6. Setup and Installation
Proper installation is critical for the safe and efficient operation of your electric bike or scooter. Follow these steps carefully. It is recommended to consult an experienced technician if you are unfamiliar with electrical installations.
- Preparation: Ensure the electric bike/scooter is powered off and the battery is disconnected. Gather necessary tools (screwdrivers, wire cutters, electrical tape, zip ties).
- Mounting the Controller: Find a suitable, protected location on your bike/scooter for the controller. Secure it firmly using appropriate fasteners. Ensure good airflow for heat dissipation.
- Mounting the Display: Attach the SW900 LCD display to your handlebar in a position that is easily visible and accessible. Secure it tightly.
- Wiring Connections: Refer to the wiring diagram (if provided separately, or general e-bike wiring principles) and the labels on the controller's wires. Connect the following components:
- Motor Wires: Connect the three thick phase wires (usually green, blue, yellow) from the controller to the corresponding motor phase wires. Connect the smaller Hall sensor wires (usually five wires: red, black, yellow, green, blue) from the controller to the motor's Hall sensor connector.
- Battery Wires: Connect the thick red wire from the controller to the positive (+) terminal of your battery and the thick black wire to the negative (-) terminal. Ensure correct polarity.
- Display Wire: Connect the SW900 LCD display cable to the designated connector on the controller's wiring harness.
- Throttle: Connect the throttle connector to the controller's throttle input.
- Brake Levers: Connect the brake lever cut-off wires (if applicable) to the controller's brake input connectors.
- PAS Sensor (Pedal Assist System): Connect the PAS sensor wire (if applicable) to the controller's PAS input.
- Other Connections: Connect any other accessories such as lights or speed sensors as per your bike's configuration.
