Tips
• For optimal light uniformity in halo-lit applications the Tetra
light output from the Tetra
the sign and will provide simple mounting for the Tetra
• A best practice for the supply wire at the point at which it is brought into the sign is to have a drip loop on the inside of the letter to
keep water from collecting on the Tetra
• These products are not required to be enclosed or protected from weather.

Solution
• Check AC input connection and/or check circuit breaker.
• Check wire connection(s) at the Tetra
termination(s) or short circuits. Properly terminate or replace the wire connection(s).
• Check that connections are the red striped wire (+) of the LED strip to the red wire (+) of
the power supply and the white wire (-) of the LED strip to the black or blue wire (-) of the power supply.
• Ensure the overall length of the Tetra
• Ensure the length of supply wire is equal to or below the recommended remote mounting distance.
• Check wire connection(s) at the Tetra
termination(s) or short circuits. Properly terminate or replace the wire connection(s).
• Check that connections are the red striped wire (+) of the LED strip to the red wire (+) of the
power supply and the white wire (-) of the LED strip to the black or blue wire (-) of the power supply.
• Re-route supply wire and secure to the back of the can with silicone. Adjust wire connector
orientation so that it does not cover any LEDs.
• Adjust LED layout to ensure uniformity of illumination on the face of the letter.
LED system should be directed back into the sign enclosure. This will allow for uniform backlighting of
