Step 5: Connect PELV (Class 2: USA) Cable to the
Control Unit — Optional
If your lighting system uses wallstations and/or multiple control units, PELV (Class 2: USA)
wiring is needed to supply power and carry communications between the control units and the
wallstations .
Important Wiring Information
• Lutron requires that you connect (daisy-chain) control units and wallstations with two twisted
pairs for operation . Each twisted pair in the PELV (Class 2: USA) wiring link should consist of
two #18 AWG (1 .0 mm
2
) stranded conductors .
• Use properly certified PELV (Class 2: USA) cable . For a description of recommended cable
types, refer to “PELV (Class 2: USA) Cables” on page 3 .
• Install in accordance with all local and national electrical codes .
• Wallstation circuits are classified as Class 2 (USA) and PELV (IEC) circuits . Unless otherwise
specified, the voltages do not exceed 24 V or 15 V . 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 . External circuits connected to input, output, RS232, Ethernet, DMX512,
and other communication terminals or wallstations, must be supplied from a Listed Class 2
source or comply with the requirements for PELV circuits as applicable in your country .
• The control unit’s low-voltage PELV (Class 2: USA) circuit is 12 V .
• The PELV (Class 2: USA) cable and terminal block should be separated from the line voltage/
mains cables by at least 1/4 in . (7 mm) .
* For phase-to-phase and delta-feed wiring, contact Lutron .
