5. Настройка и установка
Follow these steps to correctly install and wire your motor speed controller.
Инструкции по подключению:

Figure 5.1: Wiring diagram illustrating the connection points for power input and motor output.
- Потребляемая мощность: Connect your DC power supply to the terminals labeled 'Input positive 6-60V' (positive) and 'negative power supply' (negative). Ensure the voltage находится в диапазоне постоянного тока 6–60 В.
- Выход двигателя: Connect your DC motor to the terminals labeled 'motor positive' (positive) and 'motor negative' (negative).
- Безопасные соединения: Tighten all screw terminals to ensure a secure and stable connection. Loose connections can cause overheating or malfunction.
Always double-check your wiring before applying power to prevent damage to the controller or motor.

6. Инструкция по эксплуатации
Once the controller is correctly wired and powered on, you can begin operating your DC motor.
- Включение питания: Apply power to the controller. The LED display will illuminate, showing the current speed percentage.
- Start/Stop Function: The rotary knob also functions as a start/stop switch. A short press of the knob will start or stop the motor.
- Регулировка скорости: Rotate the knob clockwise to increase the motor speed and counter-clockwise to decrease it. The LED display will show the speed as a percentagе (0-100%).
- Setting Mode (Advanced): A long press of the rotary knob will enter the setting mode for advanced parameters. Refer to specific product documentation or manufacturer support for details on advanced settings if needed.
