4.2. Controller Mounting

1. Select a secure location on your bicycle frame, away from moving parts and potential impact zones.
2. Ensure adequate airflow around the controller for optimal heat dissipation.
3. Mount the controller using appropriate fasteners (not included) to prevent movement during operation.

4.3. Wiring Connections

Connect the components to the controller using the provided 1T5 cable and individual connectors. Refer to the diagrams below for specific connections.

• Motor Connection: Connect the motor's 9-pin waterproof plug to the corresponding port on the controller. This 30A controller is typically suitable for 1000W motors.
• Power Connection: Connect your battery (36V/48V) to the XT60 power input on the controller.
• 1T5 Cable Connection: Plug the 1T5 cable into the designated port on the controller. This cable branches out to connect the display, throttle, and brake sensors.
• LCD8HUP Display: Connect the display to the 1T5 cable's display connector. The controller must be used with a KT series display.
• TT009 Thumb Throttle: Connect the thumb throttle to its designated connector on the 1T5 cable.
• Brake Sensors: Connect your e-bike's brake sensors to the 2-pin brake connectors on the 1T5 cable.
• KT-V12 PAS Sensor: Install the PAS sensor on your bicycle's crank arm and connect it to the controller's PAS input.
• Light Wire: If applicable, connect your e-bike's light to the dedicated light wire from the controller.

This image provides a close-up of the controller's connection area, showing the large 9-core motor plug (18.8mm diameter) and the 1T5 cable connection. It confirms the 30A controller's suitability for 1000W motors.
