How to Install ES LD040D-CU09542-M28F Dimming Constant Current LED Driver?

1. Turn off the power: Before installing the LED driver, make sure to turn off the power to the circuit from the circuit breaker or the main electrical panel.

2. Choose the installation location: Select a suitable location to mount the driver. The location should be dry and free from any heat sources.

3. Mount the driver: Use screws to mount the driver on a solid surface.

4. Connect the input wires: Connect the input wires from the driver to the AC power source. Make sure to match the correct wires (hot and neutral) from the driver to the corresponding wires from the power source. (White color wire to Neutral (N) and the Black color Wire to Line (L))

5. Connect the output wires: Connect the output wires from the driver to the LED lighting fixture. Make sure to match the correct wires (positive and negative) from the driver to the corresponding wires from the fixture. ( Red color wire to the positive (+) and Black wire to the negative (-))

6. Test the installation: Once the connections are made, turn on the power to the circuit and test the LED fixture to ensure it is working properly.

7. Adjust dimming settings: If the driver is dimmable, follow the manufacturer's instructions to connect the dimming wires and adjust the dimming settings as required.

Note: It's important to follow the specific instructions provided by the manufacturer for your LED driver, as installation procedures may vary based on the model and manufacturer. If you are not comfortable with electrical installations, it is recommended to consult a licensed electrician for assistance.
