4. Secondary Connection: Connect your 24V DC LED lighting fixtures to the 12-socket distributor. Ensure the total wattage of all connected LED fixtures does not exceed 30W. The maximum permissible length for secondary cables is 5 meters.
5. Verification: Double-check all connections to ensure they are secure and correct.
6. Power On: Restore power at the circuit breaker. The connected LED lights should illuminate.

Note: For optimal dimming performance, use recommended phase-cut dimmers such as Busch-Jaeger 6523U, Sygonix 33594C, or Jung 225TDE.

5. Operating Instructions

Once installed and powered, the Hera 20604001222 LED transformer will provide a stable 24V DC output to your connected LED lights.

• Switching On/Off: Control the power to the transformer via the wall switch or the power outlet it is connected to.
