Security advices
Wind turbines are dangerous devices because of their high rotational frequency and the
created voltage, so please read these security advices carefully:
Mechanical risks:
The rotating rotor is a big danger because it turns invisible, when a certain wind speed is
reached. The angles of the rotor blades are very sharp-edged because of their aerodynamical
body. Thereforeyou can hurt yourself even at slowly-rotating rotors. Never touch the rotating
rotor, never try to stop it with your hands, mount the turbine only at locations where nobody
has the possibility to touch it easily- that is very important, especially on boats!
The rotor blades are manufactured from plastics which even bears up against high wind
speeds, nevertheless, you should keep distance to the rotating blades. Severe injuries can
occur if a rotor blade breaks off. Especially this is the case when a blade was hit by a flying
object. When a blade is damaged, you should stop the turbine immediately. When a rotor
blade is damaged, the whole tower can be in danger because the generator can get a big
unbalance. So please pay attention to the choice of your installation location. Only mount the
wind generator to the tower when the connections of the charge controller or the feed-in
converter are disconnected and bypassed (short-circuit of the generator may only be done
when the rotor turns faster than 100 times per minute) or a rotor blade is tied to the tower, so
that you cannot get hurt by the rotating rotor.
The tower and the mounting to the tower have to resist the forces that are created by the wind
force and by the strain. For this matter, a professional technician should be entrusted with the
installation.
Please notice that you have to mount the tower with the help of at least two persons and that
you have to follow the instructions and rules of the accident Ruihuaion and insurance
association. When you mount the tower, please notice that no other persons may stand next to
the tower. Encumbrances have to be secured with linkages during the process of lifting.
Elektrical risks:
A coasting wind turbine, especially the 48 V version, is able to create a DC voltage of more
than 200 V. Please connect these devices only when you are technically experienced. These
voltages can be fatal if you do not act accordant the instructions. Never touch uninsulated
wire ends. Notice that uninsulated wires can do harm.
The wire, connective elements, plugs and other electrical components have to be dimensioned
adequately at width, therewith wires do not warm up and cause a fire. The maximum current
inside the wire can be up to 50 Ampere at a turbine 600 Watt 12V.
Wires have to be laid securely in order to protect wires from mechanical damages. An open
wire is very dangerous!
For fuse protection, you have to install a fuse to the feed cable, please do that as near as
possible to the battery. A short-circuit of the battery cables and/or power lines has to be
avoided on any account.
