5. Fit eight M20 x 45 bolts with a spring washer and then a regular washer and place the bolts to
join the 1
st
segment to the tower base plate (see Figure 13). Use WD-40 oil to lubricate the
bolts before placing them into the threaded holes. Fix the bolts cross wise with a torque of
434 Nm, going first 50% and then 100%.
! TIP:
When having trouble getting bolts into
threads, move the mast via gin-pole left to right or front to back. If necessary loosen slightly
pressure on the lifting cable but DO NOT relieve the pressure on the gin-pole.
Step 2: Disconnecting the lifting equipment
1. Unhook the lifting cable from the gin-pole and the lifting equipment.
2. Unhook the gin-pole from the connection cable.
3. Remove the M27 nuts and A 28 washers from the M27 threaded bar connecting the gin-pole
to the tower 1
st
segment and remove the gin-pole (see Figure 8).
4. Place the A 28 washers and M27 nuts back onto the M27 threaded bar to be used again for
the gin-pole if necessary.
5.
a. Use a 6 m ladder to climb up onto the tower and remove the shackle and the
connecting cable from position one (see Figure 10).
IMPORTANT:
Never perform this
job while the turbine is switched on.
b. Leave the connection cable onto the tower and fix it with rope or cable ties to the
tower. This will avoid the connection cable being get caught in the blades or
producing noise when vibrating against the tower with strong winds.
Step 3: Placing the tower junction box
1. Take the
B9/T tower junction box, remove the lid and push two M5 x 16 screws through the soft
component at the slotted fixing holes (see Figure 23). The screws have to be approximately
75 mm apart.
2. Place the junction box onto the tower 1
st
segment above the hole for wires and fix it with the
screws to the tower 1
st
segment and attach the junction box lid.
