4. Setup and Installation
Installation of this LED power supply should be performed by a qualified electrician in accordance with all applicable electrical codes and standards.
- Power Disconnection: Ensure all power to the installation area is disconnected at the circuit breaker before beginning any work.
- Mounting: Securely mount the power supply in a suitable outdoor enclosure or location, ensuring adequate ventilation and protection from direct water immersion.
- Input Wiring (AC): Connect the AC input wires (Line, Neutral, Ground) from your 347-480V supply to the corresponding terminals on the power supply. Refer to the wiring diagram on the unit label.
- Output Wiring (DC): Connect the DC output wires (+ and -) from the power supply to your LED fixture(s). Observe correct polarity.
- Dimming Control (0-10V): If using 0-10V dimming, connect the dimming control wires to the designated dimming terminals.
- Verification: Double-check all connections for tightness and correct wiring before restoring power.

- The "LED set" feature can automatically configure the output current based on the connected LED module.
- Note: Programming can be performed without connecting the power supply to AC line voltage.
6. Operating Instructions
Once installed and programmed, the power supply operates automatically. Its primary function is to provide a constant current to the connected LED load.
6.1 Dimming Functionality
This power supply supports 0-10V dimming, allowing integration with standard dimmers, sensors, and energy management systems.
- Connect a compatible 0-10V dimmer to the dimming control terminals.
- Adjust the dimmer to control the light output from 10% to 100%.
- Ensure the dimmer is rated for the application and properly installed.
7. Maintenance
The OSRAM OPTOTRONIC LED Power Supply is designed for long-term, reliable operation with minimal maintenance. However, periodic checks can help ensure optimal performance and longevity.
- Cleaning: Periodically inspect the unit for dust or debris accumulation. Clean the exterior with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Connections: Annually, or as needed, inspect all electrical connections for tightness and signs of corrosion. Ensure wiring insulation is intact.
- Environmental Check: Verify that the operating environment remains within specified temperature and humidity ranges. Ensure proper ventilation.
- Professional Inspection: For any internal inspection or repair, contact qualified service personnel.
8. Troubleshooting
If you experience issues with your LED power supply, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| LEDs do not light up. | No input power; incorrect wiring; faulty LED fixture; incorrect programming. | Check circuit breaker and power connections. Verify AC input and DC output wiring polarity. Test LED fixture. Re-program power supply if necessary. |
| LEDs flicker or dim inconsistently. | Loose connections; incompatible dimmer; faulty dimmer; incorrect programming. | Inspect all wiring connections. Ensure dimmer is compatible and functioning correctly. Verify programming settings. |
| Power supply is hot. | Overload; insufficient ventilation; high ambient temperature. | Ensure total LED load does not exceed 180W. Provide adequate airflow around the unit. Relocate if ambient temperature is too high. |
If the problem persists after attempting these solutions, contact customer support or a qualified electrician.
