Precautions:
1. Verify that the wind turbines output voltage matches the rated voltage of the battery.
2. Wire in the following order, first connect the positive and negative terminals of the battery, and then connect the three-phase voltage output of the fan.
3. Please carefully connect the battery and the wind turbines to the controller according to the instructions. Connecting the reverse polarity or the wrong position will cause the system to work abnormally and may even cause damage to the system components.
4. Although the controller has taken protective measures against various possible accidents, it is strongly recommended that users strictly abide by the operating procedures to prevent damage to the battery and controller.

Wiring:
1. Connect the "+" and "-" of the battery to the positive and negative terminals of the battery of the controller.
2. Connect the three-phase output voltage of the wind turbines to the three-phase voltage input terminal of the controller fan.
3. When manual brake is required, short the red thin wire to the positive battery, that is, complete the manual brake function. To cancel this function, just disconnect the thin red wire.
Indicator status:
When the controller green power (BATTERY) indicator is on, it indicates that the battery is connected properly.
When the controllers green fan access (WIND) indicator flashes, it indicates that the wind turbines is connected. The speed of the flashing reflects the speed of the fan.
When the controller red (BRAKE) indicator is on, the battery is fully charged, the wind turbines is automatically braked, or the brake is automatically activated due to overcurrent protections.
