Important Notes
Please Read Before Installing

Wallbox and Location: A single-gang wallbox (3 in high x 2 in

wide x 2.5 in deep) 76 mm high x 51 mm wide x 64 mm deep))
will service all individual Nova controls. These controls are
designed to operate in ambient temperatures from 0 oC (32 oF) to
40oC (104 oF). Allow a minimum space of 4.5 in (114 mm) above
and below the control for proper heat dissipation.

Short Circuit Check: Check new installation for short circuits
prior to installing control. With POWER OFF, connect incoming
neutral to the white wire, and the hot wire to both ballast input
wires (black wire with brown wire or yellow/blue wire or orange
wire, depending on ballast used). Turn power ON. If lights do not
work, or breaker trips, a short is present. Correct the wiring and
check circuit again. Install control only when short is no longer
present. This check should be done by a qualifi ed electrician.

Sockets: Use only with rapid start lamp sockets. Lamp
disconnect sockets may be required for use with certain
manufacturer's ballasts. This is in order to meet U.L. and NEC®
regulations and maintains personal safety standards. Lutron
does not require lamp disconnect sockets with their ballasts.
Refer to the manufacturer's ballast label for this information.

Lamps: Use only rapid start fl uorescent lamps. Energy Saver
Lamps may NOT be used with this control. With magnetic
ballasts only, do not mix different wattage lamps in the same
circuit. NOTE: For proper dimming performance lamps must be
operated at full intensity for 100 hours prior to dimming.

Ballasts: Use ONLY dimming ballasts listed on chart in step 2 of
Pre-Installation. With magnetic ballasts only, do not mix 1 and
2 lamp ballasts in any one control circuit. Do not mix ballasts
manufactured by more than one company. Using single lamp
ballasts will produce the most consistent low end dimming level.

Multi-phased Applications (120/208-3 Phase): In multi-phased
applications use a separate neutral for each phase containing a
control. Contact the Lutron Technical Support Center toll-free
for Application Note #17, "Common Neutral Interaction".

Clean control with a soft damp cloth only. DO not use any
chemical cleaners.

Pre-Installation

1. Determine the number of controls to be ganged in the same

wallbox. If installing a single control in a wallbox, continue to the
"Single Unit Installation" section on page 3.

2. If more than one control is being ganged in the same

wallbox, side sections can be removed to fi t in existing
wallboxes. When controlling magnetic ballasts, breaking side
sections off the control will reduce the maximum number of

lamps per control. Use the following charts to determine the
maximum number of lamps per control.

Multi-gang Installation

In multi-gang installations several controls are grouped
horizontally in one ganged wallbox or in a series of
interconnected wallboxes. Multi-gang faceplates are
available to simplify and improve the appearance of these
installations. A multi-gang mounting frame is provided
with each standard multi-gang wallplate to ensure proper
alignment of controls, easy application of the wallplate,
and a fl at surface for the installation. This frame is most
easily mounted on the wall before control wires are
connected. Refer to multi-gang instruction sheet supplied
with multigang wallplate.

4. Wire each control according to Steps in "Single Unit

Installation" on page 3.

5. Install controls in wallbox(es). When combining

small and large controls, place all small controls on one
extreme end of the gang, and large controls at the other
end of the gang. Use center and offset mounting holes
as required for proper alignment. Allow
between controls for ease in attaching wallplate. See
Figure D.

No Side Sections Removed
(No Derating Required)

Installation of controls without removing side sections
allows operation at full capacity (i.e., no derating
is required). Follow instructions below. For retrofi t
installations, side sections can be removed to fi t existing
wallboxes. See Multi-gang Installation, "Side Sections
Removed" at right.

1. Assure safe operation by using Ballast Chart (Figure

A) to determine maximum number of lamps safely used
with specifi c ballast. Note: Use ONLY dimming ballasts
listed on chart. Do not use any other ballasts.

2. Determine the number of wallboxes necessary by

using Wallbox Requirement Chart in Figure B. When
ganging any combination of "small" (NF-10) and "large"
(NF-20, NF-30, NF-10-277, NF-20-277) controls, place
all small controls at one end of the gang and all large
dimmers at the other end.

Side Sections Removed
(Derating Required)

1. Derating is necessary when side sections are

removed. Use Derating Ballast Chart in Figure A. Match
the control size, number of side sections removed, and
the ballast type to determine maximum safe load.

2. Determine number of wallboxes necessary by

using the Wallbox Requirement Chart in Figure E. When
ganging any combination of "small" controls (NF-10) and
"large" (NF-20, NF-30, NF-10-277, NF-20-277) controls,
place all small controls at one end of the gang and all
large controls at the other end.

Cutting Wallplates When Removing Side Sections:

Wallplates will need to be cut if side sections are
removed when not using a multi-gang wallplate. Place
wallplate on a soft cloth face down. Press fi rmly and
score the groove on the back of wallplate with a razor
sharp knife, using vertical groove to keep knife on a
straight course. Bend section back and forth to break
it off. Smooth edges by placing fi ne-grained sandpaper
on a fl at surface and rubbing edge of wallplate over the
sandpaper a few times. Hold wallplate steady as you rub
to keep a straight edge. See Figure H.

7. Turn power ON.

8. For Lutron electronic ballasts ONLY:

This control is factory-calibrated and does not require
low-end light adjustment when used with Lutron FDB or
ECO-10 electronic ballasts. If lamps fl icker or drop out
at minimum dimming level, there may be an installation
error. Continued use of the system in this mode will cause
premature lamp failure. If this condition exists, call the
Lutron Technical Support Center at: 1-800-523-9466.

For magnetic ballasts ONLY:

a) Run lamps at full intensity (slider at top position) for

15 minutes to warm lamps. Note: For proper dimming
performance lamps must be operated at full intensity
for 100 hours prior to dimming.

b) After 15 minutes push slider to low intensity position

(as far down as possible without clicking off).
c) Locate trimpot adjustment shaft shown in Figure J.
d) Minimum light intensity is initially set at the factory.

Use the screwdriver provided to turn the trimpot screw

(inside trimpot shaft) clockwise to increase light level

and counterclockwise to lower light level.

Important note for magnetic ballasts ONLY: If lamps
fl icker when trimpot adjustment shaft is adjusted from
factory setting then turn shaft (as shown in Figure J)
clockwise until lamps cease to fl icker.

9. Replace slider and snap wallplate on dimmer by

pressing fi rmly at the top, center, and bottom tabs.
