
on
a
20
degree
pivot
bar
and
is
free
to
rotate,
the
tail
assembly
does
not
move
and
stays
“in
the
wind”.
When
the
wind
speed
lowers
to
28-­‐30
mph,
the
Windtura
750
unfurls
and
the
blades
and
generator
face
the
wind
again.
Because
the
Windtura
750’s
furling
mechanism
is
based
on
an
angled
tail
boom,
it
is
very
important
that
the
tower
is
installed
vertically.
Use
a
level
to
confirm
that
your
tower
is
mounted
vertically.
If
it
is
not,
you
will
have
to
adjust
the
tower
until
it
is
vertical.
A
tower
that
is
not
mounted
vertically
can
cause
the
Windtura
750
to
furl
at
an
undesignated
wind
speed.
Tips
and
tricks
when
not
using
a
slip
ring:
A
slip
ring
prevents
the
wires
inside
the
tower
pipe
from
not
twisting
when
the
wind
turbine
rotates
in
circles
to
track
the
wind.
While
a
slip
ring
is
a
handy
device
for
a
wind
turbine,
nearly
all
wind
turbines
can
operate
virtually
maintenance
free
without
a
slip
ring.
How
is
this
accomplished?
Well,
to
put
it
simply,
a
wind
turbine
is
just
as
statistically
likely
to
rotate
in
the
counter-­‐clockwise
(CCW)
direction
as
it
is
to
rotate
in
the
clockwise
(CW)
direction
when
tracking
the
wind.
So,
the
CCW
and
CW
turns
of
the
wind
turbine
tend
to
balance
each
other
out
over
time
and
this
prevents
the
tower
wire
from
becoming
twisted
or
“bunched
up”.
You
will
find
that
even
after
6
months
of
operating,
there
might
only
be
one
or
two
twists
in
the
tower
wire.
Every
3-­‐4
months,
you
should
check
your
tower
wire
for
twists
if
you
are
not
using
a
slip
ring.
If
you
find
any
twists,
then
untwist
the
wires.
There
is
a
simple
way
to
do
this
and
figure
below
illustrates
how:
