Lutron GRAFIK Eye. NTGRX-4S Instructions D'installation page 3

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
®
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 terminals.
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.
