Figure 6, Tower Mounting for the XL.1
Tilt-up Type Towers: If you have a tilting
tower, such as the BWC Tilt.Tower, the following
procedure is recommended:
Tools Required:
 17 mm box end wrench
 17 mm socket and ~ 300 mm (12”) ratchet
drive
 8 mm socket or wrench
 pliers
 crimpers for wiring terminals (U-shaped
crimp preferred over straight crimp)
 thread locking compound (like Loctite 242)
 tape measure, 12 ft.
Procedure:
Step 1:
With the tower tilted down, place the powerhead
of the wind turbine near the top end of the tower.
The tower wiring is connected to the XL.1 wind
turbine at the slip-ring using two small screws and
ring terminals crimped to the two conductors.
BWC does not supply these ring terminals. Cut
the outer insulation on the wire back about 60 mm
(2.5 in). Strip the insulation off the outer 12 mm
(1/2 in) of each conductor and crimp on the ap-
propriate ring terminals. Attach the two power
conductors to the slip-ring assembly with the
screws provided. The polarities of the connec-
tions are marked. If your conductors are color-
coded we recommend making note of the colors
connected to positive and negative leads.
Caution
Do not use the box lugs supplied for the
PowerCenter connections instead of
ring terminals. The box lugs could short
circuit against the tower tube and dam-
age the alternator.
Caution
Be very careful with the washers on the
slip-ring terminals. DO NOT let them
fall into the alternator. If they do, you
must disassemble the alternator and
remove them before completing the in-
stallation.
The slip ring assembly is not designed to support
the weight of the down-tower wire. A strain reliev-
ing installation is required, as shown in Figure 7.
If possible put a loop in each wire to wrap around
the wire ties. Use the two nylon cable ties pro-
vided to secure the tower wiring to the tower
adapter casting. After completing the connec-
tions, pull on the tower wire to make sure that it is
secure before mounting the wind turbine on the
tower.
Step 2:
Raise the tower about 1 meter (3 ft) off the ground
to provide room to assemble the XL.1 turbine. We
recommend fashioning a temporary support stand
to hold the tower up during turbine assembly.
Step 3:
Mount the wind turbine tower adapter to the top of
the tower using the six M10 x 35mm bolts and six
washers. We strongly recommend applying Loc-
tite 242 (Thread Locking Compound) to the
threads prior to installation to reduce the likelihood
of loosening due to vibration. We recommend
using a torque wrench to achieve the proper fas-
