3. Driver Selection: Use compatible OSRAM Optotronic OTe, OT Fit, or OTi DALI ballasts for optimal performance. The system is designed for flexibility in driver selection.
4. Thermal Management: Ensure adequate cooling for the module. Its optimized efficiency and high operating temperature range aid in thermal management, but proper heat sinking is crucial for longevity.
5. Multiple Modules: For installations requiring multiple modules, utilize the flexible connection possibilities (parallel, series, or mixed circuits) as appropriate for your system design.

Always consult local electrical codes and safety regulations during installation. Installation should be performed by a qualified professional.

4. Operating Instructions

Once installed, the OSRAM PrevaLED Core Z4 LED module operates by receiving power from a compatible LED driver (ballast).

• Power On/Off: Control the module's operation via the connected LED driver or the main power supply to the lighting fixture.
• Current Adjustment: The control board allows for easy current adjustment within a range of 0.1 A to 5 A, depending on the system configuration and load. Refer to your driver's manual for specific adjustment procedures.
• Dimming: If using an OTi DALI driver, the module supports dimming functionalities. Consult the OTi DALI driver's documentation for dimming setup and operation.

5. Maintenance

The OSRAM PrevaLED Core Z4 LED module is designed for long-term, low-maintenance operation. However, some considerations can help ensure its longevity:

• Cleaning: Ensure the module remains free from dust and debris. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
• Thermal Management: Regularly check that the module's operating environment allows for proper heat dissipation. Blocked ventilation or excessive ambient temperatures can reduce lifespan.
• Connection Integrity: Periodically inspect wiring connections to ensure they remain secure, especially in environments subject to vibration.

Do not attempt to open or modify the LED module, as this may void the warranty and could lead to product damage or electrical hazards.

6. Troubleshooting

If you encounter issues with your PrevaLED Core Z4 LED module, consider the following:

• Module Not Illuminating:
  • Check the power supply to the LED driver.
  • Verify all wiring connections for correct polarity and secure contact.
  • Ensure the LED driver is compatible and functioning correctly.
• Intermittent Operation or Dimming:
  • The module features a reversible thermal shutdown. If the module overheats, it will temporarily shut down or reduce output. Allow it to cool down and check for proper ventilation.
  • If using an OTi DALI driver, thermal throttling may occur. Consult the driver's manual.
  • Check for loose connections or faulty wiring.
• Reduced Brightness:
  • Confirm the LED driver is supplying the correct current.
  • Ensure the module is not operating in an excessively hot environment, which can trigger thermal protection.

If problems persist after checking these points, contact a qualified electrician or OSRAM customer support for assistance.
