Figure 10: Turbine Mounting - Bergey Tilt Tower Installation Manual

The tower wiring is connected to the EXCEL1 wind turbine at the slip-ring using the two
small screws on the positive and negative slip ring terminals. The best way to do this is
with ring terminals chosen for your tower wire type. The polarity of the connections is
marked. If your conductors are color-coded we recommend making note of the colors
connected to positive and negative leads.
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 10. 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 ft off the ground to provide room to assemble the EXCEL1 tur-
bine. 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 six M10-1.5 x 20mm
bolts and six flat washers. We require applying Loctite 242 (Thread Locking Com-
pound) to the threads prior to installation to reduce the likelihood of loosening due to vi-
bration. Use a torque wrench to achieve the proper fastener torque on the tower mount-
ing bolts. The required torque is 45 ft-lbs.
Step 4:
Complete the wiring to the PowerCenter before adding the blades. This is recommend-
ed so that you can test the DC polarity of the wiring by spinning the alternator by hand.
It is very important that the polarity [positive (+) and negative (-)] is correct when the tur-
bine is connected to the PowerCenter. The best way to ensure this is to complete the
