4. the blades Especially on boats ensure a sufficient height above deck The blades are produced from carbon fibre which is extremely solid even in high wind speeds Therefore keep away from the turning blades in any case However they can break because of ropes or other parts touching the blades in very strong winds If one of the blades is damaged activate the brake function manually with the stop switch of the charge controller If one of the blades is damaged the rotor system will be out of balance which may be a risk for the whole mounting construction This has to be considered before mounting the windgenerator in a safe position Before you install the windgenerator on a mast construction make sure that the 3 phase wiring is disconnected from the charge controller or fix one blade so that the system cannot turn You can also connect the 3 AC wires to block the system during mounting Another possibility to install the system is to screw the hub with the blades to the shaft at the very end of the mounting procedure The mast must be well fixed so that it is safe in strong wind and sea conditions Furthermore the mast fixation and the mast stays should be well assembled that applied vibrations will be not enhanced Please ask a professional who is able to assess the load that the system generates in strong wind conditions 2 2 Electrical risks An idle running windgenerator can generate an AC voltage of 40V AC 15A per phase Only connect
5. 3 phase AC power The power of the energy increases in line with the wind speed exponentionally This means that a double wind speed generates octuple power This must be especially considered in storm conditions Our spb blades are produced of high tensil carbon fibre and are hand laminated with epoxy resin This material provides the maximum consistency at lowest weight This material is also used in Formula 1 and airspace industry Therefore these CF blades are extremely light but resist even strongest wind conditions They have been successfully tested at Deutsche WindGuard according to DIN EN 61400 2 VDE 0 127 2 at windspeed of 122 km h at 5480 RPM This is an equivalent of sonic velocity at the tips of the blades For every day use and safety reasons we have eguipped the charge controller with an electronical and manual stop switch 6 Diameters of cables System voltage 12 Volt Distance from 0 9 10 19 20 29 30 44 45 69 70 110 windgenerator to the charge controller in m Cable cross section mm 6 10 16 25 35 50 AWG 10 8 6 4 2 1 Distance from the charge 0 9 10 19 20 29 30 44 45 69 70 110 contr to the battery in m Cable cross section mm 10 16 25 35 AWG 8 6 4 2 o System voltage 24 Volt Distance from 0 9 10 19 20 29 30 44 45 69 70 110 windgenerator to the charge controller in m Cable cross section mm 2 5 4 6 10 16 25 AWG 14 12 10 8 6 4

11. noise emission is very low you can operate the SILENTWIND in neighbourhoods and on sailing yachts without annoying your neighbours Our charge controller HYBRID 600 is suitable for 12 and 24 volt usage and can be connected to the SILENTWIND and solar panel Another advantage of the SILENTWIND is that it does not have any inbuilt electronics which means that there is hardly any maintenance work on the mounted windgenerator The electric power is led down to the charge controller by 3 cables The hand laminated carbon fiber blades were successfully tested in a wind tunnel up to wind speeds of 35m s 63 knots according to DIN EN 61400 2 Therefore you need not worry about the SILENTWIND in any storm conditions For maintenance work there is an additional manual stop switch 2 Safety instructions Due to the high RPM and the electric energy that windgenerators generate their use may be dangerous Therefore carefully read the following safety instructions 2 1 Mechanical risks For various reasons the turning rotor system must be handled with caution You cannot see the end of the blades in high wind speeds so that you do not recognise the inherent danger Due to their aerodynamic shape the blades have very sharp edges that may hurt you in high wind conditions Never ever try to touch the turning rotor system Never ever try to stop the turning rotor system manually Make sure that you install the windgenerator in a position that nobody can touch
