Important Notes
Please read before installing
1. CAUTION: To reduce the risk of overheating and possible
damage to other equipment, do not use to control
receptacles, motor-operated appliances, or transformer-
supplied appliances.
2. This dimmer requires a neutral wire in the wallbox. If a
neutral wire is not present, contact a licensed electrician for
installation.
3. Use with Lutron FDB or ECO Series Electronic Fluorescent
Dimming Ballasts ONLY. Do not use with any other ballasts.
4. When no “grounding means” exist within the wallbox then
the NEC® 2005, Article 404-9 allows a dimmer without a
grounding connection to be installed as a replacement, as
long as a plastic, noncombustible wallplate is used. For this
type of installation, cap or remove the green ground wire on
the dimmer and use an appropriate wallplate.

Before Installation
Check new installations for short circuits prior to installation of
dimmer by installing a test switch (see wiring diagram on page
3). Turn power on. If lights do not work or if breaker trips, a short
is present. Correct the wiring and check the circuit again. Install
the dimmer only when a short is no longer present.

* As measured from incoming hot wire (blue) on dimmer. To
determine total load on the dimmer circuit, refer to ballast
label. Each ballast has an associated input current. Total
load is found by adding up all the ballast currents for all
ballasts on dimmer.
6. Use only the lamp types listed on the label of the ballast.
Compact fluorescent lamps must have 4 pins for dimming.
7. NF-103P and NTF-103P operate at 120 V only.
NF-103P-277 and NTF-103P-277 operate at 277 V only.
8. In multi-phase applications, use a separate neutral for each
dimmer circuit. If further information is necessary, contact
the Lutron Technical Support Center at 1-800-523-9466.
Please provide exact model number when calling.
9. Do not use two dimmers in the same 3-way circuit.
10. Wire the dimmer in accordance with all national and local
electrical codes.
11. Dimmers are designed to operate in temperatures between
0-°C and 40-°C (32-°F to 104-°F).
12. The wire connectors provided are suitable for copper wire
only. They can be used to join one No. 18, 16, 14, 12, or 10
gauge wire with one or two No. 14 or 12 gauge wires.
13. Clean dimmer with a soft damp cloth only. Do not use
any chemical cleaners.
Installation
If more than one control is to be installed in the same wallbox,
review Multigang Installation before starting.
1. WARNING: Turn power OFF at circuit breaker or remove
fuse. Wiring with power on may result in personal injury.
Damage to product caused by wiring with power on voids
warranty.
2. Remove wallplate from dimmer. Pull from top of wallplate
to remove. Set aside.
3. Trim or strip all wires to the proper length:
• 1/2 in. (13 mm) for 10, 12 and 14 gauge wire
• 5/8 in. (16 mm) for 16 and 18 gauge wire
4. Use wire connectors to wire dimmer as shown in Wiring
Diagrams (pages 3 and 4).
5. Push dimmer into wallbox. Do not pinch wires.
6. Mount dimmer to wallbox using screws provided.
