  • Short Circuit & Overload Protected
  • Class 2 rated
  • Compact design (approximately 4 x 2 x 1.5 inches)

Setup and Installation

Before beginning installation, ensure all power to the circuit is turned off at the main breaker. Incorrect wiring can lead to electrical shock or fire.

  1. Disconnect Power: Locate the circuit breaker controlling the lighting fixture and switch it to the OFF position. Verify power is off using a voltage tester.
  2. Identify Wiring: The transformer has two sets of wires:
    • Primary (Input) Wires: These connect to your 120V AC power supply. Typically, these are black (hot) and white (neutral).
    • Secondary (Output) Wires: These connect to your 12V halogen lamp(s).
  3. Connect Primary Wires: Connect the 120V AC input wires from your power source to the transformer's primary wires. Use appropriate wire connectors (e.g., wire nuts) and ensure secure connections.
    • Connect the Hot (Live) wire from the power source to the transformer's Hot (Live) input wire.
    • Connect the Neutral wire from the power source to the transformer's Neutral input wire.
  4. Connect Secondary Wires: Connect the transformer's 12V output wires to your halogen lamp fixture. Ensure the total wattage of all connected lamps does not exceed 80W.
  5. Secure Transformer: Mount the transformer in a suitable, well-ventilated location, away from direct heat sources or moisture. Ensure it is securely fastened to prevent movement.
  6. Restore Power: Once all connections are secure and the transformer is mounted, restore power at the circuit breaker.

Operating Instructions

The Cal TR-60 Electronic Transformer operates automatically once properly installed and powered. It requires no user interaction for its primary function.

  • Power On: After installation, turn on the power at the circuit breaker and then activate the light switch connected to the fixture.
  • Lamp Operation: The transformer will supply the necessary 12V AC power to the connected halogen lamps, allowing them to illuminate.
  • Dimming: If using with a dimmer switch, ensure the dimmer is compatible with electronic low-voltage transformers and halogen loads. Incompatible dimmers can cause flickering or damage to the transformer/lamps.

Maintenance

The Cal TR-60 Electronic Transformer is designed for maintenance-free operation. However, periodic checks can help ensure longevity and safety.

  • Cleaning: Ensure the transformer remains free of dust and debris. If cleaning is necessary, disconnect power and wipe with a dry, soft cloth. Do not use liquid cleaners.
  • Ventilation: Periodically check that the area around the transformer remains clear and well-ventilated.
  • Wiring Inspection: Annually, or if issues arise, inspect wiring connections for any signs of loosening, corrosion, or damage. Disconnect power before inspection.
  • Lamp Replacement: When replacing halogen lamps, ensure the new lamps do not exceed the transformer's 80W maximum output.

Troubleshooting

Problem Possible Cause Solution
Lamps do not light up.
  • No power to the transformer.
  • Loose wiring connections.
  • Faulty lamp(s).
  • Transformer overload protection activated.
  • Faulty transformer.
  • Check circuit breaker and light switch.
  • Turn off power, check all wiring connections.
  • Test lamps in another fixture or replace.
  • Reduce total wattage of connected lamps. Disconnect power, wait a few minutes, then restore.
  • If all else fails, the transformer may need replacement.
Lamps flicker or dim inconsistently.
  • Incompatible dimmer switch.
  • Loose connections.
  • Transformer operating near maximum load.
  • Ensure dimmer is rated for electronic low-voltage transformers.
  • Turn off power, check all wiring connections.
  • Reduce total wattage of connected lamps.
Transformer makes humming noise.
  • Normal operation (slight hum).
  • Overload or faulty lamp.
  • A slight hum is normal for some electronic transformers.
  • Check total wattage of lamps. Replace any faulty lamps.
