2. Application Scheme
2.1 Transportation
Well-packaged products are suited for transportation by all kinds of vehicles. During
transportation, products should not be put in open cabin or carriage. During
transshipping, products should not be stored in open air without protection from the
atmospheric conditions. Products should not be transported together with inflammable,
explosive and corrosive substances and are not allowed to be exposed to rain, snow
and liquid substances and mechanical force.
2.2 Storage
Products should be stored in package box when it is not used. And warehouse
temperature should be 0°C ~ 40°C, and relative humidity should be 20% ~ 85%. In
the warehouse, there should be no harmful gas, inflammable, explosive products, and
corrosive chemical products, and strong mechanical vibration, shock and strong
magnetic field interference. The package box should be at least 10cm above ground,
and 50cm away from wall, thermal source, window and air inlet.
Caution!
Risk of destroying the device!
When shipping the PC in cold weather, please pay attention to the extreme
temperature variation. Under this circumstance, please make sure no water
drop (condensation) is formed on the surface or interior of the device. If
condensation is formed on the device, please wait for over twelve hours before
connecting the device.

3.1 Notices before Connection
Warning
The connected or built-in peripherals with opposite polarities are not allowed.
Warning
The device only operates when connecting with grounded power. No operation is
allowed when the device power is ungrounded or only impedance is grounded.
Warning
Rated voltage of the device in use shall be in accord with power feature of the
product.
Note:
Only the peripheral devices approved for industrial application can be used. When
operating the PC, hot swappable IO modules (USB) can be used. The IO devices
without hot swap function can only be connected when the PC is powered off.
3.2 Product Grounding
Low impedance ground connection is more helpful to release the interference
produced by the external cables, the signal cables or the cables connecting the IO
module to the grounding system.
Ground Terminals
The equipotential bonding terminal ①
on the device shall be connected with
the cabinet installed with the PC or the
central grounding busbar on the device.
The minimum cross section area of the
cable shall be no less than 5mm2, and
the maximum ground resistance shall be
no more than 0.1Ω.

Device Connection

3.3 Connecting the Device to Power
Steps to connect the device to power:
Connect the power adapter with
the power input connector ①,
then press the power switch
button on the front panel of the
PC to boot up the PC, and the
