they can break due to ropes or other objects touching the blades in very strong
winds.
If one of the blades is damaged, activate the brake function manually with the stop
switch of the charge controller. If one of the blades is damaged, the rotor system will
be out of balance which may be a risk for the whole mounting construction. This has
to be considered before mounting the windgenerator in a safe position.
Before you install the windgenerator on a mast construction make sure that the 3-
phase wiring is disconnected from the charge controller or secure one blade so that
the system cannot turn. You can also connect the 3 AC wires to block the system
during mounting. Another possibility to install the system is to attach the hub with the
blades to the shaft at the very end of the mounting procedure. The mast must be well
fixed so that it is safe in strong wind and adverse sea conditions. Furthermore the
mast-fixation and the mast-stays should be assembled in a way that applied
vibrations will be not enhanced. Please ask a professional who is able to assess the
load that the mounting system can handle in strong wind conditions.
2.2. Electrical risks
An idle running windgenerator can generate a considerable AC voltage per phase.
Only connect all components if you are familiar with electric wiring. The high voltage
can cause serious injuries and fire if you do not pay attention to safety. Caution
recommended for cardiac pacemakers users, etc. Never touch the open end of the
wires. The current when charging the batteries can reach more than 30A DC. The
whole wiring electric components and connection points must be able to carry a
current of 40 A. Find information about suitable cable dimensions on page 9.
Warning: Wires with insufficient diameters can cause fire.
Make sure the wires are placed so that mechanical damages cannot occur. A
damaged cable is a severe safety risk. Install a fuse to the batteries positive pole as
close as possible to the battery. The required value of the fuse depends on the rated
current of the devices connected to the charge controller. Please contact a
professional for this purpose. We recommend a fuse with the double nominal current
of the connected devices.
Warning: When connecting the batteries, sparks can arise.
A short circuit is to be avoided.
Always ensure sufficient ventilation!
The electrical installation should be carried out by persons with appropriate technical
skills and knowledge. Before a storm the SILENTWIND should be manually stopped
with the stop switch on the charge controller. In case of storms we recommend fixing
one rotorblade to the mast due to the risk of damage by flying objects.
2.3. Installation risks
Only use or build mounting/support systems that can handle the load of the generator
and the blast pressure of the wind in any condition.
Working on the mounting system should only be carried out on a calm day. Make
sure that nobody is close to the mast.
