Wiring 0-10V dimmable LED high bay lights requires two separate circuits: the AC power circuit (line/neutral/ground) and the low-voltage 0-10V control circuit. Run standard AC wiring to each fixture as normal. Then run a separate 2-conductor control wire (typically 18AWG, class 2) from the dimmer/controller to each fixture, connecting the (+) and (-) terminals. Polarity matters: the dimmer's (+) must connect to the fixture's (+), and (-) to (-). All fixtures in the same dimming group share the same control signal in parallel. You can daisy-chain the control wire from fixture to fixture. Keep control wires separate from AC power wires (at least 6 inches apart) to avoid interference. The 0-10V signal can typically run up to 300 feet. Always turn off power before wiring, and consult a licensed electrician for commercial installations.
