EcoSystem C5-BMF-2A Ballast Module
3691013e 1 08.31.17
Fixture Mountable Ballast Module for
3-wire Fluorescent Ballasts
Lutron EcoSystem Ballast Module allows for
integration of Lutron 3-wire phase controlled
dimming ballasts into Lutron EcoSystem Bus
(Eco-10, Hi-lume Compact SE, and Hi-lume
series only). The Ballast Module combines digital
commands and sensor data to determine the proper
light level.
Features
Continuous, flicker-free dimming from 100% to
minimum ballast level, (10% for Eco-10, 5% for
Hi-lume Compact SE, and 1% for Hi-lume).
Powers and responds to one occupancy sensor,
one photo sensor, and one personal control input
(infrared receiver or wallstation).
Communicates status and sensor levels over the
EcoSystem Bus.
Universal voltage input: 120/240/277 V~ 50/60 Hz.
Non-volatile (EEPROM) memory stores specific
system information for 10 years from removing
power to restoring power.
100% performance-tested at factory.

Make sure that the supply breaker to the digital
ballast module is OFF when wiring.
Connect the four conductors to the four digital

Note: The digital ballast module accepts only one
IR Input. Use of the IR Input for the Daylight Sensor
precludes the use of an Infrared Receiver or keypad
with the attached digital ballast module.

Wire color designations of the sensor:
Red = +20 V-
Black = Common
White = IR Signal
Make sure that the supply breaker to the digital

of a keypad with this module and the IR output from
the Daylight Sensor for programming.

Low-Voltage Wiring (continued)
EcoSystem Bus Wiring
The EcoSystem Bus connects all ballasts together
and requires a Power Supply. Each EcoSystem Bus
can support a maximum of 64 Digital Ballasts or
Digital Ballast Modules. For integration of multiple
buses or other lighting control systems, please
contact a Lutron Representative.
Attention Electricians and Contractors
Regardless of bus wire gauge, ballast terminals
will hold only one 18 16 AWG (0.75 1.5 mm
2
)
solid wire. In most cases a wire connection to the
EcoSystem Bus is required.
Notes
E1 and E2 wires are not polarity sensitive.
Bus length is limited by the wire gauge used for
E1 and E2 as follows:
Wire Gauge Loop Length (max)
12 AWG (4.0 mm

) 2200 ft (828 m)
14 AWG (2.5 mm
