Regulator Installation
It is essential to follow these instructions carefully in the process of
installing the equipment. Any installation that does not meet these
requirements will not meet the necessary conditions to cover the equipment under
warranty in case of breakdown.
The installation of the equipment should only be done by specialized personnel.
The regulator is totally isolated. This means that there is insulation between positive
and negative poles, the wind turbine terminals and the chassis. There are no
connections between any of these points. So, the positive and negative poles of DC
Voltage (of the batteries) must be totally isolated from the input phases of the wind
turbine, from the ground of the installation, phase and neutral of inverters, etc. In
short, they must be totally isolated poles.
If you put some kind of busbar, you have to respect the wire sections and not build
up cascade configurations with the equipment. It is advisable to install the regulator
directly to batteries. For wiring selection, the section tables in the annex Sections
and Wiring must be respected. If you want to install a busbar, you must respect the
section of each equipment to calculate the total section of the busbar.
The installation must be properly grounded. The regulator chassis must be
connected to the same earth ground as inverters and other equipment. The
grounding wire of the regulator must be at least 6mm2.
If there is a fuel generator in the installation, its earth ground does not need to be at
the same point as the Wind + regulator. In fact, it is recommended to be different
ones.
The wind turbine must always be connected to the controller when stopped. It is
NOT possible to connect the regulator while the wind turbine is working since it can
cause over voltages and therefore damage to the equipment.
