• Maximum number of lighting control panels may
be increased using a repeater—contact Lutron.
• The following cables: Liberty #LUCOM-12/22-RBL,
Belden #9461, and Alpha #2211 are made with #22
AWG wire, and have been tested and approved.
Not all #22 AWG cable will work. Any #18 AWG
twisted, shielded pair will work.
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 (2.5mm
2
) 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 (2.5mm
2
) 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.

Suggested wiring when panels are close together
Suggested wiring when panels are far apart
Notes:
• Terminal blocks accept one #14 AWG (2.5mm
2
)
through #10 AWG (4.0mm
2
) 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.
Caution - Lutron recommends the use of
a trough for ease of wiring (where space
permits).
Caution - Follow all local wiring codes.

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

STEP 8: Activate Controls
Once all controls are installed and wiring verified, turn
the control wiring feed circuit breaker ON.
Check that the Power OK LED at the top of the
Circuit Selector is ON. If the Power OK LED is
off, turn off the control breaker, check for shorts
between wires 1 and 2, or 2 and ground.
Note:
For multiple panels once one Power OK LED is
ON, all the Power OK LED’s in all system Circuit
Selector’s should turn ON.
Push scene buttons on Accessory Controls. All GRX-
4000 Series Control Units and Accessory Controls
should act in parallel (e.g. pressing scene 1 on a
control will select scene 1 on all controls, pressing a
raise button will raise all zones).
Notes:
• NTGRX-4Q, NTGRX-4PS, NTGRX-4M
and GRX-AV-RS232’s will be inactive until
Control Set Up is completed.
• GRX-AV will be active only if set to affect Scenes
1-4 and OFF (switches 5,6,7, and 8 all UP).
• NTGRX-2B will be active only if set to affect Scene
1 and OFF (switches 5 and 6 both UP).
• Check for miswires if the controls do not act as
described.

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 (Non-
Essential) Panels’ Control Breakers.
When Switch 6 is left in its center position (as
shipped), terminal 5 has no affect on the Circuit
Selector operation.
Notes:
• If there is no Normal Panel, contact Lutron
for GRAFIK Eye 4000 Application Note #5:
How to
create a ‘sense’ line.
• Override (‘ord’) Level is factory set to turn all circuits
ON. If the override level is to be OFF, contact Lutron
for GP Panel Advanced Function #1.
