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
• 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
with the requirements of NFPA 70
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) .
