8) Prepare the Turbine Mount - If you have purchased a LE-600 mount bracket or tower from
a Leading Edge Turbines ’ dealer, then please refer to the separate installation instructions
supplied with the product. If you have sourced your own tower / mount bracket, 7 mm
diameter holes will need to be drilled in order to secure the turbine. These holes should be
drilled 14 mm and 29 mm from the top of the tower / mount bracket and should be
perpendicular to the surface and skewed by 90 degrees. The hole should penetrate both
sides and cross the centre line of the tubular section - see Fig-10.

9) Install the Transmission Cables - When your tower or mount bracket is ready to receive its
turbine, the next stage is to run the cables from the top of the tower to where the rectifier
box / electrical controller and batteries / grid-tie inverter will be located. Follow the table
below to select the correct wire size (cross-sectional area). This will vary depending on
your nominal battery voltage and the distance that the cables will be run. Careful selection
of the cable size is required. It will not only affect the safety of the system, but also the
overall efficiency. A cable of insufficient cable size will cause a voltage drop, wasting the
power that has been generated. The cable sizes listed below have been selected with
efficiency and cost in mind, as it is unlikely that your turbine will be running at full capacity
100% of the time. If in doubt, consult your local electrical supplier. The cable should be
installed in accordance with local electrical regulations and guidelines. If in doubt, use a
local electrical contractor to complete the cable installation.
Warning: If a cable of insufficient cross-sectional area is used, heat will build up in the cables
causing a potential fire hazard. Cable capacities quoted below are based upon ‘Tri - Rated’ cables
(BS6231).
