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.
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.
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.
