1. (Existing Signs Only) Prior to installation, survey the site for information regarding power and accessibility inside and outside the building. Ensure that the
branch circuit supplying the existing transformer or ballast will be within the voltage ratings of the new LED power supply, and have a current rating
not exceeding 20A, or that permitted by applicable local, state, or country electrical codes (whichever is less).
2. (Existing Signs Only) Remove the existing lighting equipment to be replaced, such as neon tubing or fluorescent tubes; and associated transformers and
ballasts. Care should be taken not to break the existing neon or fluorescent tubes.
NOTE:
Follow all federal and local regulations when disposing of neon tubing, fluorescent tubes, transformers and ballasts.
3. (Existing Signs Only) If removal of the existing lighting equipment eliminates the disconnect switch, as required by applicable local, state, or country electrical
codes; a new disconnect switch must be installed.
4. (Existing Signs Only) Make sure the removal of lighting equipment does not compromise the integrity of the sign body (i.e. water intrusion). Fill in all holes
0.5 in. (13 mm) or smaller with the appropriate amount of rated caulk or sealant. For holes greater than 0.5 in. (13 mm), use an aluminum or zinc coated steel
patch with rivets and sealant.
5. Determine the necessary footage of Contour to illuminate sign.
6. A Tetra
®
24VDC Class 2 Power Supply, as listed below, must be used with this retrofit kit. Determine the number of Tetra
®
Class 2 Power Supplies required to
power the footage of Contour required to illuminate the sign using the loading chart below, so as not to overload the Tetra
®
Class 2 Power Supply chosen.
7. Follow the instructions above to properly mount the LED modules.
8. Connect the DC output of the power supply to the LED modules using the Electrical Connections instructions above.
9. Connect the power unit to the supply in accordance with the applicable local, state, and country electrical codes, and the instructions found in the power
supply installation guide.
10. If required, the disconnect switch shall be installed by qualified personnel, in accordance with applicable local, state, and country electrical codes.

Symptom
Solution
All LEDs are OFF
Check AC input connection and/or check circuit breaker
Check wire connection(s) at the Tetra Contour LS section and power supply for improper termination(s) or
short circuits. Properly terminate or replace the wire connection(s).
Check that connections are the white wire with red stripe (+) 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 Contour LS does not exceed the maximum load.
Ensure the length of supply wire is equal to or below the recommended remote mounting distance.
Make sure that all LED light engines have the same suffix code (suffix code is located on the box label).
Some of the sections are not illuminated
Check wire connection(s) at the Tetra Contour LS section and power supply for improper termination(s) or short
circuits. Properly terminate or replace the wire connection(s).
Check that connections are the white wire with red stripe (+) 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.
