Power Supply Installation
Connect the supply wire that is
attached to your LED system to the red
(+) and black (-) output wires of the
LED driver as outlined in the “Electrical
Connections” section of your LED
system’s Installation Instructions.
Remove the junction box cover and
carefully remove knockout for AC line
input wires. Install appropriate electrical
fittings in the knockout holes for wire
protection. Securely mount the power
supply with the base in contact with the
mounting surface in accordance with
the power supply spacing requirements
described above. If used in a wet
location, the power supply and electrical
connections shall be protected from
weather by a suitable rain enclosure, and
not subject to saturation with water or
other liquids. If not protected from the
weather, the output connections may be
sealed with electrical grade silicone.
Connect the AC line to the black
(line) and white (neutral) input
wires of the LED driver using
18-14 AWG (0.82-2.08 mm
2
) twist-on
wire connectors. Ground LED driver
by connecting green wire with yellow
stripe to grounding screw. Replace
junction box cover.

NOTE: To avoid overloading this
power supply with LED modules,
please refer to the specific module
loading guides.
FOR UL ONLY
NOTE: For CSA approval, a disconnect/toggle switch of appropriate rating needs to be placed within 29.5 ft. (9 m) of primary
side of the power supply. The minimum rating of the switch must be either 120 or 220 Volts AC. The switch must also support
twice the amount of input current.
FOR UL ONLY
NOTE: When installing power supply, connect to the appropriate sized building breaker or disconnect device for line and
neutral connections, in accordance with local, state or country regulations.
FOR UL ONLY
NOTE: The grounding and bonding of the power supply and overall sign shall be done in accordance with National Electric
Code (NEC) Article 600.
WARNING / AVERTISSEMENT
RISK OF ELECTRIC SHOCK
• Disconnect power at fuse box or circuit breaker before servicing or
installing product.
• Properly ground Tetra
®
power supply.
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 mm
2
).
• 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
®
.
RISQUES D’INCENDIE
• Dans le produit fini, 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 fils approuvés pour les entrées/sorties de connexion.
Taille minimum 18 AWG (0.82 mm
2
).
• 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.
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.
