Tips
• Tetra
®
LED systems are rated for damp location use by UL, and should be protected from direct exposure to moisture (i.e., rain & snow).
• For optimal light uniformity in halo-lit applications the Tetra
®
LED modules should be mounted on UL recognized plastic and the light output
from the Tetra
®
LED system should be directed back into the sign enclosure. This will allow for uniform backlighting of the sign and will
provide simple mounting for the Tetra
®
LED system.
• When mounting LED modules for halo-lit applications the clear acrylic should be recessed into the body of the sign or a bead of silicone
should be applied to provide a barrier against the elements.
• 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
®
LED strip.

Troubleshooting
Symptom
Solution
All letters are OFF
• Check AC input connection and/or check circuit breaker.
• Check wire connection(s) at the Tetra
®
LED System and power supply for improper 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.
Some LEDs
appear dim
• Ensure the overall length of the Tetra
®
LED System does not exceed the maximum load.
• Ensure the length of supply wire is equal to or below the recommended remote mounting distance.
Some of the letters
are not illuminated
• Check wire connection(s) at the Tetra
®
LED System and power supply for improper 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.
Shadows
• 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.
