9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 andcommunication/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 ones should be kept separate. The rule of thumb is that wiring that carries similar electricalsignals 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 yourequipment.
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.

Restricted Access Location
This equipment is intended to be used in Restricted Access Locations, such as a computer room, withaccess limited to SERVICE PERSONAL or USERS who have been instructed on how to handle the metal
chassis of equipment that is so hot that special protection may be needed before touching it. The location
should only be accessible with a key or through a security identity system.
External metal parts of this equipment are extremely hot!! Before touching the equipment,
you must take special precautions to protect your hands and body from serious injury.

DA-680 Series Hardware User Manual10Connecting the PowerThe DA-680 Series includes single-power and dual-power models that use terminal block(s) located on therear panel. Connect the power cord wires to the screws on the power input and then tighten the screws. The
Power LED will light up to indicate that power is being supplied to the DA-680, after which the BIOS will
initialize the flash disk module, causing the Storage LED to blink. It should then take about 30 to 60
seconds for the operating system to complete the boot-up process.

Wiring the Power Inputs
Refer to the following illustration and table for details on wiring the power inputs to the DA-680 computer.
The table uses the reference numbers in the diagram to identify the lines in the terminal blocks.

Upgrading the BIOS
This section describes how to upgrade the BIOS on your computer.

NOTE
Incorrect BIOS updates may permanently damage the computer. We strongly recommend that you contact
the Moxa technical support team for assistance to obtain all the necessary tools and the most current
information before attempting to upgrade the BIOS on any Moxa device.

2.

Right click on the USB disk and select Format.

3.

Select FAT32 for the File System and click OK to start formatting the USB disk.

Step 2: Prepare the Upgrade File
You must use the BIOS upgrade installation file to upgrade the BIOS. Contact Moxa’s technical department
for assistance.
1.

Get the BIOS upgrade file (includes an efi folder and an xxxx.efi file)2.

Copy the efi folder and xxxx.efi file to the bootable USB disk.

Step 3: Run the Upgrade Program on the Computer
1.

Reboot the computer from the USB device and press F2 while it is booting up to go to the Boot
Manager.
If the BIOS does not recognize the USB device as the boot device, the USB device may not have apartition table. Use the Windows command line tool diskpart to rebuild the partition table.

2.

Select the USB disk to boot from.

3.

In the SHELL environment console, type fs0:, then go to the directory where the upgrade file is locatedand type xxxxxx.efi (the name of the file is based on the upgrade file you get from Moxa).

4.

The upgrade program will run automatically. Wait for the process to complete.

5.

When the upgrade is finished, the computer will automatically reboot.
You can check the BIOS version on the Main page

If the system has more than one boot device, you will see more than one fsx (x represents the numberof devices).

6.

Access each device path fsx (x is the device index), then type ls to view the content of the boot device
until you located the upgrade file and run it.

ATTENTIONDo NOT switch off the power supply to the computer during the BIOS upgrade, since doing so may cause
the system to crash.

A. Safety Installation Instructions

A. RTC Battery Warning

ATTENTION
There is a risk of explosion if the wrong type of battery is used. To avoid this potential danger, always be
sure to use the correct type of battery. Contact the Moxa RMA service team if you need to replace yourbattery.
Caution
There is a risk of explosion if the battery is replaced by an incorrect type. Dispose of used batteries
according to the instructions on the battery.

B. Fuse Warning
CAUTION: For continued protection against fire, replace only with the same type and rating of fuse.

C. Rack-mounting Warning
The following or similar rack-mounting instructions are included with the installation instructions:(1) Elevated Operating Ambient: If installed in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be greater than the room ambient temperature.
Therefore, consideration should be given to installing the equipment in an environment compatible with the
maximum ambient temperature (Tma) specified by the manufacturer.
(2) Reduced Air Flow: Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
(3) Mechanical Loading: Mounting of the equipment in the rack should be such that a hazardous condition
is not achieved due to uneven mechanical loading.
(4) Circuit Overloading: Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits might have on overcurrent protection and supply
wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing thisconcern.
(5) Reliable Grounding: Reliable grounding of rack-mounted equipment should be maintained. Particularattention should be given to supply connections other than direct connections to the branch circuit (e.g., byusing power strips).
