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.

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

C (32

F) to

C (104

F). 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.

** Only NF-10 may be used with Lutron Ballasts. Total Amps are determined by

adding all ballast line currents as indicated on ballast label.

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.

Single Unit Installation Figure E: Side Section Removal 1. TURN POWER OFF at fuse box or circuit breaker. Wiring with power on can result in personal injury. Damage caused by wiring with power on will void the warranty. 2. Side section break-off points Remove wallplate and slider from control to prevent surface damage and to access mounting holes. Pull out at top and bottom edges, plate will snap off. 3. 4. Wire each control according to Steps in "Single Unit Installation" on page 3. 5.

Turn power ON. NF-10/NF-10-277 with Lutron Ballast 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 ﬂicker 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.
