Each Bus Supply CCI input may be configured as
normally open (NO) or normally closed (NC) (see OPT
Switches on page 8). Inputs may be dry contact closure or
open collector (NPN) with the following specifications:
• On-state saturation voltage less than 2.0 V
• Off-state leakage current less than 10 µA
• Minimum open circuit voltage rating 24 V
• Minimum current rating 10 mA

Contact Closure Input Wiring (if used)
Contact closures from a building automation system may
be wired directly to the EcoSystem Bus Supply.
Contact Closure Inputs on the EcoSystem Bus Supply
are programmed to control ballasts and modules through
the EcoSystem Programmer.
Use the following instructions to wire external contact
closure outputs to the EcoSystem Bus Supply. Distance
from contact closures to the EcoSystem Bus Supply is
limited to 200 feet (61 m). Wire may be #12 AWG to #22
AWG (2.5-0.5 mm
).

DO NOT WIRE LIVE! Interrupt power via circuit
breaker before wiring and servicing. V
PWR indicator is off when power is off.
A. Wire between the contact closure relay to CCI-1 (terminal
A) or CCI-2 (terminal B) and COM (terminal C) on the red
terminal.
I f using a 2L version, wire to the A or B terminal beneath
the bus terminal blocks you want to contact with that
CCI.
B. Turn on the circuit breaker to energize the EcoSystem
Bus Supply. V
PWR indicator on the EcoSystem Bus
Supply glows green when energized.
Contact closure inputs are PELV (Class 2: USA)
circuits and cannot be run with mains wiring.
Unless otherwise specified, the voltages do not
exceed 12-35 V
the requirements of NFPA 70, National Electric
Code (NEC
). Follow all applicable national and/or
®
local wiring regulations.
