5. Setup and Installation
Proper installation is crucial for the performance and longevity of the LED driver. Always ensure power is disconnected before beginning installation.
Wiring Connections:
- Input Power: Connect the AC input (120-277V, 50-60Hz) to the designated input terminals (L, N). Ensure correct polarity.
- LED Output: Connect the LED module(s) to the LED output terminals (+, -). Observe correct polarity for the LED load. The output current is settable between 150-1400mA.
- Dimming Control (0-10V): Connect the 0-10V dimming wires to the dedicated dimming terminals. Ensure the dimming control signal is compatible with 0-10V standards.
- LEDcode/NTC: These terminals are for advanced control and temperature sensing. Refer to eldoLED documentation for specific programming and connection details. Note that LEDcode/NTC is not isolated from Class 2 output.

Mounting: The driver is designed for wall mount installation. Ensure adequate ventilation around the unit to prevent overheating.
6. Operating Instructions
Once properly installed and powered, the SOLOdrive 564/S operates automatically. The primary control is through the 0-10V dimming input.
- Dimming: Apply a 0-10V signal to the dimming terminals. A 10V signal will result in 100% light output, while a 0V signal will dim the LEDs to 0.1% (near dark).
- Programming: The SOLOdrive 564/S is programmable. Custom output current, dimming curves, and minimum dimming levels can be configured using eldoLED's programming tools. Contact eldoLED support or your distributor for programming services or tools.
7. Maintenance
The eldoLED SOLOdrive 564/S is designed for long-term, reliable operation with minimal maintenance.
- Cleaning: Ensure the driver is clean and free from dust and debris. Disconnect power before cleaning. Use a dry, soft cloth. Do not use liquid cleaners.
- Inspection: Periodically inspect wiring for any signs of damage or loose connections.
- Ventilation: Ensure that the area around the driver remains clear to allow for proper heat dissipation.
8. Troubleshooting
If you encounter issues with your SOLOdrive 564/S, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No light output | No input power Incorrect wiring Faulty LED module Dimming signal at 0V | Check power supply and circuit breaker Verify all wiring connections (input, output) Test LED module with a known good driver Check 0-10V dimming signal; ensure it's above 0V for light output |
| Flickering or unstable light | Loose connections Incompatible dimmer Overloaded driver | Check all wiring connections Ensure 0-10V dimmer is compatible and functioning correctly Verify LED load does not exceed driver's maximum output power (50W) |
| Driver is hot to touch | Insufficient ventilation Ambient temperature too high Overloaded driver | Ensure proper airflow around the driver Verify ambient operating temperature is within specified range (-20 °C to +50 °C) Check LED load against driver specifications |
If problems persist, contact eldoLED technical support.
