Safety Information
- Always disconnect power before performing any installation, maintenance, or troubleshooting.
- Ensure all connections are secure and correctly polarized to prevent damage to the controller or other components.
- Avoid exposing the controller to water, excessive moisture, or extreme temperatures.
- Do not attempt to open or modify the controller casing, as this may void the warranty and pose a safety risk.
- Consult a qualified technician if you are unsure about any installation steps.
Setup and Installation
Refer to the wiring diagram below for correct connection of the controller to your electric vehicle components. Ensure all connections match the specified colors and functions.
Detailed wiring diagram illustrating connections for battery, motor, throttle, key switch, brake switch, brake light, and indicator.
Wiring Connections:
- Battery Connection: Connect the battery wires to the corresponding terminals on the controller. Typically, red is positive (+) and black is negative (-).
- Motor Connection: Connect the motor wires (blue + and white -) to the motor output terminals.
- Throttle (Speed Governor): Connect the throttle unit. This typically uses a 1-4V signal for speed control.
- Key Switch: Connect the key switch wires. Important: The two wires of the key switch connector must be connected together (jumped) for the unit to power on and function.
- Brake Switch: Connect the brake switch wires. When activated, this switch cuts power to the motor.
- Brake Light: Connect the brake light wires (small red, small black) to the brake light connector.
- Indicator: Connect the indicator wires (small red, small black) for status display.
- Charging Port: Connect the charging port if applicable.
Ensure all connectors are fully seated and secure. The controller features rubber grommets for wire protection and a rugged aluminum housing for durability and heat dissipation.

Operating Instructions
Once the controller is correctly installed and all connections are secure:
- Ensure the key switch is in the 'ON' position (or the wires are jumped as per installation).
- Apply power to the system.
- Use the throttle (speed governor) to control the motor speed. The throttle typically operates within a 1-4V range.
- Engage the brake switch to cut power to the motor and activate the brake light.
Maintenance
- Keep the controller clean and free from dust and debris.
- Periodically check all wiring connections for tightness and signs of wear or corrosion.
- Ensure the controller's aluminum housing is not obstructed to allow for proper heat dissipation.
- Avoid using harsh chemicals or abrasive materials for cleaning.
