Layout Modules

1. Before you begin, clean surfaces and remove all debris from the inside of the channel letter. Clean the surfaces with a 50:50 mixture of isopropyl alcohol (IPA) and water and let dry.
2. Measure and cut Tetra LED strip to the appropriate length for each letter. Cuts can be made between any of the modules.
3. Remove tape backing and stick LED modules into place. When using tape apply approximately 15 psi pressure on the module (avoid the lens dome surface) for 5 seconds, full bonding strength after 24 hours. Continue until you have reached the end of the strip.
4. Use rivets, screws, or electrical grade RTV silicone to secure at least every fifth LED module within the channel letter. Use #6 (M3) pan headed metal screws, 1/8-inch (3.2 mm) rivets, or electrical grade RTV silicone. NOTE: Modules may be damaged by improperly sized screws or over-torquing
5. Drill a 1/4-inch (6.4 mm) hole near the LED strip and grommet the hole for supply wire access.
6. Remove all the debris from the inside of the channel letter and replace the sign face. NOTE: For halo-lit applications LED modules should be mounted on UL recognized clear acrylic or poly carbonate. The light output from the LED system should be directed back into the sign enclosure. This will allow for uniform backlighting of the sign and will provide simple mounting.

Electrical Connections

NOTE: Do not use connectors pre-filled with silicone grease/mineral base protective grease or use silicone grease to seal connections.

1. Connect LED strips using in-line (IDC) connectors or twist-on wire connectors.
   NOTE: Seal all connections in wet locations with electrical grade RTV silicone.

2. Must cap all exposed wires with appropriate wire connectors and seal with electrical grade RTV silicone.
   Optional: Cut wires flush to the module and seal with electrical grade RTV silicone.

3. Run a wire from the LED power supply to the LED module and connect.
   NOTE: Must be used with a 24 Volt Power Supply.
   NOTE: Refer to Maximum Loading & Remote Mounting Specifications on last page.

4. Connect the red stripe wire (+) of the LED strip to the red wire (+) of the power supply. Connect the white wire (-) of the LED strip to the black or blue wire (-) of the LED power supply.
   NOTE: All electrical connections should be suitably protected from mechanical damage and the environment. Seal all connections in wet locations with electrical grade RTV silicone.

OPTIONAL
A Weather Box (GEXNWB2) may be used to house and seal Class 2 connections.
A) Insert wire connectors into weather box. Fill with electrical grade silicone and close box.
B) Secure the weather box using a #6 or #8 (M2 or M3) screw.

Retrofit Instructions

FOR UL ONLY

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) Repair and seal any unused openings in the electrical enclosure. Openings greater than 12.7-mm (1/2-in) diameter require a metal patch secured by screws or rivets and caulked with non-hardening caulk. Smaller openings may be sealed with non hardening caulk.

5. (Existing Signs Only) A clean and dry mounting surface ensures optimum adhesion if the self-adhesive method of mounting is chosen. Follow the manufacturer’s directions when using a non-oil based solvent, such as rubbing alcohol to clean the surface area where you intend to mount the module. Before installing, ensure the surface is dry.

6. Using the layout guidelines above, determine required number of LED modules required to illuminate the sign.

7. A 24VDC Class 2 Power Supply, as listed below, must be used with this retrofit kit. Using the Maximum Loading chart below, determine the number of Power Supplies required to power the number of LED modules required to illuminate the sign, so as not to overload the Power Supply chosen.

8. Follow the instructions above to properly mount the LED modules.

9. Connect the DC output of the power supply to the LED modules using the Electrical Connections instructions above.

10. 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.

11. If required, the disconnect switch shall be installed by qualified personnel, in accordance with applicable local, state, and country electrical codes.

Troubleshooting

• 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.

Tips

• 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.
• 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.

Dismantling

• At the end of life, the contained LED light source may be cut out using suitable wire cutters, removed from the mounting surface, then replaced per the cutting and installation instructions above, or dismantled and taken to a communal collecting point for environmentally friendly disposal in accordance with local regulations by a professional installer.
