SilentWind 12V Guide D'installation Et D'utilisation page 10

Therefore how the mast is fitted to the deck/motorhomes is one of the most
important parts of the installation.
In order to eliminate harmonics and get the best performance out of the wind
generator we recommend the following when installing on a yacht/motorhome:
1) Do not position Silentwind in line with a backstay or centered position on
your stern. It needs to be positioned above the bimini, coach house or any other
construction. To work most efficiently and with the lowest noise emission all wind
generators need 'clean air'. During our own wind tunnel testing it was clearly
proven than any turbulence influenced wind generator performance. Any power
output date (Amps) are measured with the wind speed at the generator height not
on top of mast.
2) Avoid attaching the mast on any existing structure; for instance, a frame
which holds solar panels, biminis, rail fittings etc.
3) The three AC cables need to have the same diameter and the correct
mm2/AWG.
4) Make sure the electrical connections (crimping) are done 100%. Any
voltage drops can influence the control of brake functions. Use tinned copper
cables for marine installations.
5) The distance between the blade tips has to be the same. Take a measur-
ing tape and measure the distance from all three tips of the blades and adjust
accordingly. (Approximately 990 mm)
6) The arrow on the central nut should point towards generator head. Do not
over tighten the central nut.
7) All brackets, like mast clamps, need rubber strip insertions (3–4 mm thick -
ness and of medium density) between parts.
8) Use the supplied rubber insert between the generator and the mast.
9) An upper mast bracket should be installed approximately 20 cm below the
lowest part of the blades tip to stabilize the mast. The mast should be as short as
possible but high enough that the blades do not interfere with any objects and
nobody can get hit by the blades. Make sure that Silentwind gets 'clean air'.
10) Use rubber inserts between deck and mast base, rubber washer for
screws or bolts to remove any latent vibrations before entering the hull/motor
home.
11) After a week or so check the central nut which connects rotor hub to
shaft for tightness. Also check the 6 bolts which fix the blades to the hub.
12) To avoid any damage to the powder coated aluminum housing please
touch up any scratches, chipping of paint work during installation. Sea water will
penetrate the scratches and peel off the paint slowly.
13) As an additional precaution against electrolytic corrosion between
dissimilar metals, you can use 'Duralac' or 'Tefgel' on the 4 yaw bearing mast
bolts/nuts.
