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.
