4. Setup and Installation
Follow these steps for proper installation of the controller:
- Preparation: Ensure the e-bike's power is off and the battery is disconnected. Identify a suitable mounting location for the controller, away from direct heat, moisture, and physical impact.
- Motor Connection: Connect the motor's 9-conductor waterproof cable to the corresponding port on the controller. Ensure the connection is firm and secure.
- Battery Connection: Connect the controller's power input cables (typically red for positive, black for negative) to your 36V or 48V battery. Double-check polarity before connecting.
- Display/Throttle Connection: Connect your KT series display unit and throttle to their respective ports on the controller. The controller supports a speed adjustment range of 1-4.2V.
- Brake Levers: Connect your brake levers to the controller. The controller uses a low-level brake input signal.
- Light Cable (if applicable): If your model includes a light cable, connect it to your e-bike's lighting system.
