Complete Lutron DV 600P Wiring Diagram Guide for Installation
For reliable operation, connect the neutral wire directly to the designated terminal–this is non-negotiable. Failure to do so will result in flickering, inconsistent dimming, or complete device failure. The black (hot) wire must be secured to the line terminal, while the red (load) wire attaches to the dimmer output. Double-check that the circuit breaker is off before proceeding; live wires at 120V pose serious shock hazards.
Ground the switch by fastening the bare copper or green wire to the grounding screw. Omitting this step violates electrical codes and increases fire risk. If the wall box lacks a ground, install an insulated grounding pigtail connected to the metal box–never leave it floating. Verify connections with a multimeter: between line and neutral (≈120V), line and ground (≈120V), and load and ground (0V when off).
Use 14 AWG copper wire for branch circuits (15A) and 12 AWG for 20A circuits–incorrect gauge melts insulation and causes shorts. Strip wires to 5/8″ (15.8mm) of exposed conductor; insufficient length weakens contact, while excess risks shorting adjacent terminals. Twist stranded wires clockwise before inserting into screw terminals to prevent stray strands from causing arc faults.
Test the dimmer in three phases:
- Turn power on–verify LEDs illuminate (no flicker).
- Adjust brightness from min to max–check for smooth transitions.
- Load-test with the intended bulb type (LED/CFL/incandescent). Mismatched wattage (below 40W or above 600W) triggers overheating.
Program the device using the air-gap switch: hold for 10 seconds to reset, then tap to set fade rates (default: 3 seconds on/off).
Guide to Installing the DV-Series 600VA Phase-Adaptive Dimmer
Connect the dimmer’s input terminals to the line wire (black) and neutral (white) from the mains, ensuring polarity matches the circuit breaker’s 120V or 277V rating. Verify compatibility with LED, incandescent, or halogen loads by cross-referencing the fixture’s wattage against the dimmer’s 600VA capacity–overloading risks thermal shutdown. For three-way setups, attach the traveler wire (red) to the corresponding terminal on both dimmer and remote switch, leaving the common wire (black) for the hot lead.
Terminal Configuration and Load Types
| Load Type | Minimum Wattage | Maximum Wattage | Wiring Notes |
|---|---|---|---|
| Incandescent | 40W | 600VA | Standard screw terminals; avoid loose connections. |
| Magnetic Low-Voltage (MLV) | 50VA | 600VA | Requires common-neutral pairing; test for 60Hz hum post-install. |
| Electronic Low-Voltage (ELV) | 50VA | 600VA | Reverse-phase mode; confirm transformer compatibility. |
| LED | 2W per fixture | 250VA total | Use dedicated LED-rated settings; flicker indicates poor pairing. |
Ground the device to the circuit’s earth wire (green or bare copper) via the designated screw terminal–skipping this step violates NEC 404.9(B) and risks arcing. For multi-location control, pair a matching remote switch (e.g., DV-RS) by linking traveler wires between units; confirm dimming synchronization before securing faceplates. Troubleshoot erratic behavior by measuring voltage at the load terminals: fluctuations above 5% suggest incompatible transformers or excessive circuit length.
Adjust sensitivity for low-load scenarios using the trim potentiometer accessed via the faceplate’s pinhole. Rotate clockwise to increase minimum brightness (useful for LED arrays), counterclockwise to reduce residual glow (critical for halogens). Verify phase-cut mode via a oscilloscope if flicker persists–forward-phase for MLV/incandescent, reverse-phase for ELV/compatible LEDs. Always power down the circuit breaker before adjustments to prevent component damage.
Identifying Terminals on the DV 600P Phase-Adjustable Controller
Locate the device’s faceplate–terminals are marked on the metal mounting strap behind it. The central screw, typically copper or brass, connects to the load (e.g., luminaires). Flanked by it are two black screws: the right one links to the neutral conductor, while the left accepts the line (hot) input from the breaker panel. Confirm labels by tracing the printed silkscreen on the strap; markings may read “L” (line), “N” (neutral), and “Load” or use symbols like “⏚” for ground if applicable.
Verify terminal assignments with a multimeter before energizing. Set the device to a mid-brightness setting, then probe:
- Line screw to ground: ~120VAC (for 120V systems).
- Neutral screw to ground: 0VAC.
- Load screw to line: ~120VAC at full brightness, dropping to ~20-40VAC at minimum.
Deviations suggest miswiring–recheck connections against the installation manual’s schematic.
For three-way configurations, an additional red screw appears–this links to the traveler wire from the companion switch. Wire colors often follow:
- Black: Line (primary switch) or traveler (companion switch).
- Red: Traveler (primary switch) or load (companion switch).
- White: Neutral (always required for LED compatibility).
Cap unused travelers with wire nuts to prevent shorts.
After securing connections, power up and test dimming range. If flickering occurs, swap the line and load wires–phase-adjustable models are polarity-sensitive. For persistent issues, inspect for loose screws or stripped wire strands; torque to 12-15 lb-in using a precision screwdriver.
Single-Pole Switch Hookup: Detailed Installation Process
Disconnect the circuit breaker supplying power to the load you intend to regulate. Verify the absence of current with a non-contact voltage tester on both terminal screws and the supply cables. Failure to confirm this step risks electrical shock or damage to the device.
Identify the hot (live) conductor–typically encased in black or red insulation–and the neutral line, which is usually white. The bare or green wire serves as the grounding path. Examine the switch’s rear labeling: the brass screw accommodates the hot lead, while the green screw secures the ground.
Strip 3/8 inch of insulation from the hot wire using wire strippers. Loop the exposed copper clockwise around the brass terminal screw until snug. Tighten the screw with a flathead screwdriver to 12–15 inch-pounds of torque; overtightening may strip the threads or damage the conductor.
Attach the grounding wire to the green screw using the same clockwise looping method. Ensure the grounding path extends to the electrical box if it is metallic. For plastic enclosures, connect the ground directly to the switch terminal only.
Route the remaining black or red conductor from the load (light fixture, fan, etc.) to the switch’s second brass terminal. Apply identical stripping, looping, and tightening procedures. Misalignment here results in intermittent operation or complete failure.
Fold the connected leads neatly into the electrical box, avoiding sharp edges that could chafe the insulation. Secure the switch to the box with the provided mounting screws, ensuring it sits flush against the wall plate without binding the wires.
Restore power at the circuit breaker and test the switch by cycling it on and off. If the connected load fails to respond, recheck terminal connections, grounding continuity, and breaker functionality. Dimmer units may exhibit a slight delay when toggled due to internal circuitry.
Snap the wall plate into place once functionality is confirmed. For dimming applications, note that incandescent, halogen, and compatible LED loads will behave differently; refer to the device’s compatibility chart for optimal bulb selection.
Connecting the DV 600P Dimmer for Multi-Location Control
For a three-way setup, identify the power source wire (typically black) and connect it to the common terminal on the primary switch. The two remaining travelers (often red and white or differently color-coded) must run between both switch locations–attach one to each traveler terminal on the DV unit and the corresponding terminals on the remote toggle. Confirm the dimmer is positioned at the first switch location where the load terminates, not the intermediate point.
Verify the neutral conductor is present if required by local electrical codes; some configurations may need it connected to a bundled neutral terminal, while others omit it entirely. Label all wires before disconnecting existing hardware to prevent misconnections. The load wire (usually blue or similarly designated) should exit the dimmer’s dedicated terminal and proceed directly to the fixture, avoiding splicing unless specified in the installation guide.
Match the traveler wires precisely–swapping them at either end reverses the switch’s on/off behavior across locations. Test continuity with a multimeter before energizing to ensure no shorts exist. If the remote switch fails to respond, check for a loose traveler or incorrect terminal assignment; reterminate if necessary. The dimmer should default to off when first powered, allowing gradual brightness adjustment during initial testing.
Adjust the dimming range by accessing the device’s rear settings if the load flickers or fails to reach full brightness. Some LED or CFL bulbs require compatibility mode activation via internal dip switches–consult the documentation for load-specific adjustments. Avoid exceeding the unit’s wattage rating (600W for resistive, lower for inductive loads) by confirming total fixture wattage beforehand. Overloaded conditions risk overheating or premature failure.
Secure all terminals with a torque screwdriver set to manufacturer-specified inch-pounds (typically 12–18) to prevent arcing. Insulate unused conductors and cap them with wire nuts to meet safety standards. If integrating with a smart home system, follow separate pairing instructions post-installation; Wi-Fi or hub-based controls may require additional bridge devices or power cycling to synchronize.
Troubleshoot dimming inconsistencies by isolating the circuit–remove the remote switch and test the dimmer alone to rule out traveler faults. Replace incandescent loads with compatible dimmable LEDs if buzzing occurs, and ensure no abrupt voltage drops are present along the line. For multi-gang boxes, space the dimmer apart from other electronics to minimize interference, and avoid adjacent placement with transformers or ballasts.
