(70mm) for Accessory Controls and 3-1/2" (89mm)
for GRX-4000 Series Control Units.
Multigang installations may require spacers between
wallboxes.
Mount wallboxes flush to 1/8" (3mm) below finished
wall surface.
Finished wall should not have gaps around the
wallbox of greater than 1/8" (3mm).

Notes:
• Keep length of raceway below 24" to avoid possible
derating (per NEC code for 10 or more conductors).
• Panel generates heat (see table at right). Mount
only where ambient temperature will be 0-40°C
(32°F-104°F).
• Reinforce wall structure as required for weight and
local codes.
• Panel clearances are 1-1/2" (38mm) to each side.
• Distribution Panel not included with XP Series Panel.
• Indoor Use Only. Type 1 enclosure.
• Relative Humidity < 90% non-condensing.
• XP Panels should be mounted within 7° of true
vertical.

Caution - Wire in a daisy-chain
arrangement as shown - no variations.
Do not substitute cables!
Notes:
• All control wiring is Class 2 (Extra Low Voltage).
Do not place any of these wires in with line voltage
(mains voltage) wiring.
• Panel may be placed in the middle of the wiring as
opposed to on the end as shown, but panel to
panel wiring may be more difficult.
• 2 #12 AWG (2.5mm2) wires will not fit in the
Accessory Control terminal blocks. Use the
diagram shown at right to make the connections
in the wallbox. #12 AWG (2.5mm2) is necessary
due to voltage drop on the wire.
• Shielding must be connected as shown, but do not
connect to Ground (Earth) or Accessory Control. It
is easiest to connect the bare drain wires and cut
off the outside shield.
• Make wire connections inside the wallbox, GP and
XP panel or in a junction box (provided by others)
within 8ft. (2.4m) from the terminals.

Notes:
• Terminal blocks accept one #14 AWG (2.5mm2)
through #10 AWG (4.0mm2) or two AWG #18 AWG
through #16 AWG wire.
• Two modules and the control feed are shown to the
left. The module terminal blocks are typical of the
rest of the possible 12 modules
• Lutron recommends that the Control Feed be a
dedicated circuit even though the control wiring
will draw 0.5 Amps max.
Danger - An XP Series panel is fed by
multiple circuits. Locate and lock each
feed in the OFF position.
Caution - XP Series panels require entry
of wires as specified. Improper entry will
block serviceable parts or violate NEC codes.
Warning - Do not remove bypass jumpers
at this step.

STEP 6: Install Controls
After completing steps 4 and 5, mount controls.
Refer to detailed mounting instructions packaged with
each control.
STEP 7: Activate Loads in Bypass
A. Check that the bypass jumpers are in place.
These jumpers protect the switch mechanism from
wiring faults and must be used to check load wiring
when it is installed or modified.
B. Complete load wiring.
C. Turn a load’s input circuit breaker ON.
The loads should energize, the feed breaker should
not trip, and total load current must be no more
than 16 Amps.
D. Repeat ‘C.’ for each circuit with completed load
wiring.

Controls
STEP 15: Set Up Accessory Controls
All Accessory Controls (except NTGRX-1S) must be
set up to make a Control Unit(s) “listen” to button
presses on the Accessory Control.
• Only one Accessory Control can be set up at one
time.
• A Control Unit can also be made to “listen” to
another Control Unit and is therefore listed with the
Accessory Controls at right.
Follow Steps A-C for each Accessory Control.
Notes:
• Accessory Controls can not be made to “listen” to
each other , but a GRX-4000 Series Control Unit
can be made to “listen” to more than one
Accessory Control.
• When it is desired for two GRX-4000 Series
Control Units to always respond to each other’s
button presses, the first Control Unit must be set up
to respond to the second Control Unit’s buttons,
and then the second Control Unit must be set up to
respond to the first Control Unit’s buttons.
• An NTGRX-1S is wired directly to the GRX-4000
Series Control Unit that is to “listen” to it. No set-up
is required.
• GRX-AV-RS232’s do not follow this chart. See
instructions packaged with each control.

STEP 16: Set Normal/Emergency Switch
(Non-Essential/Essential)
Note:
This step is only performed if there are any panels
with Emergency (Essential) Lighting Circuits on
the job.
Panels are shipped with Switch 6 (located at the base
of each Circuit Selector) in the center position for
operation without any Emergency (Essential) Lighting
Circuits.
Identify a panel supplied with Normal (Non-Essential)
power. Move its Switch 6 to the left position.
For all the Emergency (Essential) Lighting Panels,
move switch 6 to the right position.
In this arrangement, the Emergency (Essential)
Lighting Panel will “sense” the Normal (Non-Essential)
Panel’s power. When Normal (Non-Essential) power
is removed, the Emergency (Essential) Lighting will
go to ‘ord’ override levels (factory set to ON).
Loss of Normal (Non-Essential) power can be
simulated by turning off all connected Normal (NonEssential) Panels’ Control Breakers.
When Switch 6 is left in its center position (as
shipped), terminal 5 has no affect on the Circuit
Selector operation.

XP Series Switching Panels
The XP Series Switching Panel has 1 to 12 Switching
Modules and a Circuit Selector to set up Zone
Assignments and Load Types.
Each Switching Module has four switching
mechanisms. Each switching mechanism connects
or disconnects 16 Amps max. from Hot to Switched
Hot based on the intensity of its assigned zone of a
GRX-4000 Control Unit.
XP Series Panels are designed to mount between two
studs that are on 16" centers. Each panel may be
mounted in or on a wall.
All XP Series Panels have a Type 1 enclosure, are UL
listed under UL file 42071, and are CSA certified.

Notes:
• The additional #18 AWG (1.0mm2) wire is a ‘sense’
line from terminal 5 of another panel. This sense
line allows an Emergency (Essential) Lighting
Panel to ‘sense’ when Normal (Non-Essential)
power is lost.
If more than one Emergency Lighting Panel needs
to sense off a specific Normal panel, a dedicated
wire may need to be run between each pair of
Normal (Non-Essential) and Emergency (Essential)
panels.
• Shielding must be connected as shown, but do not
connect to Ground (Earth) or Circuit Selector. It is
easiest to connect the bare drain wires and cut off
the outside shield.

Circuit Selector Functions
Circuit Selector Functions
Circuit Selector listens to the GRX-4000 Series
Control Unit(s) and then tells the circuits whether to
be ON or OFF.
It can also be used to select Values for each Circuit:
• Load Type - allows the switch to operate at
specified times:
1,2,3,5 = Do not use for XP series
4 = Non-dim with load turned ON as the GRX
4000 Series Main Unit’s intensity changes
from below 100% to 100% (last ON), and
turned OFF as the intensity goes from
100% to below 100% (first OFF).
6 = Non-dim with load turned ON as the GRX
4000 Series Main Unit’s intensity changes
from 0% to 1% (first ON), and turned OFF
as the intensity goes from 100% to below
100% (first OFF).
– = Unassigned
• Control and Zone Assigned - allows two ways of
assigning a control and zone to a specific circuit.

Maintenance
Reference Sheet
XP Series Panels
Danger - Any liquid entering the panel
may reach internal components, cause
personal injury, damage the equipment,
and void the warranty.
1. If any extra wiring is brought into the panel,
temporarily cover the modules and thoroughly
remove all metal chips, wire strands, insulation,
or other debris before reapplying power.
2. In the unlikely event of damage to switching
equipment, replace bypass jumpers (see step 11).
This will take the switching equipment out of the
circuit and apply full power to fixtures.
3. To take manual control of the On or Off state of any
circuit, use the Circuit Selector (see Troubleshooting
Guide).
4. The exterior of the XP Panel may be painted as
follows:
a. Remove the front cover.
b. Cut a piece of paper slightly smaller than the
cover label (label is 7" x 2.675" with rounded
corners)
c. Tape the cut paper onto the label so that the tape
holds the paper and completely covers the
label. Avoid taping any of the label except the
outside edge.
d. For the cover or painted enclosure, sand the
existing paint to roughen it. For galvanized
enclosure - wipe the outside (do not paint the
inside) surface with a damp, soapy cloth.
e. Paint the cover or enclosure exterior. For
galvanized enclosure, use an acrylic (OVM
recommended) or urethane paint - not an oil
based paint.
Warning - When painting the panel cover,
keep all vent holes open and clear of any
paint pooling.
Danger - Turn power off before working on
any load. Each circuit may have an
individual, external disconnect switch.
Locate and lock the appropriate
disconnect switch (usually a breaker)
before servicing.
Warning - When working on any load
(such as rewiring a load), replace the
bypass jumpers to protect the switching
module until the load is proven.
GRX-4000 Series Control Units and Accessory
Controls
Clean front surface of control with a soft towel
moistened with a mild soap solution (nonammonia- based). Clean approximately every six
months.
Caution - Do not spray cleaning solution
onto control as it may reach internal
components.
Fixtures
It is important that lamps are maintained properly to
prevent what may appear as switching equipment
malfunctions. When lamps begin to fail on a circuit,
Lutron recommends group relamping of the entire
circuit.

Accessory Control - GRAFIK Eye control wired to a
GRX-4000 (or GRX-3000) Series Control Unit to
select scenes, raise and lower specific zones or
other functions on an attached Control Unit.
Addressing - a way for the controls on a link to
identify each other. Accessory Controls are
addressed from the back, using switches 1 through
4 on the back of each control. Each control needs
a unique address, GRX-4000 Series Control Units
are addressed while in Set-Up Mode from the front
panel’s buttons.
Circuit Selector - the interface between the GRX-
4000 Series Control Units and the Switching
Modules that reside in an XP panel. The Circuit
Selector houses all Circuit Values including Load
Type and Control and Zone assigned.
Control Link - the daisy-chained link of controls
powered by the XP Panel. A maximum of 8 GRX4000’s and 16 Accessory Controls may be wired
together to form a link (any number of NTGRX-1S’s
can be used in the SSA terminal).
Fade - a gradual change in zone intensity in a room
or space.
Fade Time - Selected time interval to change from
one scene to another. A GRX-4000 (and GRX-
3000) Series Control Unit has a customer-settable
fade time that ranges from 0-59 seconds and 1 to
60 minutes.
GRX-4000 Series Control Unit - a control on the
control link that allows zone intensities to be set for
up to 16 scenes. Control Units are available in 2,
3, 4, 6, and 8 Zone varieties.
Job - name of a location where GP, LP or XP Series
Panels and GRX-4000 Series Control Units are
being/have been installed.
LED (Light Emitting Diode) - an illuminated indicator
to help in setting up and diagnosing XP Panel and
GRX-4000 Series Control Unit’s functions.
Load Type - a value in the Circuit Selector that
defines the performance of the circuit to optimally
control the following: 1) Incandescent, 2) Hi-lume
FDB or Eco-10 Dimmable Fluorescent, 3) Neon, 4)
Non-Dim, 5) Electronic Low Voltage, and 6)
Screen Non-Dim. Only Load Types 4) and 6) are
valid in an XP Series Panel.
Non-Dim Load - a source that is not to be dimmed.
Load Type for that circuit is to be set to Load Type
4 or 6 only. In an XP Series Panel, all loads are
Non-Dim loads.
Scene - (or Preset) - Predetermined light intensity for
one or more lights, creating a lighting effect that
can be recalled by pressing a single button. The
GRX-4000 Series Control Unit has Scene 1-4 and
OFF accessible on the front of the control. Some
Accessory Controls can be Set-Up to access
Scenes 5-16.
SM - Switching Module - a group of up to 4 switching
mechanisms in a module which can each switch up
to 16 Amps of various load types.
SSA - Single Scene Activator (model # NTGRX-1S)
alternately toggles the GRX-4000 (or GRX-3000)
Series Control Unit to which it is wired between
Scene 1 and OFF. This control is not counted as
an Accessory Control and multiple SSA controls
can be wired in parallel controlling the same
GRX-4000. Usually used for Entrances.
XP Series Panel - Switching Panel - includes 1 to 12
Switching Modules (SM’s) which will switch 4 16A
loads each.
Zone - a fixture or a group of fixtures controlled
simultaneously. The GRX-4000 Series Control Unit
controls multiple zones (e.g. a GRX-4108 can
control 8 zones). Each zone can be assigned to
one or more Circuits in a XP Panel. Each zone
should only control one Load Type.
Zone Capture TM
- a method of Assigning a Control
and Zone to a circuit without knowing Control
Addresses. See ‘Circuit Selector Functions’ in the
Reference Section.
