Safety Information

Please read all safety instructions carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or other hazards.

• Installation should only be performed by a qualified electrician in accordance with local wiring regulations.
• Ensure the power supply is disconnected before commencing any installation, maintenance, or troubleshooting.
• Do not exceed the maximum load of 105W/VA.
• This transformer is equipped with 1.0 Kv Surge Protection for enhanced safety.
• Ensure adequate ventilation around the transformer to prevent overheating.
• The product conforms to EN 61547 Safety Compliance, EN 61347 EMC Conformity, EN 55015, EN 61000, and EN 61547 standards.

Setup and Installation

The AU-RD105 transformer is designed for easy installation and can serve as a replacement for various manufacturers' transformers, including Baon, Y Shin, Huibolong, Eaglerise, Next, and IKEA models.

Installation Steps:

1. Power Disconnection: Before starting, ensure the main power supply to the circuit is switched off at the consumer unit/fuse box.
2. Mounting: Securely mount the transformer in a suitable location, ensuring it has adequate space for ventilation. The transformer has a 10mm hole diameter for mounting.
3. Wiring Input (240V AC): Connect the 240V AC mains input wires to the designated input terminals on the transformer. It is crucial to correctly wire the live and neutral conductors to their respective terminals.
4. Wiring Output (12V AC): Connect the 12V AC output wires from the transformer to your low voltage lighting fixtures. The polarity for the 12V output wires (from transformer to light) is generally not critical and can be wired either way.
5. Secure Connections: Ensure all wire connections are tight and secure to prevent loose contacts and potential hazards.
6. Restore Power: Once all connections are verified and secure, restore power to the circuit.

Note: If replacing an existing transformer, carefully note the wiring configuration of the old unit before removal.

Operating Instructions

The AURORA AU-RD105 transformer operates automatically once correctly installed and powered. It converts the 240V AC input to a stable 12V AC output for your low voltage lighting.

• Dimmable Functionality: This transformer is fully dimmable and compatible with both resistive and inductive dimmer switches. Ensure your dimmer switch is rated appropriately for the total wattage of your connected lighting.
• Load Management: Ensure the total wattage of the connected 12V lamps does not exceed the transformer's maximum rating of 105W/VA. Operating below the minimum load (typically 35W for this model) may affect dimming performance or cause flickering.

Maintenance

The AURORA AU-RD105 Electronic Transformer is designed for long-term, maintenance-free operation.

• Cleaning: If necessary, gently wipe the exterior of the transformer with a dry, soft cloth. Do not use liquid cleaners or solvents. Ensure power is disconnected before cleaning.
• Ventilation: Periodically check that the ventilation slots are not obstructed by dust or debris to ensure proper heat dissipation.
• Inspection: Occasionally inspect the wiring connections for any signs of loosening or damage. Address any issues promptly by disconnecting power and re-securing connections.
