cable gland nut. It is important to firmly tighten the cable gland nut (See Figure 4 above)
because it supports the weight of the wires hanging down the tower. Failure to tighten the
cable gland properly could cause the tower wires to slip downward and put tension on the
three wires coming out of the generator. This could cause damage to the generator.
For towers over 25 feet tall, a stainless steel hose clamp needs to be firmly clamped
around the three tower wires directly above the cable gland nut (See Figure 4 above). Stainless
steel hose clamps can be purchased from local hardware stores. The hose clamp adds
secondary support so that the tower wires do not slip down the tower and put unnecessary
tension on the three generator wires. This is necessary for towers over 25 feet due to the
added wire weight in tall towers.
Next, connect the three tower wires to the three wires exiting the back of the
generator. Take great care in making sure these wire connections are strong and have good
continuity. It is highly advisable to cover these wire connections with outdoor rated heat shrink
tubing to prevent possible wire shorts and to protect the wire connections from the outdoor
elements.

Section 3.0: Attaching the blades to the hub
Figure 5
Be
careful
not
to
hit,
bend
or
damage
the
blades
while
attaching
the
blades
to
the
hub
as
this
could
make
the
blades
unbalanced!
Note:
The
blades
should
be
mounted
so
that
they
curve
away
from
the
wind
turbine.
If
you
are
standing
in
front
of
the
wind
turbine
with
the
blades
facing
you,
the
blades
will
curve
outward
and
towards
you.
Step 1:
Locate the bag which is labeled “Blade to Hub Fastener Set”. This bag should contain
the following fasteners: 15 stainless steel bolts, 15 stainless steel k-‐lock nuts, and 15 stainless
steel flat washers.
