BEFORE YOU BEGIN
Read these instructions completely and carefully.
WARNING/AVERTISSEMENT
RISK OF ELECTRIC SHOCK
• Disconnect power at fuse box or circuit breaker before servicing
or installing product.
• Properly ground Tetra®power supply.
• Must be enclosed in an end product.
RISK OF FIRE
• In the end product, power supply spacing to other heat
producing components shall be minimum 2 inches spacing to
sidewalls and minimum 2 inches spacing to top of enclosure.
• Adjacent power supplies shall be spaced at least 1 in. end to
end and 4 in. in any other direction.
• Use only approved wire for input/output connection. Minimum
size 18 AWG (0.82 mm2).
• Follow all local codes.
• Application considerations potentially requiring additional
spacing include high ambient temperature seen by the
power supply, poor contact with a heat dissipating material,
inadequate ventilation, or direct exposure to sun.
RISQUES DE DÉCHARGES ÉLECTRIQUES
• Coupez l’alimentation électrique à la boîte de fusibles ou au disjoncteur avant
l’entretien ou l’installation du produit.
• Assurez-vous de correctement mettre à terre le bloc d’alimentation Tetra®.
• Doit être inclus à l’intérieur d’un produit nal.
RISQUES D’INCENDIE
• Dans le produit ni, l’espacement entre le bloc d’alimentation et les autres
composants dégageant de la chaleur doit être d’au moins 2 pouces des
parois latérales et d’au moins 2 pouces du haut de l’enceinte.
• Les blocs d’alimentation adjacents doivent être espacés d’au moins 1 po
de bout en bout et 4 po dans toute autre direction.
• N’utilisez que des ls approuvés pour les entrées/sorties de connexion.
Taille minimum 18 AWG (0.82 mm2).
• Respectez tous les codes locaux..
• Certaines applications pourraient requérir un espacement additionnel, p.
ex. une température ambiante élevée autour du bloc d’alimentation, un
mauvais contact avec une matière dissipatrice de chaleur, une ventilation
inadéquate ou une exposition directe au soleil.
Save These Instructions
Use only in the manner intended by the manufacturer.

Prepare Electrical Wiring
Electrical Requirements
• Limited to use in dry and damp locations.
• The suitability of rain enclosure shall be determined if
intended for wet location.
• The grounding and bonding of the LED Driver shall be
done in accordance with National Electric Code (NEC)
Article 600.
• Follow all National Electric Codes (NEC) and local codes.

Power Supply Installation
NOTE: For installation in Canada, a disconnect switch of appropriate rating needs to be placed within 29.5 feet (9 meters) of primary
side of the power supply. The switch voltage rating shall not be less than the branch circuit voltage. The switch must also support
twice the amount of input current.
NOTE: When installing power supply, connect to the appropriate sized building breaker or disconnect device for line, neutral and
ground connections, in accordance with National Electric Code (NEC) Article 600 and all local regulations.
2Connect the AC line to the black
or brown (line) and white or
blue (neutral) input wires of the
power supply using suitable wire
connectors.
Connect the supply wire that is
attached to the Tetra LED System to
the red (+) and black or blue (-) output
wires of the power supply as outlined
in the “Electrical Connections”
section of your LED system’s
Installation Instructions.
NOTE: To avoid overloading this
power supply with LED modules,
please refer to the specic module
loading guides.

1Mount the power supply. Mounting
the power supply base directly to
a thermally conductive installation
surface can improve thermal
performance.
NOTE: All electrical connections
should be suitably protected from
mechanical damage and the
environment. Seal all connections
exposed to water with electrical
grade self-hardening silicone.
WARNING
RISK OF ELECTRIC SHOCK
AC input connections shall be
suitably enclosed.
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.

Symptom Solution
All letters are OFF • Recycle AC power, turn it off, then turn on again.
• If still off, check the power supply DC output voltage using a voltmeter. It should be nominally V.
»If there is DC output, inspect and correct all DC wire damage/polarity issues; If no issue is found, replace the
OFF-module string.
»If there is no DC output, have a licensed electrician check the input AC voltage and if there is correct AC voltage,
replace the power supply.
»If there is no AC voltage, correct the upstream AC issue.
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.
Some of the letters
are not illuminated
• Inspect and correct the wires of the non-illuminated letters for damage/polarity issues; If no issues are found, see the
troubleshooting solution for “All letters are OFF.”
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 of the face of the letter.
