STEP 1: Mount Wallboxes
Use wallboxes with a minimum depth of 2-3/4"
(70mm) forAccessory 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.

• Maximum number of lighting control panels may
be increased using a repeater—contact Lutron.
• The following cables: Liberty #LUCOM-12/22-RBL,
Belden #9461, andAlpha #2211 are made with #22
AWG wire, and have been tested and approved.
Not all #22 AWG cable will work.Any #18AWG
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 #12AWG (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.
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
wiring.
Warning - DO NOT remove bypass
jumpers at this time.
