9. Inspect the mainframe for cracks.
10. Remove the slip-ring cover plate. Make the following inspections:
A. Check brushes for ease of movement in the brush holder.
B. Check slip rings for signs of arcing damage.
C. Check that no grease from the yaw bearings has leaked on to the slip-
rings.
11. Inspect damper. Some leakage around the front seal is okay.
12. Inspect the furling cable (particularly at the ball end/fork attachment to the tail
boom) and furling cable conduit.
13. Check for cracks or loose hardware on the tail boom and fin.
14. Check the tail pivot pin and particularly its fasteners.
15. Close the nacelle and check that all of its fasteners are secure.
16. While descending the tower, inspect the following:
A. Check that the tower wiring is properly secure.
B. Check all fasteners.
C. Look for any cracks in the tower structure.
D. Check the condition of the guy wire attachment.
E. Check the furling cable.
17. Check the furling winch and make sure that the furling cable is not twisted up. If the
cable is twisted up, check the swivel.
18. Check the connection on all ground rods and hardware.
19. Remove the alternator shorting connection. Check the disconnect switch.
20. Switch the disconnect switch to "OFF" and unfurl the wind turbine. Listen to the
sound of the machine as it speeds up. No mechanical sounds, such as a "clunking"
or "banging," should be heard. Also watch for any new or significant vibration. The
turbine operation should be smooth.
21. Inspect the wire run, particularly all electrical connections.
22. Use a Meggar to check the three-phase wiring from the turbine to the controller (the
procedure is the same as used for commissioning).
23. Use a VOM to check that the three legs of the AC output of the wind turbine are
balanced.
24. Check condition of all wiring connections into and out of the Powersync II.
