Installation Guide
MAGNETIC DIMMABLE POWER SUPPLY
GENERAL
This power supply is to be installed Indoor / Outdoor in accordance with
Article 450 of the National Electric code (N.E.C.) . The power supply must be
installed in a well-ventilated area free from explosive gases and vapors.
Proper operation requires the free flow of air. Only a qualified electrician
should install this hardwired power supply.
PRECAUTIONS BEFORE INSTALLING
Check the label and ensure the power supply has the proper input voltage,
output voltage and wattage for the job. Check the wire markings to ensure they
match the wiring diagram on this instruction sheet.
LOADING
Recommended 20% to 80% loading for optimal performance. May vary with dimmer
model.
MOUNTING
Select a suitable location capable of supporting the weight of the power
supply. Use the two keyholes provided on the mounting flange.
INPUT CONNECTIONS/GROUNDING
Remove the wiring compartment knockouts and install strain reliefs. With power
turned off, route the input wires through a strain relief and connect white
wire to “N” terminal block and black wire to “L” terminal block. The power
supply case MUST be grounded in accordance with the N.E.C. Connect the “G”
terminal to ground.
OUTPUT CONNECTIONS
Bring the 12 or 24 volt DC LED wires through the open knockout and connect the
positive (+) side to the (+) terminal block, and negative (-) side to the (-)
terminal block.

TROUBLESHOOTING
Prior to troubleshooting, ensure all items are a compatible system and main power is turned ON.
Fixture does not illuminate| • See ‘Wiring Diagrams’ and installation
guides of all components. Ensure the system is wired correctly and polarities
are correct.
• Ensure the power supply and fixture have the same voltage specifications
(12V &12V or 24V & 24V).
---|---
Fixture does not dim| • Ensure a compatible constant voltage dimmable
fixture is installed.
• Ensure a compatible dimming control is installed and wired correctly. See
‘DIMMABLE Compatibility List.’
Different fixture types do not dim in sync| • Different fixture types have
different circuit designs and may react differently when dimmed. Ensure each
fixture type is installed on a separate dimmable power supply for best
performance.
Fixture is quickly flashing or flickering| •Verify a compatible dimming
control is installed.
•Ensure a compatible constant voltage dimmable fixture is installed.
• Ensure all connections are properly secured.
• Ensure fixture is receiving the correct input voltage.
Fixture is slowly flashing| • Ensure power supply is not overloaded. An
overloaded power supply will cause the internal auto-reset to trip repeatedly.
• Check for overload.
Installation Trips Main Breaker| •Check wiring for short circuit. If
breaker continues to trip there may be a short in the power supply. Call
customer support for a replacement power supply.
• Check AFCI for faults.
• Check for neutral or ground faults.
