**

• **At least one HomeWorks Digital 0.1% Controller

**

• **At least one compatible LED Load (light engine) 3

**

1. See list of compatible controls on the reverse side.
2. Please refer to the control installation sheet for wiring instructions.
3. Refer to LED load manufacturer instructions for proper installation practices.  

Load ratings must match controller output ratings.

MOUNTING INSTRUCTION

Mounting (mount as shown on the right)

1. Remove top cover to access multi-sided mounting key holes.
2. Mount controller per the options shown to the right.

Notes

• Minimum of 3 in (76 mm) required between any two LED controllers.
• Install in accordance with all national and local electrical codes.
• Mount controller in a position where it can be easily located and accessed if service or troubleshooting is necessary.
• Any other mounting configuration will require additional mechanical support. Improper installation may result in hazards to personnel or property.

Wiring (wire as shown below)
! WARNING: Shock Hazard. May result in serious injury or death. Turn off power at circuit breaker before installing the unit.

1. Remove top cover to access the terminal blocks.

2. Open necessary knockouts to pass wires into the wiring compartment.

3. Connect the necessary wires according to the illustration below. For HD1 / HD2 wiring, please refer to Application Note #142 at www.lutron.com. Terminals accept 12 AWG to 20 AWG (0.50 mm2 to 2.5 mm2).

4. Optional – An AC line cord may be used for a 120 V~ application. The line
   cord must include a grounded plug to be a valid installation as shown to the right. 277 V~ applications cannot use a line cord, they must be hard-wired.

5. Optional – Add barrier between non-Class 2 and Class 2 wires (e.g., HomeWorks digital wiring shown below has HD1 / HD2 as Class 2, therefore barrier is placed between input and control terminal block).

6. Rotate Field Adjustment Knob to full counter-clockwise position.

7. Ensure compatible dimmer and load are installed and restore power to the circuit. See reverse side for Compatible Controls.

3- Wire Controls

A barrier (included) in the wiring compartment separates non-Class 2 and Class 2 wires. Barrier can be placed between control and output terminals (Option 1) or between input and control terminals (Option 2).

  Consult individual component installation guides for more details.

Controller Leads

Maximum wire length between LED controller and start of the light engine:

• To use wire gauges larger or smaller than terminal blocks’ rated gauge of 20 AWG to 12 AWG (0.50 mm2 to 2.5 mm2), connect 12 in (30 cm) or less of rated wire from terminal and connect with larger or smaller wire.

Field Adjustment Knob

Adjusting knob on the outside of the enclosure changes  the minimum light level that is reached during normal  operation. This feature enables the user to address light  output mismatch between two or more controllers at  low-end dim level. The controller is initially defaulted to  the minimum light output when at low-end. For more  information, please refer to Application Note #591 (P/N 048591) at www.lutron.com

1. Ensure knobs on all controllers are in the full counter-clockwise position.
2. Set control to get lowest light level.
3. Turn knob clockwise to adjust light output to match the brightest controller.
4. Repeat steps 2-3 for the remaining controllers.

FCC

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:

1. This device may not cause harmful interference
2. This device must accept any interference received, including interference that may cause undesired operation.

277 V~ NOTE: This equipment has been tested at 277 V~ and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at their own expense.

120 V~ NOTE: This equipment has been tested at 120 V~ and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
