4) Extend the wires straight from the turbine and tape them together every 3 feet. They will be
much easier to push through the pipe as a group than one at a time.
5) If pipe insulation is to be used on the wires, a short piece (6 inches) should be taped
securely onto the wires every 3 feet or so. This will keep the wires from contacting the pipe
and transmitting turbine noise to the tower.
6) Slip the lower guy wire hanger (coupler) onto the lower tower pipe near its top (guy wires
toward the bottom).
7) Push the wires down through the lower pipe section. If it is too difficult to push the wires,
then slide a guy wire up through the pipe and tape the wires to it. Pull the wires through the
pipe using the guy wire.
8) Mount the turbine to the upper tower section as described in the turbine owners manual.
9) Position the upper and lower tower sections together and slide the lower guy wire hanger /
coupler over the joint. At this time tighten the upper (non guy wire) bolt to 18-20 ft.-lb.
This should hold the two sections together (the other bolt will be installed later).
Step 7: Attaching Guy Wires to Anchors
With the assembled tower laying on the ground the guy wires at the sides and rear of the tower
should now be attached. Make sure that the bottom of the tower is at the tower base so that the
distances from the anchors to the guy wire attachment points on the tower will be the same as when
the tower is vertical. Leave about 6 inches of slack in the wires to allow for any misalignment or
unnoted elevation differences (the wires will be adjusted more precisely later). The side wires can
be pulled to their anchors and attached using the wire rope thimbles provided with your tower kit.
The guy wires should arrive in a coil. Installation will be easier and kinking can be avoided if they
guy wires remain coiled until the layout is finalized.
Note: The thimbles may need to be spread open to install them on your anchors. This can be
done with a pair of pliers and the end of one of the tower tubes. Be sure to press the open end of
the thimbles back together (with pliers) before attaching the guy wires.
The rear wires length can be estimated by pulling them to a side anchor and placing a piece of tape
on the wire at the distance of the side anchor. The rear wires will then be attached to their
respective anchor at the point marked by the tape. This should make their length approximately
correct when the tower is up (again these will be readjusted, so don’t worry about a few inches one
way or the other). Make sure that none of the guy wires are crossed and that the side wires are
straight with no rear wires on top of them. Run the tail of each guy wire through the second clamp
twice, forming a safety loop. Attach all of the side and rear wires securely as shown in the drawing
with two clamps on each wire. Use 6-8 ft.-lb. of torque on each nut. It is important (for good
strength) that the saddle part of each clamp is on the loaded (tower) side of the guy wire.
