Product Warranty (2 years)
Advantech warrants the original purchaser that each of its products will be free from
defects in materials and workmanship for two years from the date of purchase.
This warranty does not apply to any products that have been repaired or altered by
persons other than repair personnel authorized by Advantech, or products that have
been subject to misuse, abuse, accident, or improper installation. Advantech
assumes no liability under the terms of this warranty as a consequence of such
events.
Because of Advantech’s high quality-control standards and rigorous testing, most
customers never need to use our repair service. If an Advantech product is defective,
it will be repaired or replaced free of charge during the warranty period. For out-of-
warranty repairs, customers will be billed according to the cost of replacement mate-
rials, service time, and freight. Please consult your dealer for more details.
If you believe your product to be defective, follow the steps outlined below.
1. Collect all the information about the problem encountered. (For example, CPU
speed, Advantech products used, other hardware and software used, etc.) Note
anything abnormal and list any onscreen messages displayed when the prob-
lem occurs.
2. Call your dealer and describe the problem. Please have your manual, product,
and any helpful information readily available.
3. If your product is diagnosed as defective, obtain a return merchandise authori-
zation (RMA) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a completed Repair and Replacement
Order Card, and a proof of purchase date (such as a photocopy of your sales
receipt) into a shippable container. Products returned without a proof of pur-
chase date are not eligible for warranty service.
5. Write the RMA number clearly on the outside of the package and ship the pack-
age prepaid to your dealer.

Declaration of Conformity
CE
This product has passed the CE test for environmental specifications when shielded
cables are used for external wiring. We recommend the use of shielded cables. This
type of cable is available from Advantech. Please contact your local supplier for
ordering information.
Test conditions for passing also include the equipment being operated within an
industrial enclosure. In order to protect the product from damage caused by electro-
static discharge (ESD) and EMI leakage, we strongly recommend the use of CE-
compliant industrial enclosure products.
FCC Class A
This equipment has been tested and found to comply with the limits for a Class A dig-
ital device, pursuant to part 15 of the FCC Rules. These limits are designed to pro-
vide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Opera-
tion of this equipment in a residential area is likely to cause harmful interference. In
this event, users are required to correct the interference at their own expense.

ECU-4784 User Manual 2
1.1 Introduction
Based on IEC 61850-3, a standard for the design of electrical substation automation,
which defines communication between all Intelligent Electronic Devices (IED) and
other related equipment from the process level (data acquisition, sensors and actua-
tors) to the bay level (protection, monitoring and control tasks) and up to the station
level (HMI/SCADA). Advantech’s ECU-4784 Series can operate as a smart substa-
tion station level communication server, a HMI/SCADA workstation, a remote control
station, a cyber security server, and an environment status monitoring station. Sys-
tem integrators can thereby design an optimized digital substation while allowing
energy operators to deliver electricity which is more secure, reliable, economical, and
efficient.
Advantech’s ECU-4784 Series are certified by IEC 61850-3 and IEEE 1613 to meet
the harsh and critical requirements in smart grid automation. It provides high perfor-
mance and reliable functionality to meet the most critical computing applications and
reduces project deployment and maintenance costs. It supports remote monitoring
and diagnosis for remote device connectivity to enhance management and mainte-
nance efficiency. It is easy to expand domain I/O with its modular design, and pro-
tects the system to meet the critical security application requirements.
High-performance Computing Platforms for Power and Energy Automation
Applications
High computing performance processors to meet the most critical computing
applications by VT-D, which can run multiple software application. Energy oper-
ators can leverage virtual machine (VM) resources on the ECU-4784 to reduce
project deployment cost.
Highly integrated all in one server platform to enhance smart substation station
level project deployment efficiency by integrating HMI visualization, monitoring,
and control with data concentrator and protocol converter to finish all the station
level tasks. These functions would be implemented by the different data collec-
tion gateways and SCADA workstation.
Certification for Robust and Reliability System
IEC-61850-3 and IEEE 1613 certification stand for the highest reliability, which
are made to withstand vibration, electrical surges, fast transients, and extreme
temperatures.
ECU-4784 Series supportsTUV IEC 61850-3 and IEEE 1613 certification, ECU-
4784 has higher standard than other embedded automation controllers and con-
tributes to higher reliability and stability. This makes it suitable for any global
P&E automation market and harsh environments.
ECU-4784 Series is designed for applications in substations where it is sub-
jected to certain electric interference. Equipped with isolated power, isolated
communication ports, ECU-4784 Series has high resistance toward electrical
noise. It has been proved it can work well in substations but it is also suitable for
harsh applications.

Chapter 1 Overview
Easy to Diagnose System & Communication and Enhance Maintenance Effi-
ciency
Remotely monitor, diagnose and manage systems to provide high system main-
tenance efficiency. Use AMT (built in remote KVM) to quickly access a remote
device’s desktop for diagnosis and troubleshooting without on-site technical
support.
Easy to expand domain I/O by functional modules and enhance maintenance
efficiency
Combined with two domain I/O slots to bring more flexible industrial application
for customers to extend more rich data collection and variety.
Integrated functional module design is convenient for wiring, installing and main-
taining.

1.5 Safety Precautions
The following messages inform the details of making a connection. In most cases,
you will simply need to connect a standard cable.
Warning! Always disconnect the power cord from your chassis whenever you are
working on it. Do not connect while the power is on. A sudden rush of
power can damage sensitive electronic components. Only experienced
electronics personnel should open the chassis.
Caution! Always ground yourself to remove any static electric charge before
touching ECU-4784 Series Modern electronic devices are very sensitive
to static electric charges. Use a grounding wrist strap at all times. Place
all electronic components on a static-dissipative surface or in a static-
shielded bag.
Note! If DC voltage is supplied by an external circuit, please put a protection
device in the power supply input port.
