bare ground wire on the
control (if present) to
the green or bare
copper ground wire in
the wallbox.
• Connect the red wire on
the control to one of the
wires leading to the
3-way switch.
• Connect the red/white
wire on the control to
the other wire leading to
the 3-way switch.
• Connect the yellow wire
on the control to the
wire leading to the load

Important Notes
Please read before installing.
1. CAUTION: To avoid overheating and possible damage to other
equipment, do not use to control receptacles, fluorescent lighting
fixtures, motor-operated or transformer-supplied appliances.
2. Use only to control the primary side of electronic transformer-
supplied low-voltage lighting, or in combination with
incandescent lamps.
3. This product requires a neutral wire in the wallbox. If a neutral
wire is not present, contact a licensed electrician for installation.
4. Some fixture manufacturers do not recommend dimming their
solid-state transformers. To determine if a fixture may be
dimmed, consult Lutron or the fixture manufacturer.
5. This control is overload protected. If the rated wattage is
exceeded, power to the circuit will shut off until the control cools.
If this occurs, remove excess load from the circuit.
6. Control may feel warm to the touch during normal operation.
7. In multi-phase applications, use a separate neutral for each
phase containing a dimmed circuit.
8. If a bare copper or green ground connection is not available in
the wallbox, contact a licensed electrician for installation.
9. For new installations, wire a test switch before installing the
control.
10. The wire connectors provided are suitable for copper wire only.
Refer to Step 5 for proper wire strip lengths.
11. Install in accordance with all national and local electrical codes.
Multi-Unit Installations
When combining controls in a wallbox, remove all inner side
sections prior to wiring (see below). Use pliers to bend side
section up and down until it breaks off. Repeat for each side
section to be removed. Reduction of control capacity is also
required. Refer to chart below for maximum control capacity.
