FOR UL ONLY

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.

Save These Instructions
Use only in the manner intended by the manufacturer.
If you have any questions, contact the manufacturer.

WARNING

RISK OF ELECTRIC SHOCK

• Disconnect power at fuse box or circuit breaker before servicing or installing product.
• Properly ground Tetra® power supply.
• AC input connections shall be suitably enclosed. The power supply shall be enclosed or made inaccessible to users during normal use.

RISK OF FIRE

• Minimum power supply spacing to other power supply or other heat producing component shall be at least 4” (101.6 mm) from side to side and 1” (25.4mm) from end to end.
• 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.

CAUTION

RISK INJURY

• While performing installations described, gloves, safety glasses or goggles should be worn.

Power Supply Installation

1. Mount 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.
   

2. Connect the AC line to the black or brown (line) and white or blue (neutral) input wires of the power supply using suitable wire connectors.
   
   WARNING
   RISK OF ELECTRIC SHOCK
   AC input connections shall be suitably enclosed. Optionally, the GEPSJB60 may be used for this purpose

3. 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 specific module loading guides.

FOR UL   ONLY
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.
FOR UL ONLY
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.

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.

Troubleshooting

• The GEPS24-100U-TT features a new built in output overload shutdown feature that automatically resets when the AC supply is removed and reapplied. So if all letters are off, first verify whether or not the output can be reset by first switching off then switching back on the AC supply. If the letters do not re-light, then proceed to the following solutions.
• Check AC input connection and/or check circuit breaker
• Check wire connection(s) at the Tetra® LED System and power supply for improper termination(s) or short circuits. Properly terminate or replace the wire connection(s).
• Check that connections are the red striped wire (+) of the LED strip to the red wire (+) of the power supply and the white wire (-) of the LED strip to the black or blue wire (-) of the power supply.
• Ensure the overall length of the Tetra® LED System does not exceed the maximum load. If so, remove the excess load and cycle the AC supply to reset the drivers built in overload protection.

Some LEDs appear dim|

• Ensure the length of supply wire is equal to or below the recommended remote mounting distance.

Some of the LEDs are not illuminated|

• Check wire connection(s) at the Tetra® LED System and power supply for improper termination(s) or short circuits. Properly terminate or replace the wire connection(s).
• Check that connections are the red striped wire (+) of the LED strip to the red wire (+) of the power supply and the white wire (-) of the LED strip to the black or blue wire (-) of the power supply
