Retrofit Instructions
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 Tetra
®
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 Tetra
®
Class 2 Power Supplies required to power the number of LED modules required to illuminate the sign, so as not to overload the
Tetra
®
Class 2 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.
