If the fastening torque is too high, this will destroy or damage the blades. If the
fastening torque is not high enough, the blades can get lose. A wrong fastening
torque is a considerable safety risk.
Before the final tightening of the blade screws, make sure that the distance
between the blade tips is exactly the same, in order to avoid vibrations. Move each
rotorblade in running direction towards the edge of the blade guide of the
hub. The running direction is clockwise looking from the front. Then fix the
blades as described above.The blades should then be ‘in balance’: The blades
have been balanced statically and dynamically.
In case of damage of only one blade you can buy a single one. When ordering one
blade, be sure to inform RULIS Electrica, Lda. on the exact weight of the undam -
aged blades.
An incorrect tightening torque represents a significant security risk.
Regularly control the fixation of the blades!
After attaching the blades to the hub, the set is fixed to the generator shaft with the
enclosed screw nut (use the enclosed hexagon socket screw key). After that, snap
the nose cone into place on the assembly hub. (see page 17, sketch 5, 6 and 7)
Then you must connect the three AC outlet cables which have to be led from the
SILENTWIND to the charge controller.
Attention: During this procedure the 3 AC wires of the extention cable at the end
must be connected together. Otherwise the rotor system may start running and you
can get injured.
Finally you mount the SILENTWIND on the mast. Fix the 4 hexagon screws to the
yaw clamp after inserting the rubber pad (see page 18, sketch 8)
When tightening the screws take care for a uniform, circumferential tightening of
the 4 screws. The tightening should be made with small increments in order to
avoid damaging the marine grade painting.
