DALI bus wiring may be considered
NEC
®
Class 1 or PELV (Class 2: USA).
• NEC
®
Class 1: DALI
bus wiring may be
run in the same conduit as mains voltage
wiring to fixtures.
• PELV (Class 2: USA): DALI
bus wiring
must be separated from all mains and
NEC
®
Class 1 wiring.
• Consult applicable national and local
codes for compliance.
• Lutron recommends using two different
colours for D1 and D2 (DALI
bus) wires.
This will prevent wiring mistakes in
junction boxes where several different
DALI
bus
wires combine. Use the
following instructions for wiring the DALI
bus.
• Each DALI
link can have only 1
GRAFIK
Eye
QS with DALI connected to it. No
additional DALI bus supplies can be on
the link.
• Up to 64 DALI devices can be connected
to the DALI
link.
• No other devices may be connected to
the DALI
link.
WARNING! Shock hazard.
May result in serious injury or
death.
Do not wire live. Interrupt
power via circuit breaker before
wiring and servicing the DALI bus
supply.
Step 1:
Use the wire size chart at right to
determine which wire size to use based
on the length of the DALI
bus.
Step 2:
Wire the DALI
bus from terminal
D1 and terminal D2 to all DALI devices.
Step 3:
Separate DALI wiring from the
mains wiring. If wiring the DALI
bus as
PELV (Class 2: USA), maintain proper
separation from mains and NEC
®
Class 1
wiring.
Step 4:
Turn on circuit breaker to
energise.
