5. Turbine Installation

Appendix 1 is an Installation Planning Guide. It provides recommendations on tower heights and loca-

tions, electrical components, and wiring. Please read the Appendix on “How to Avoid the Most Com-

mon Mistakes when Installing an EXCEL 1”.

Tower Mounting: The EXCEL 1 wind turbine is attached to its tower by a three-sided, six fastener cast-

ing, shown in Figure 4, that is designed to fit inside a tube with an inner diameter of 108 mm (4.25 in).

(Note: EXCEL 1’s shipped prior to September 2003 were built to fit a tube with an 85 mm (3.35 in) inner

diameter.)

If you are using the BWC Tilt Tower then the EXCEL 1 will bolt directly in place. If you are mounting the

EXCEL 1 to a different type of tower then you will need to ensure that the tower meets the requirements

for EXCEL 1 towers (see Appendix) and that it has a proper adapter fitting for attaching the EXCEL 1

tower mount casting (also defined in the Appendix).

Once you have the proper mounting arrangement you can proceed with assembly of the wind turbine.

The fasteners on the EXCEL 1 are all metric.
