Energy Management System
Energy Control Unit
Wiring and Installation Manual
The Energy Control Unit (ECU) is a gateway that
interfaces to both IT equipment (servers, LAN, etc) and
field bus devices (luminaire controllers, sensors, wall
switches, etc). Communication with IT equipment and
other ECUs is achieved using the Ethernet port.
Additionally, two USB 2.0 ports are provided for data
transfer and back-up purposes.
The ECU provides operating power together with
communication signals via GreenBus IITM to the various
field bus devices of the system via eight GreenBus IITM communication channels.
The ECU makes each device addressable via GreenBus IITM (e.g. each light fixture can be individually dimmed and
turned on/off). Devices will obtain their addresses during the commissioning process and no actions are required
during installation.
The following model(s) are available:
Indoor Locations:
EN-ECU-G4-P3D
Important Safeguards
When using electrical equipment, basic safety precautions should always be followed including the following:
• READ AND FOLLOW ALL SAFETY INSTRUCTIONS.
• Do not let power supply cords touch hot surfaces.
• Do not mount near gas or electric heaters.
• Equipment should be mounted in locations and at heights where it will not readily be subjected to tampering by
unauthorized personnel.
• The use of accessory equipment is not recommended by OSRAM Sylvania as it may cause an unsafe condition.
• Do not use this equipment for other than the intended use.

GreenBus II™ Wiring
Communication Circuit (24VDC, Class 2)
GreenBus IITM is a low-cost, high reliability communication means to report sensor and wall switch information back
to the ENCELIUM Energy Management System and to obtain optimum brightness settings for each individual light
fixture from the system – optimized to result in minimum energy costs for any given building.
The GreenBus IITM wiring originates at an Energy
Control Unit (ECU) and propagates in a daisy-chain
or “T” fashion from module to module (or other
compatible equipment).
GreenBus IITM uses proprietary connectors and jacks for ease of installation only.
Maximum 100 total devices
GreenBus IITM is a proprietary standard. Connect to ENCELIUM Energy Management System only. Do not
connect to other circuits.
Connect to ENCELIUM Energy Management System only. Do not connect to other circuits.
GreenBus IITM must be laid out as per ENCELIUM EMS supplied drawing. If changes are required, determine an
optimum wiring path utilizing the supplied prefabricated cables, based on the position of light fixtures and sensors.
As the modules obtain power via the GreenBus IITM, the number of modules on each chain is limited. It is suggested
to leave room for future system upgrades and to limit the number of modules per chain to 100 units during initial
installation.
Energy Control Unit Installation
The output channels of the Energy Control Unit are Class 2 circuits.
To reduce the risk of electric shock, the power supply for the equipment has a grounding type plug that has a
third (grounding) pin. This plug will only fit into a grounding type outlet. If the plug does not fit into the outlet,
contact a qualified electrician to install the proper outlet. Do not change the plug in any way.
Use only the power supply provided for this equipment. Damage or adverse functionality may occur if a
different power supply is used. If a replacement power supply is needed, please contact OSRAM Sylvania
Inc. Do not modify the power supply cable or connector.
The Energy Control Unit is intended for mounting in an electrical room where access will be by authorized
personnel only.
