EcoSystem Bus Wiring Details

EcoSystem bus wiring may be considered
NEC Class 1 or IEC PELV/NEC
®
Class 2.
• NEC Class 1: EcoSystem bus wiring
®
may be run in the same conduit as mains
voltage wiring to fixtures.
• IEC PELV/NEC Class 2: EcoSystem 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
colors for E1 and E2 (EcoSystem bus)
wires. This will prevent wiring mistakes
in junction boxes where several different
EcoSystem bus wires combine. Use
the following instructions for wiring the
EcoSystem bus.
• Each EcoSystem link can have only 1
GRAFIK Eye QS with EcoSystem control
unit connected to it. No additional
EcoSystem bus supplies can be on the
link.
• Up to 64 EcoSystem devices can be
connected to the EcoSystem link.
• No other devices may be connected to
the EcoSystem 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 EcoSystem bus
supply.
®
Step 1: Use the wire size chart at right to
determine which wire size to use based
®
on the length of the EcoSystem bus.
Step 2: Wire the EcoSystem bus from
terminal E1 and terminal E2 to all
EcoSystem devices.
Step 3: If wiring the EcoSystem bus as
IEC PELV/NEC
separation from mains and NEC
wiring.
Step 4: Turn on circuit breaker to
energize.

Wiring Size and Bus Length
EcoSystem bus wires E1 and E2 are not
polarity sensitive. EcoSystem bus length
is limited by the wire gauge used for E1
and E2 as follows:
Wire Gauge Maximum EcoSystem
Bus Length
12 AWG 2200 ft (671 m)
(4.0 mm )
2
14 AWG 1400 ft (427 m)
(2.5 mm )
2
16 AWG 900 ft (275 m)
(1.5 mm )
2
18 AWG 570 ft (175 m)
(1.0 mm )

Note: Some EcoSystem devices
(ballasts, drivers, and interfaces)
accept connections to daylight
sensors and occupancy sensors.
For instructions on installing and
operating these devices, refer to
their individual instruction sheets.
EcoSystem bus wiring cables (16 AWG/
1.5 mm ) are available from Lutron, part
2
numbers C-CBL-216-GR-1 (non-plenum)
and C-PCBL-216-CL-1 (plenum).
