Wiring Notes
• System Maximums
— GRAFIK Eye® QS series control units can each
power a maximum of 3 wallstations.
— 610 m (2000 ft.) maximum wiring length
— 0-40 °C (32-104 °F) operating temperature.
— 100 devices per link (seeTouch® QS, Sivoia®
QS, power panel, and GRAFIK Eye QS each
count as one device); 100 zones maximum
per link
• Refer to the system installation guide for power cable
and data ca ble (control link) wiring restrictions and
limitations.
• Control Link Wiring
— Power: Two 1.0 mm2 (#18 AWG) PELV (Class
2: USA) wires. Connect to terminals 1 and 2.
— Data: Two shielded 1.0 mm2 (#22 AWG) PELV
(Class 2: USA) wires (twisted, shielded pair).
Connect to terminals 3 and 4.
Lutron offers a one-cable, non-plenum, low-
voltage solution (P/N GRX-CBL-346S-500), and
a one-cable, plenum, low-voltage solution (P/N
GRX-PCBL-346S-500). Check availability outside
the U.S.
• Sensor/Contact Closure Input Connector Wiring
(optional):
— Three 1. 0 mm2 (#18 AWG) PELV (Class 2: USA)
wires.
• Connect the wallstation to the control link inside the
wallstation’s wallbox or in a junction box (provided by
others).
• Control link wiring must not be run in the same
raceway as line voltage.
• Control link wiring is not to exceed 610 m (2000 ft.).
• The drain/shield wire must be maintained throughout
the control link. Do not connect the shield to earth/
ground or allow contact with the grounded wallbox.
Wallstation circuits are classified as Class 2 circuits
(USA) and PELV circuits (IEC). As Class 2 circuits,
they comply with the requirements of NFPA® 70,
National Electrical Code® (NEC®). As PELV circuits,
they comply with the requirements of IEC 60364-441, VDE 0100 Part 410, BS7671:1992, and other
equivalent standards. When installing and wiring to
these wallstations, follow all applicable national and/
or local wiring regulations. External circuits connected
to input, output, and other communication terminals
of wallstations must be supplied from a listed Class
2 source or comply with the requirements for PELV
circuits, as applicable in your country.
Safety Notes
• Read all instructions carefully before starting
installation.
• Lutron recommends that wallstations be installed by
a qualified electrician.
• Do not connect high-voltage power to lowvoltage ter mi nals. Improper wiring can result in
personal injury or damage to the control or to other
equipment.
• Use only a cloth with warm water and mild soap to
clean faceplates (no chemical cleaners).

Warning! Shock hazard. May result in
serious injury or death. Always turn OFF the
circuit breaker/MCB or remove the main fuse
from the power line before doing any work.
1. Turn Power OFF. Turn power OFF as
circuitbreaker/MCB (or remove fuse).
2. Mount Wallbox. Wallstations mount in a Lutron
wallbox (P/N 241-683) or in German and UK
backboxes (60.30 mm measured center to center of
mounting holes).
3. Prepare Wallstations. Remove the faceplate and
set aside.
4. Prepare wires. Strip insulation from wires so that
9.5 mm (3/8 in.) of bare wire is exposed.
9.5 mm (3/8 in.)
Each wallstation terminal accepts up to two
1.0 mm2 (#18 AWG) wires.
Note: Wiring may be done in a Daisy-Chain or
T-Tap configuration, as shown below.

Connect two 1.0 mm2 (#22 AWG) shielded, twisted pair
wires to terminals 3 and 4 of the wallstation’s control link
connector. Shielding (drain) of the twisted pair wires must
be connected together as shown, but do not connect
the shielding to earth/ground or the wallstation and do not
allow it to contact the grounded wallbox.

6. Connect the Wallstation to external contact
closure inputs (optional). If using one contact
closure input, connect the input to terminal A of the
wallstation sensor/contact closure input connector. If
using two contact closure inputs, connect the inputs
to terminals A and B. Connect the common side of
the contact closure inputs to terminal C.

Contact Closure Input Wiring
Notes for Contact Closure Inputs:
Verify compatibility of external contact closure input
devices. The contact closure inputs can be used
with either dry contact closures or ground-referenced
solid-state outputs. The outputs must stay in the
closed or open states for at least 40 msec in order
to be recognized by the wallstation. If there is any
question as to whether the device is compatible with
these specifications, contact the manufacturer.
Contact closure input function is determined by the
programming of the top and bottom buttons of the
left column of the wallstation.

7. Mount Wallstation. Carefully mount and align
the wallstation as shown. Screw top and bottom
mounting screw into the control and wallbox.
Replace the adapter (for insert versions) with the
adapter screws. Then snap in the buttons and
faceplate.

8. Turn Power ON. Turn ON control breaker, or
replace main fuse.
Notes
• Unprogrammed (out of the box) QS wallstations
and control units will all work together until they are
reprogrammed otherwise.
