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.
