Overview
The DA-820 computers are x86 platforms in a standard, 19-inch, 3U rack-mountable housing, with 2 VGA
outputs, 4 Gigabit Ethernet ports, an internal CFast socket for OS storage, 2 RS-232/422/485 serial ports, and
6 USB ports.
With dual power supplies, 4 SDD/HDD slots, and a native PRP/HSR expansion module with specialized
middleware, the DA-820 computers are designed for a wide variety of industrial automation applications to
achieve maximum availability. In addition, the DA-820 computers comply with the IEC 61850-3 and IEC 60255
standards, guaranteeing system stability and reliability when used in a power industry application. As an added
value, the DA-820 features a modular design with standard PCI and PCIe interfaces for tremendous integration
and expansion flexibility. Users can add a variety of communication modules or graphics card to any of the 2
PCI slots, 3 PCIe x1 slots, and 1 PCIe x16 slot.
Wide temperature models of the DA-820 operate reliably in a -40 to 75°C operating temperature range with a
high performance dual-core processor, offering an optimal solution for applications subjected to harsh
environmental conditions.
The DA-820 is compliant with the IEC 60255 standard, which covers the protection of electrical relays in a
smart substation. IEC 60255 is one of the most widely used standards for testing relays and protection
equipment, and compliance ensures that the DA-820 will work reliably and seamlessly with IEDs (intelligent
electronic devices) as a part of robust substation automation system.

Wiring Requirements
The following common safety precautions should be observed before installing any electronic device:
•Power wires and communication/signal wires should be routed through separate paths. If power and
communication/signal wires must cross paths, make sure the wires are perpendicular at the intersection
point.
NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
•Use the type of signal transmitted through a wire to determine which wires should be bundled together and
which kept separate. The rule of thumb is that wiring that carries similar electrical signals can be bundled
together.
•When necessary, we strongly advise labeling the wiring for all devices in the system.
ATTENTION
Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid interference,
wires with different signal characteristics should be routed separately.
ATTENTION
Safety First!
Be sure to disconnect the power
cord before installing and/or wiring your device.
Electrical Current Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size.
If the current
goes above the maximum rating, the wiring could overheat, causing serious damage to your
equipment.
Temperature Caution!
Be
careful when handling the unit. When the unit is
plugged in, the internal components generate heat, and
consequently the
outer casing may feel hot to the touch.
Connecting the Power
To power on the DA-820 embedded computer, connect the power line to the DA-820’s power connector
(located on the right side of the rear panel) using the power cord shipped with the product, and then turn on
the power switch. If the power is properly supplied, the Power LED will light up first, and then the Storage LED
will start blinking when the Flash Disk Module is accessed during boot up. It takes about 30 to 60 seconds for
the operating system to boot up.

Wiring the Power Inputs
Refer to the following diagrams and table for a detailed description of the power input wiring. The terminal
numbers referred to in the table are shown in the leftmost diagram below.
Terminal Number Description Note
1 PWR1 Line PWR1 Line (+)
is connected to the Line terminal for the AC
power source.
2 PWR1 Neutral PWR1 Neutral (–) is connected to the Neutral terminal for
the AC power source.
3 PWR1 Surge Ground
PWR1 Surge Ground is connected to the Chassis Ground
via a jumper on the terminal block. Surge Ground is used as
the ground conductor for all surge and transient suppression
circuitry.
NOTE: Surge Ground must be disconnected from Chassis
Ground during HIPOT (dielectric strength) testing.
4 Chassis Ground
Chassis Ground
is connected to the Safety Ground terminal
for AC inputs. Chassis ground connects to both power supply
surge grounds via a removable jumper.
5 Relay COM port
6 Relay Open
7 Chassis Ground
Chassis Ground is connected to the Safety Ground
terminal
for AC inputs. Chassis ground connects to both power supply
surge grounds via a removable jumper.
8 PWR2 Surge Ground
PWR2 Surge Ground is connected to the Chassis Ground via
a jumper on the terminal block. Surge Ground is used as the
ground conductor for all surge and transient suppression
circuitry. NOTE: Surge Ground must be disconnected from
Chassis Ground during HIPOT (dielectric strength) testing.
9 PWR2 Line PWR2 Line (+)
is connected to the Line terminal for the AC
power source.
10 PWR2 Neutral PWR2 Neutral (-) is connected to the Neutral terminal for
the AC power source.

For AC Power Input
1. PWR1 Line should be connected to AC (Line).
2. PWR1 Neutral should be connected to AC (Neutral).
3. Surge Ground is connected to the Chassis Ground via a braided cable or other appropriate grounding wire.
Surge Ground is used as the ground conductor for all surge and transient suppression circuitry internal to
the protection board.
4. Chassis Ground should be connected to the AC Ground terminal.

ATTENTION
1. Equipment must be installed according to the applicable country wiring codes.
2.
Surge Ground MUST be disconnected from the Chassis Ground during HIPOT (dielectric strength) testing.
3. All line-to-
ground transient energy is shunted to the Surge Ground terminal. In cases where users require
the inputs to be isolated from the ground,
remove the ground braid between Surge and Chassis Ground.
Note that all line-to-ground transient protection circuitry will be disabled.

DA-820 Series Hardware Installation
2-9
HIPOT (Dielectric Strength) Testing
Before performing the HIPOT test, you MUST
remove
the jumpers and disconnect the
braided ground cable. Doing so can prevent
the transient/surge suppression circuitry
(
which is connected to Surge Ground)
from
being activated during the HIPOT test.
When finished, press the Power Switch button to start the system. It will take about 30 to 60 seconds for your
operating system to boot up.

DA-820 Series Hardware Installation
2-10
Reset Button
Pressing the Reset button initiates a hardware warm reboot. The button plays the same role as a desktop PC’s
reset button. After pressing the reset button, the system will reboot automatically. During normal use, you
should NOT use the Reset Button. You should only use this button if the software is not working properly. To
protect the integrity of data being transmitted or processed, you should always reset the system from the
operating system with the software reboot function.
