Step 10:
Dynamically brake the EXCEL 1’s alternator by using the shorting function of the turbine control box.
Step 11:
Raise the tower following the procedures outlined by the tower supplier. Please make safety your top
priority.
Non-tilting Towers: On a non-tilting tower, such as a fixed guyed tower or a self-supporting pole
type tower, there are two general approaches that can be used: 1) assemble the tower and turbine to-
gether on the ground and then use a light-duty crane to set the tower in place, or 2) erect the tower and
then lift the wind turbine to the top with either a light-duty crane or a gin-pole.
A gin-pole, in this case, is a tower assembly tool that attaches to the tower and provides an arm with a
pulley so that parts can be hoisted above the top of the tower. Gin-poles are used by professional tower
erectors and we do not recommend their use by non-professionals. We know of at least one homeowner
who died while improperly using a gin-pole to install a small wind turbine (though not a Bergey turbine).
Wherever possible we strongly recommend assembling the tower and turbine on the ground. In this case
please follow the general procedure for turbine assembly provided in the preceding section. When raising
the tower you must lift the tower, not the EXCEL 1 wind turbine. The EXCEL 1 cannot support the weight
of the tower.
For customers installing a BWC EXCEL 1 on an existing fixed tower we recommend that you use a crane
to lower the tower so that you can attach the turbine on the ground. Alternatively, we recommend you
use a bucket-truck, like the type used by utility linemen. Check with local sign companies because they
often offer bucket-truck services at reasonable hourly rates. If neither of these approaches is possible
then we recommend that you engage the services of professional wind turbine or tower erectors to install
your wind turbine.
