DANGER

For safety reasons, do not install the wind generator before inspecting the durability/
quality of the pole and the area in which it will be installed. If the pole and the location
are not suitable, injury or death may result.

Install this product so that the tips of the rotor blades have at least 3.5m (11.5 f t)
clearance from any surrounding objects. After installation is complete, clear away
all scaffoldings, making sure that the rotor blades are far out o f re ac h of p eo pl e, p et s
and/or livestock.

Never touch a moving rotor blade by your hand or any other part of the body. The rotor
blades are sharp and accidental contact can result in death or severe injury.

The body of wind generator will also move in accordance with wind direction once it
begins to make contact with the wind. Exercise caution if it is necessary to approach
the wind generator to perform installation or maintenance work.

WARNING

Do not install the wind generator in close proximity to electric or telephone lines. A
fallen pole or contact between the rotor and electric/telephone lines could result in
electrocution, disconnection, damage or malfunction of the turbine.

Do not install the wind generator in close proximity to structures such as smokestacks
that attain extremely high temperatures. The heat could mel t th e in su la ti on o n el ec tr ic al
cables, resulting in electrocution, fire or other damage.

Do not install the wind generator if the pole to which it will be attached is not standing
straight up. The wind generator could fall, causing an accident or me ch an ic al
damage/malfunction.

Do not use the wind generator for any purpose other than generating electricity from
natural wind. Do not attempt to generate electricity by mounting the wind generator
on a moving vehicle. Do not use the wind generator in close proximity to an exhaust
duct or in any other extremely high-temperature environment. Doing so could result
in fire, injury, or damage to the wind generator.

Discontinue use if the lines or cables are damaged (i.e. exposed wires, cut cables,
plug damage). Continued use could result in electrocution, fire, or short circuits.

2

Do not pull on, excessively bend, or attempt to modify the wires/cables of the wind
generator. Doing so could result in cord damage, electrocution, or fire.

Never attempt to disassemble or modify the wind generator. Doing so could result
in electrocution, fire, or wind generator malfunction.

Due to conditions of use, this system may not continuously supply stable electrical
power. Do not attempt to use the electricity generated by the wind generator to
power medical devices or other equipment related to human life systems support.
Do not attempt to use the electricity generated by the wind generator to power
personal computers not equipped with batteries or other auxiliary power sources.

CAUTION

Observe all safety precautions when working on the wind generator in high
locations. Take care to ensure that hardware and other parts do not fal l fr om t he
wind generator. Falling parts can cause injuries or other accidents.

Before assembling the wind generator, secure adequate space to ensure that
work can be completed safely. Inadequate space can result in injur ie s or o th er
accidents.

3.Installation siting

Small changes in wind speed can have a dramatic effect on power
production. The location of your wind turbine should be carefully
considered.

Each installation is different and is often a compromise between tower
height, distance from the battery bank, local zoning requirements and
obstacles such as buildings and trees.
In general the higher the tower the greater the wind speed and ultimately
the power production. However, towers are expensive and can easily

exceed the cost of the turbine.
The minimum recommended tower height is 25 ft (7.6 m) on open ground
or 20 ft (6m) above nearby obstructions. Try to locate the wind turbine in
the “cleanest” turbulent free air as possible. Turbulence will reduce the
efficiency of the wind turbine and may accelerate wear on rotating
components.

Safety must be the primary concerned when selecting the mounting
location. Install wind turbine so there is no possibility of accidental contact
with rotating blades even if it requires installing the wind turbine in a less
than ideal location. Safety has precedence over efficiency.
