Owner`s manual

Tilt-up Type Towers: If you have a tilting tower, such as the BWC Tilt Tower, the following proce-

dure 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 EXCEL 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 appropriate ring terminals. Attach the two power conductors to the slip-ring

assembly with the screws provided. The polarities of the connections 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 relieving

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 provided to secure the tower wiring to the tower adapter casting. After

completing the connections, 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 3’ off the ground to provide room to assemble the EXCEL 1 turbine. We recom-

mend fashioning a temporary support stand to hold the tower up during turbine assembly.
