Nature Power 2000W-48V Marine Grade Wind Turbine (70701) - Manual (Page 10)

Important
7-2 Length of the extension cable that leads from the wind generator
to the battery
The wind generator has an output voltage of 50V.
Connect either a single 48V battery or four 12V batteries in a serial
connection.
7-3 D.P.D.T. (Double pole double throw) blade switch
To ensure safety, the wind generator is equipped with an emergency stop
feature (See D.P.D.T diagram). In the event of an emergency stop, the
wind generator’s power supply must be shut off for approximately 10
seconds before being restarted. In order to facilitate turning the power
on/off, we recommend the installation of a D.P.D.T. BLADES SWITCH
between the wind generator and the battery (see next section)

7.Connecting the System
7-1 Before connecting
The 48V model is used as a standalone system (off-grid system). A 48V
battery is required for the system. The following explains how to connect
the wind generator power cable (approximately 20inches[500mm] long)
and provides a typical example of a wind turbine system connection.
Important
*Pay attention to the + and – terminals when connecting the power cable
to the battery. Reverse connection will cause serious damage.
(Be aware that any damage to this product caused by improper connection
is NOT covered by the warranty. Connect the cables to the correct terminals).
The wind generator is designed to use double wires with a length of 15m
(49ft) and a gauge of AWG #8 (8mm²) between the wind generator and the
batteries. However you can select the appropriate wire gauge according to
the distance. Please check section 9 (“Considerations when choosing
Peripheral Materials/Devices”). Make sure to include the height of the tower.
