NOTE: The maximum loading claimed in the table is at ambient temperature 25°C (77°F).
For linear long runs, center connection to the LED strip is recommended to minimize voltage drop.
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.
• Ensure the overall length of the Tetra® LED System does not exceed the maximum load.
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 electrical grade RTV 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.
