DALI Bus Wiring Details

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.

QS with DALI:
®
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
wiring.
Step 4: Turn on circuit breaker to
energise.

Wiring Size and Bus Length
DALI bus wires D1 and D2 are not
polarity sensitive. DALI bus length is
limited by the wire gauge used for D1 and
D2 as follows:
