Setup and Installation
The Portfolio landscape lighting transformer is designed for easy installation. Follow these steps for proper setup:
1. Choose a Mounting Location
Select a suitable outdoor location for wall mounting. The transformer should be mounted vertically at least 1 foot above ground level to prevent water damage, and in an area that allows for proper ventilation. Ensure the location is within reach of a grounded 120V AC outdoor outlet.

Image Description: A black Portfolio landscape lighting transformer is securely mounted on the light gray siding of a house. To its right, a clear, weatherproof electrical outlet cover is visible, with a black power cord extending from the transformer to the outlet. Green bushes flank both sides of the installation, and a concrete path runs in front of it, indicating an outdoor setting.
2. Mount the Transformer
Securely mount the transformer to a sturdy surface using appropriate screws (not included) through the mounting holes on the unit. Ensure it is level and firmly attached.
3. Connect Low-Voltage Cables
This transformer features 2 terminal connections for flexible wiring applications. Connect your 12-volt landscape lighting cables (12, 14, or 16 gauge) to the low-voltage terminals on the transformer. Ensure polarity is correct (positive to positive, negative to negative) and all connections are tight and secure. If using multiple lighting runs, distribute the load evenly across the terminals.
4. Connect to Power
Plug the transformer's power cord into a grounded 120V AC outdoor outlet. For added protection, it is recommended to use a GFCI (Ground Fault Circuit Interrupter) protected outlet.
Operating Instructions
The built-in digital display and timer make operating your Portfolio transformer simple and easy.
Digital Timer Settings
Refer to the digital display and control buttons on the transformer for setting the timer. Common timer modes include:
- ON: Lights remain on continuously.
- OFF: Lights remain off.
- AUTO/Dusk-to-Dawn: The integrated dusk-to-dawn sensor automatically turns lights on at dusk and off at dawn. If your model includes a 15-ft fiber optic tether, ensure the sensor end of the tether is placed in an area that receives ambient light to accurately detect dusk and dawn.
- Timed ON: Lights turn on at dusk and stay on for a set number of hours (e.g., 4, 6, 8 hours). Use the digital display to select the desired duration.
Consult the on-screen prompts or specific button labels on your unit for detailed programming steps.
Manual Override
Most digital timers include a manual override button that allows you to temporarily turn the lights on or off, regardless of the programmed setting. Pressing this button typically cycles through the ON/OFF states.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your landscape lighting transformer.
- Keep Clean: Periodically wipe down the exterior of the transformer with a damp cloth to remove dirt, dust, and debris. Ensure the digital display and sensor (if applicable) are clear.
- Check Connections: Annually inspect all low-voltage cable connections for corrosion or looseness. Tighten as necessary.
- Inspect Cables: Check landscape lighting cables for any signs of damage, cuts, or fraying. Repair or replace damaged sections immediately.
- Ventilation: Ensure the area around the transformer remains clear of obstructions (e.g., overgrown plants) to allow for proper airflow and prevent overheating.
- Winterization: In areas with harsh winters, consider unplugging the transformer and storing it indoors during extreme cold or heavy snowfall to protect it from environmental damage.
