Installation Instructions
Wallstation circuits are classified as Class 2 circuits (U.S.A.) and
PELV circuits (IEC). Unless otherwise specified, the voltages do
not exceed 24 VAC or 15 VDC. 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 60364-4-41, 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, RS232,
DMX512, 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.
CAUTION
!
■
Lutron recommends that Wallstations be installed by a
qualified electrician.
■
Do not connect high-voltage power to low-voltage termi-
nals. Improper wiring can result in personal injury or
damage to the control or to other equipment.
■
GRAFIK Eye
Wallstations must be connected to the
GRAFIK
Eye
Control Unit by using Class 2/PELV wiring methods per
the
National Electrical Code
. Check with your local electrical
inspector for the local code requirements and wiring
practices allowed in your area.
■
Use only a cloth with warm water and mild soap to clean
faceplates (no chemical cleaners).

Wallstation Wiring
— 3000 Series: Four #18 AWG (1.0 mm
2
) Class 2/PELV
wires (2 twisted, pair). 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-PCBL346S-500). Other suggested cables are
Belden No. 9156, Alpha No. 1132, or equivalent, for
GRAFIK Eye
3000 Series Control Units.
— 4000 Series: Two #12 AWG (2.5 mm
2
) Class 2/PELV
wires and two shielded #18 AWG (1.0 mm
2
) Class
2/PELV wires (twisted, shielded pair). Lutron offers a
one-cable (non-plenum), low-voltage solution (P/N
GRX-CBL-46L).
— Power: wires 1 & 2, 12 VDC-24 VFW.
— Data: wires 3 & 4, twisted, shielded pair.
