3. Installation Instructions

3.1. Before You Begin

1. Turn off power at the circuit breaker or fuse panel.
2. Remove the existing wall plate and switch/dimmer.
3. Verify the wiring configuration in your wall box. This dimmer is designed for single-pole applications.
4. Ensure the load (LED drivers or fluorescent ballasts) is compatible with 0-10V dimming and the dimmer's specifications (120/277V, 8A max).

3.2. Wiring

The NTSTV-DV-WH dimmer typically has two black wires for line/load connections and two low-voltage wires (often purple and gray/pink) for 0-10V control. The black line and load wires are interchangeable; either can be connected to the incoming power (line) and the other to the fixture (load). The 0-10V control wires are typically marked for polarity (e.g., '+' and '-').

• Connect one black dimmer wire to the incoming hot wire from the circuit breaker.
• Connect the other black dimmer wire to the load wire leading to the lighting fixture.
• Connect the ground wire from the wall box to the dimmer's ground screw (if present) or splice with the dimmer's ground wire.
• Connect the 0-10V control wires from the dimmer to the corresponding 0-10V control wires on the compatible LED driver or fluorescent ballast, observing polarity.
• For loads exceeding 8 amps, a Lutron PP-20 power pack is required and must be wired according to its separate instructions.

3.3. Mounting

1. Carefully fold wires into the wall box, ensuring no wires are pinched.
2. Secure the dimmer to the wall box using the provided screws.
3. Attach the wall plate.
4. Restore power at the circuit breaker.

4. Operating Your Dimmer

4.1. Light Level Adjustment

To adjust the light level, simply slide the control lever up or down. Sliding the lever upwards increases the light intensity, while sliding it downwards decreases the intensity. Sliding the lever all the way down will turn the lights off.

4.2. Fine-Tuning (Trim Adjustment)

The NTSTV-DV-WH dimmer includes adjustable high-end and low-end trim screws located behind the cover plate. These allow for fine-tuning the maximum and minimum light output to optimize performance with your specific lighting fixtures.

• Remove the wall plate to access the trim screws.
• Use a small screwdriver to adjust the screws.
• Adjust the high-end trim to prevent flickering at maximum brightness.
• Adjust the low-end trim to ensure stable dimming at the lowest desired light level without the lights turning off prematurely.
• Replace the wall plate once adjustments are complete.

5. Maintenance

The Lutron NTSTV-DV-WH dimmer requires minimal maintenance.

• To clean the dimmer, wipe with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Ensure the dimmer and wall plate are free from dust and debris to maintain proper operation and appearance.
• Periodically check for any loose connections or signs of wear, especially during other electrical maintenance.
