Control Units and LP Dimming Panels to dim
fluorescent lights that have Lutron Hi-Lume
®
and Eco-10TM (Eco-Series) line-voltage control
Electronic Dimming Ballasts.
• Models available for 120 V , 220-240 V
(non-CE), or 100 V input power.
Works with:
• GRAFIK Eye 3000 Series Control Units
• LP Dimming Panels
• HomeWorks Remote Power Panels
• Neutral-referenced wallbox dimmers by Lutron.

Power
• Input power: 120 V , 220-240 V (non-CE), or
100 V .
All voltages 50/60 Hz, phase-to-neutral.
• Load (output) power: Phase independent of Control
Unit.
Sources/Load Types
Operates Lutron Hi-lume
® and Eco-10TM (Eco-Series)
line-voltage control Electronic Fluorescent Dimming
Ballasts with a smooth continuous Square Law dimming
curve.
Key Design Features
Patented RTISSTM circuitry compensates in real time for
incoming line voltage variations: No visible flicker with
+/-2% change in RMS voltage/cycle and +/-2% Hz
change in frequency/second.
Terminals
Accept up to two #12 AWG (2.5 mm
2
).
Environment
32 - 104 °F (0 - 40 °C). Relative humidity
less than 90% non-condensing.
Mounting
Surface or recess mount indoors only.

• Recess or surface mount in 2-gang U.S.
wallbox 3.5 in. (89 mm) deep. Indoors only.
• FDBI Interface generates heat; mount only
where ambient temperature is 32 - 104 °F
(0 - 40 °C).
• Mount with arrows facing up to ensure
adequate cooling.
• Allow 4.5 in. (114 mm) above and below
unit and between faceplates when mount-
ing several in a vertical layout.
• For better heat dissipation, surface mount
without faceplate.
• Mount so line (mains) voltage wiring is at
least 6 feet (1.8 m) from sound or electron-
ic equipment and wiring.
• Mount Interface within 7° of true vertical.

• Pull #12 AWG (2.5 mm

) Copper (Cu) wires (75 °C minimum) for
input power and load circuit.
• Strip 1/2 in. (12 mm) insulation from wires before connecting.
• Run separate neutral for load circuit - no common neutrals.
Neutral (N) terminal is for Control Unit, not the load neutral.
Multiple Power Feeds
The FDBI may be on the same circuit as the
Control Unit only if the total load does not
exceed the rating of the breaker.
Wiring
Single Power Feed
The load breaker/MCB may be on a different phase than the control breaker/MCB.
With Other Lutron Lighting Controls
To wire an FDBI Interface to a fluorescent dimmer:
• Run a Neutral wire from the control equipment to Neutral N on the FDBI.
• Run a dimmed hot wire from the control equipment to Zone In on the FDBI.
