How to Connect the Battery to the CT-301A9 Controller
Before wiring the CT-301A9 controler, you should know how to connect it to the battery. The controller's voltage rating must match the battery's nominal voltage. Make sure to match the colour of the wires on the plugs and sockets. Then, fix the plugs to the sockets using tape or heat shrinkage tube. Do not invert the positive power line and the black earth wire. Inverting them will cause the controller to malfunction. To connect these two wires, it is recommended that you connect the earth first and then connect the other wires. Only after verifying the wiring properly, connect the positive power line.
Before starting to wire your CT-301A9 controler, you need to know what parts are connected together. You should know which components are wired directly to the speed controller. Make sure you wire the negative battery terminal to the black (negative) wire on the controller. Incorrect connections can damage the components and cause the controller to stop working. Fortunately, this electric scooter controler can be easily fixed and repaired.
The present edition of the CT-301A9 operation manual replaces the previous edition. The following instructions describe how to connect the battery to the CT-301A9 controller. Before connecting the battery, check the rated voltage of the controller and the battery. Match the female terminals of plugs with the same colour wires. Tape or heat shrinkage tube is used to secure the plugs. The positive power line and the black earth wire must never be inverted as it may damage the controller. Always connect the earth wire first and then connect the other wires. Check all wires to make sure they are connected correctly.
