and connect to the first module on the strip.
NOTE: Exceeding maximum load will cause the power
supply to shut down. If overload occurs, remove excess
load, recycle the input power to restart the power supply.
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. Using the layout guidelines above, determine required number of LED modules required to illuminate the sign.
6. 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.
®
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.

To Power Supply
Connect the red stripe wire (+) of the LED system to
the red wire (+) of the power supply. Connect the white
wire (-) of the LED system to the black or blue wire (-)
of the power supply.
NOTE: All electrical connections should be suitably
protected from mechanical damage and the
environment. Seal all connections in locations that may
be exposed to water with electrical grade RTV silicone.
