5. Setup and Installation

Before beginning installation, ensure the power source is disconnected. The controller features a simple structure with separate wires for various connections. Refer to the images below for visual guidance on the controller's wiring.

5.1 Identifying Connections:

Figure 5.1: Detailed view of all wires and connectors on the controller.

The controller comes with various color-coded wires and connectors. It is crucial to correctly identify each wire's function before making connections. Common connections include:

• Power Wires: Thick red (positive) and black (negative) wires for battery connection.
• Motor Wires: Three thick wires (often yellow, green, blue) for connecting to the brushless motor phases.
• Hall Sensor Wires: A set of thinner wires (typically red, black, yellow, green, blue) for Hall effect sensors in the motor (if applicable).
• Throttle Wires: Usually three wires (red, black, green) for throttle input.
• Brake Wires: Wires for connecting to brake levers (often two wires, one for high-level brake, one for low-level brake).
• Ignition/Key Switch Wires: For turning the controller on/off.
• Self-Learning Wires: (If present) Used for automatic motor phase identification.
• Other Accessory Wires: May include wires for speedometer, cruise control, anti-theft, etc.

5.2 Installation Steps:

1. Mount the Controller: Securely mount the controller to the frame of your electric vehicle using the integrated mounting brackets. Ensure good airflow around the controller for optimal heat dissipation.

2. Connect Motor Wires: Connect the three thick motor phase wires from the controller to the corresponding wires on your brushless motor. If your motor has Hall sensors, connect the Hall sensor wires as well.
3. Connect Battery Wires: Connect the thick red wire from the controller to the positive terminal of your 36-48V battery and the thick black wire to the negative terminal. Double-check polarity.
4. Connect Throttle: Connect the throttle wires to the designated throttle connector on the controller.
5. Connect Brake Levers: Connect the brake wires from your brake levers to the controller's brake input.
6. Connect Ignition/Key Switch: If your system uses an ignition switch, connect its wires to the controller.
7. Self-Learning (if applicable): If your controller has self-learning wires, connect them temporarily. Power on the system, and the motor should spin. If it spins in the wrong direction, disconnect and reconnect the self-learning wires to reverse direction. Once the correct direction is established, disconnect the self-learning wires.
8. Secure all Connections: Ensure all connections are tight and insulated to prevent accidental disconnections or short circuits.

6. Operating Instructions

1. Power On: Turn on the main power switch or ignition key for your electric vehicle. The controller will initialize.
2. Throttle Control: Gently twist the throttle to engage the motor. The controller will provide smooth acceleration.
3. Braking: Apply the brake levers. The controller is designed to cut power to the motor when brakes are engaged, providing sensitive braking control.
4. Speed Control: The controller maintains a constant speed based on throttle input and provides efficient power delivery.
5. Power Off: Turn off the main power switch or ignition key when not in use.

7. Maintenance

• Regular Inspection: Periodically check all wire connections for tightness and signs of wear or corrosion.
• Cleanliness: Keep the controller clean and free from dust, dirt, and debris. Use a dry cloth for cleaning.
• Avoid Moisture: Ensure the controller remains dry. If it gets wet, allow it to dry completely before powering it on again.
• Heat Dissipation: Verify that the controller's aluminum casing is not obstructed, allowing for proper heat dissipation.
• Storage: When not in use for extended periods, store the controller in a dry, cool environment.
