AVANTI Service Lift for Wind Turbines
2.4.2 Supply cable
a) The length of the cable depends on the height
of the tower and the positioning of the power
outlet. The cable length is determined prior to
ordering. The power cable is marked with its
length; check for accuracy before installing.
b) Minimum cross-sectional dimension of the
supply cable. Important with increased distance
between grid connection, generator, and
traction hoist, respectively:
c) Use heavy rubber cable ducts for fastening live
wire to service lift.
d) An installed generator will have to provide at
least 2.5 times the output of the traction hoist.
2.4.3 Power connection
a) Push the EMERGENCY STOP button
b) Check that the various stop switch cables and
safety brake cable are connected to the power
cabinet according to colour code.
c) Place or hang the cable collect bin underneath
the Ø200 mm hole in the platform.
d) If possible hang the bucket in the full length of
the webbing. Keep the webbing as long as
possible (Fig. 9c).
e) Cut the transport strips and tape which hold
the wire inside the bin and connect the cable
suspension (Fig. 9) to the eyebolt underneath
the service lift floor.
f) Connect the socket to the lift plug on the back
of the lift.
g) Connect the power cable plug to the grid: 400V
/ 3Ph + 0 + gnd. / 50 Hz
680V / 3Ph + gnd. / 50 Hz Pre-fuse: 16 A.
h) Turn the EMERGENCY STOP button (Fig. 10
and Fig. 10a) clockwise to deactivate.
i) The power is turned on and the green indicator
on the electrical control box lit. In order for the
service lift to be operational the door must be
locked and the HAND/AUTOM switch must be
in HAND mode.
The wiring diagram is found in the electrical control
box.
Important:
If the traction hoist does not start, two
phases in the supply connection might
have been switched around the phase
protection relay. Remedy: Have an electri-
cian check the phase lay.
