5.3 Wiring Instructions

  1. Input Wiring (AC Side):
    • Connect the Black (AC L) wire from the driver to the Live/Hot wire from your AC power source (or dimmer output).
    • Connect the White (AC N) wire from the driver to the Neutral wire from your AC power source.
    • Connect the Green (Ground) wire from the driver to the Earth Ground wire.
  2. Output Wiring (DC Side):
    • Connect the Red (LED +) wire from the driver to the positive (+) input of your 24V DC LED light fixture.
    • Connect the Black (LED -) wire from the driver to the negative (-) input of your 24V DC LED light fixture.
  3. Ensure all connections are secure and insulated. Use appropriate wire nuts or connectors.

5.4 Mounting

  • Mount the driver securely using the integrated mounting tabs.
  • Ensure the mounting surface is stable and can support the weight of the driver.
  • Allow for adequate air circulation around the driver to prevent overheating. Do not enclose in a sealed, unventilated space.

6. Operating Instructions

Once the driver is correctly installed and wired, restore power at the circuit breaker.

  • The connected LED lights should illuminate.
  • Use your compatible AC wall dimmer to adjust the brightness of the LED lights.
  • For optimal dimming performance and to avoid potential buzzing or flickering, ensure the total load of your LED fixtures is at least 10% of the driver's maximum capacity (300W * 10% = 30W).
  • The driver is designed for smooth dimming across its range.

7. Maintenance

  • The LEDUPDATES Dimmable LED Driver is designed for maintenance-free operation.
  • Periodically inspect the wiring connections to ensure they remain secure.
  • Keep the driver free from dust and debris to ensure proper heat dissipation. Clean with a dry, soft cloth if necessary.
  • Do not use liquid cleaners or solvents.
  • Ensure the operating environment remains within the specified temperature and humidity ranges.
