6. Nacelle Finalization
Mount the nacelle cover again using the screws marked in yellow. Fix the yellow screws
with 2 Nm torque and Loctite 243.
During installation the turbines yaw
-
axis can be locked to make installation easier and
safer. This can be done by tightening the yaw
-
lock screw (red). Before the turbine can
begin operation this screw has to be loosened so that half its lengh is outside the turbi-
ne. After installation fix the screw in loosed position using Loctite 243.
The bearing
-
lockers should be checked (green). If these are too tight the turbine won´t
be able to yaw correctly. If these are too loose the turbines operation might be louder
than expected. Check manual for details.
Never use any other screws than those delivered with the turbine! In case of loss of
screws please contact SkyWind Energy.
5. Nacelle Cable Connection
Measure up 6 mm² (AWG 9 or 10) solar cable so that the lengh will be sufficient from
turbine to the inverter. The DC cable should not be longer than 20 m. Check the manual
for details on cross
-
sections.
Lead the cable from the down end of the mast adapter into the nacelle (see picture).
Please note that the generator must not be dismounted to do so.
Lead one cable left to the generator, one cable to the right of the generator (see pic-
ture) towards the generators connection cables. Apply plenty of grease to the upper
end of the mast adapter.
Connect the generator cables to your DC cables using crimp connectors.
Fix the cables to the nacelle using four zip
-
ties at the dedicated wholes in the nacelle
(see picture).
Check that the generator is bolted down very tightly to the nacelle. Tighten the screws
and fix them using Loctite 243 if needed.
