Wiring Diagram
The orange Boost Tap is an optional voltage boost recommended for use with a MLV dimmer, as most MLV dimmers cut down voltage by 10%.
Additionally, if the fixture is receiving 10.5V or less in an ON/OFF switch installation, the orange Boost Tap is recommended.

Lights are non functional.
Make sure 120V AC Breaker is in the ON position
Use a multimeter to check DC output voltage at the lighting source.
If lights remain unresponsive, confirm the following:
• Wire polarity
• Accessories and accessory placement.
Lights are not dimming or flickering.
1. Confirm a compatible 120V MLV dimmer switch has been installed
between the AC line voltage and dimmable driver. Visit the online
page for this product for a detailed list of compatible dimmers.
2. Check that the 12V DC light fixture installed is rated as a dimmable
LED Fixture.
