NOTE:
For installation in Canada, a disconnect switch of appropriate rating needs to be placed within 29.5 ft. (9 m) 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.
NOTE:
Exceeding maximum load per bank will cause the LEDs to dim or blink. Once the excess load is removed, cycle the input power
to restart the power supply.
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)
NOTE:
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) Make sure the removal of lighting equipment does not compromise the integrity of the sign body (i.e. water
intrusion). Fill in all holes 0.5 in. (13 mm) or smaller with the appropriate amount of rated caulk or sealant. For holes greater than
0.5 in. (13 mm), use an aluminum or zinc coated steel patch with rivets and sealant.
5. Using the layout guidelines within the LED module installation instructions, determine required number of LED modules required to
illuminate the sign.
6. Using the applicable LED module maximum Loading chart, 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 any single power supply output.
7. Follow the LED module instructions to properly mount the LED modules.
8. Connect the DC output of the power supply to the LED modules using the Power Supply Installation instructions above.
9. Connect AC power to the power supply in accordance with the applicable local, state, and country electrical codes, and the Power
Supply Installation instructions above.

electrical codes.
Connect the supply wire that is
attached to the Tetra LED System to
the red (+) and black (-) output wires
of the power supply as outlined in
the “Electrical Connections” section
of your LED system’s Installation
Instructions.
NOTE:
Three 96 watt output
banks per power supply. Do not
interconnect output terminations.

Mount power supply and remove
junction box cover. Carefully
remove knockout for AC line input
wires. Install appropriate electrical
wire protection.
Connect the AC line to the black (line)
and white (neutral) input wires of
the power supply and connect the
branch circuit ground to the green
wire with a yellow stripe (ground) wire
using appropriately sized twist-on
wire connectors.
