8. DC Electrical Preparations
Lay all necessary DC cabling before the next steps of installation except
the last meters from the turbine (top end of tower) to the lower end of the tower. Pre-
pare necessary cable ducts.
Set
-
up and install the automatic storm control in a separate box (yellow mark) next to
the inverters place. Install an AC switch that controls the energy supply of the automatic
storm control (green mark). This switch may later be used as a manual brake for the
wind turbine as the automatic control stops operation in case of a voltage drop.
The switch may only be operated every five minutes to allow cool
-
down of the relay!
Make the necessary DC connections between automatic storm control and inverter. See
wiring diagram on the next page for details.
7. Mounting Preparation
Attach a fitting ring terminal to the end of your DC cable to ensure easy and quick
connection to the inverter later on. If you use more than a single cable make sure that
the connection is safe and durable (e.g. MC connectors).
Mark the + and the
-
pole
clearly and unmistakably!
The turbine nacelle is now prepared for mounting on a suitable mast.
Write down the serial number of the SkyWind turbine. You will later need it for your
warranty certificate.
