Operation
The Low-Voltage Ballast Control provides dimming control
for Lutron Eco-10 10 Volt Option Ballasts. The control
allows dimming to 10% when used with these 10%
dimming ballasts. Use this product only as intended with
recommended accessories.
Important Notes
Please Read Before Installation
Wallbox Dimensions: A single-gang wallbox (3" high x 2"
wide x 21/2" deep) will service all individual controls.
Wiring Note: Always turn off AC power before installation.
Install in accordance with all local and national electrical
codes.
Lamps: For proper dimming performance new lamps must
be operated at full intensity for 100 hours, prior to dimming.
Ballasts: A single Low-Voltage Ballast Control can be
used with a maximum of 60 Lutron Eco-10 10 Volt Option
Ballasts.
Do not connect this control to line voltage.
Relays: If wiring for ON/OFF and dimming, the LowVoltage Ballast Control must be used with the Lutron PP20 Power Pack.
Installation
1.
TURN POWER OFF to disable the 0-10 volt electronic
ballast(s) to be dimmed.
2.
Remove faceplate and slider from control to prevent
surface damage and to access mounting holes. Pull
on faceplate at top and bottom edges to snap off plate.
3.
Strip wallbox wires to the following lengths:
5
/8" for No. 16, 18 and 20 gauge
1
/2" for No. 10, 12 and 14 gauge
4.
Wire controls according to the appropriate wiring
diagram shown in the “Wiring” section on pages 2-3 of
this sheet and on the ballast.
5.
Carefully push wires into wallbox allowing room for the
dimmer back cover.
6.
Mount control into wallbox using screws provided.
Units must be mounted vertically. See Figure A.

Ballast Functionality Check: With power OFF, check
new ballast for functionality prior to installation of control by
connecting the ballast’s purple and gray wires together at
the control. Turn power on. The lights should now be at
minimum brightness. With power OFF, disconnect the
wires. Turn power ON. The lights should now be at
maximum brightness.

Turn power ON. Pushing slider up should increase
light intensity. Pushing slider down should decrease
light output to approximately 10% of the maximum light
level for 10% dimming ballasts.
The maximum light level intensity may be adjusted as
follows:
a.
9.
Push slider to the top-most position (maximum
light intensity) and run lamps for 15 minutes to
warm lamps.
b.
Locate trimpot adjustment shaft (see Figure A on
page 1).
c.
Maximum light intensity is initially set at the factory
to the maximum setting. Use the screwdriver
provided to turn the trimpot screw (inside trimpot
shaft) clockwise to decrease light level and
counterclockwise to increase light level.
Mount faceplate adapter plate with screws provided.
Replace slider and snap on faceplate. See Figure B.
Dimming Only (No ON/OFF Control)
Connect the control as shown in Figure C. Changing
slider position will alter light intensity from the ballast’s
maximum light intensity to minimum but not allow
lights to be switched off.

Connect the control as shown in Figure D. Use only
Lutron PP-20 Power Packs for AC line switching. Do
not install the PP-20 in the same wallbox as the LowVoltage Ballast Control. Refer to the wiring sheet
included with the PP-20 for more information.
Wiring
The total low-voltage wiring for this unit should not exceed
500 ft. with No. 20 AWG. For long low-voltage wiring runs,
or where excessive electrical noise exists, shielded cable
or conduit is required. A maximum quantity of 60 electronic
controllable ballasts can be connected to one control.
Install in accordance with all local and national electrical
codes.

offset mounting holes as required for proper
alignment. See Figure F. Allow 1/32" between controls
for ease in attaching faceplates.

Multigang Installation
Center Mounting Holes
In multigang installations several Low-Voltage Ballast
Controls can be grouped horizontally in one ganging
wallbox or in a series of connected wallboxes. Multigang
faceplates are available to simplify and improve the
appearance of this installation. A multigang mounting
frame is provided with each standard multigang faceplate
ensuring proper alignment of dimmers, easy application of
faceplate, and a flat surface for installation. This frame is
most easily mounted on the wall prior to connecting
dimmer wires. Refer to the instruction sheet supplied with
the multigang faceplate when using these components.
For retrofit installations, the side sections can be removed
to fit existing wallboxes (refer to the section “Multigang
Installation – Side Sections Removed” on pages 3-4).

Multigang faceplates, which eliminate the need to

When ganging, use 3" x 2" gangable wallboxes. Do
not use plaster rings or gangbox covers. For an
EVEN number of controls, one control will be 3/4" apart
from the other wallbox(es) to provide necessary space
for the faceplate(s).
For example, when ganging four controls, three would
be in the four connected wallboxes and one would be
in a wallbox separated by 3/4". See Figure E.
Figure E: Wallbox Positioning Four-Ganged Controls
1.
One gangable wallbox is needed for each control in
the multiganged unit. Individually connect wallboxes or
use a pre-assembled multigang wallbox.
2.
Remove INNER side sections only. Using pliers, bend
side sections down as far as you can and then back to
their original positions. Side sections will break off.
NOTE: DO NOT REMOVE OUTER SIDE SECTIONS OF
THE TWO DIMMERS WHICH ARE ON THE ENDS OF
THE GANG.
3.
When mounting, use center mounting holes as
required for proper alignment. See Figure H.

When Removing Side Sections” below) and adjust up
or down for a snug fit. Multigang faceplates include
mounting frames and instructions. See Figure I.

LIGHTS DO NOT OPERATE AT FULL BRIGHTNESS:
• Push slider up. Turn trimpot counterclockwise with the
screwdriver provided to achieve maximum light
intensity.
• Check to see that purple and gray wires are not cross
connected in any fixture, conduit, or wallbox.
LIGHTS DO NOT DIM LOW ENOUGH:
• A dimming range of 100% to 10% should be achieved
for 10% dimming ballasts by moving the slider position.
Check the ballast output with a light meter in the
absence of other sources of illumination (or correct for
other sources) at both high and low light readings. The
ratio of the low reading and the high reading should be
1:10 or 0.1.
Multigang faceplates, which eliminate the need to
cut individual faceplates, are available in a variety
of colors to beautify and simplify your installation.
Cutting Single Faceplates When
Side Sections Are Removed
Single faceplates will need to be cut if side sections are
removed and a multigang faceplate is not used. Before
cutting the faceplate, place it on a soft cloth face down.
Then pressing firmly, score the vertical groove on the back
of the faceplate with a razor sharp knife — use the groove
to keep knife on a straight course as shown. Bend the
scored section back and forth to break it off. Smooth cut
edge by placing fine-grained sandpaper on a flat surface
and rubbing the edge over the sandpaper a few times.
Hold faceplate steady as you rub to keep a true edge.
When taking the high end measurement, the slider
should be at the top-most position and trimpot adjusted
to provide maximum light output. When taking the low
end measurement, the slider should be at the bottom
most position. Allow lamps to stabilize for a minimum of
10 minutes before taking readings.
• If the 100% to 10% dimming range is not achieved,
check to see that purple and gray wires are not cross
connected in any fixtures.
