3.1 Anti-static Precautions
WARNING:
Failure to take ESD precautions during the maintenance of the EP
series may result in permanent damage to the EP series and severe
injury to the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the UPC-V312-D525. Dry climates are especially susceptible to ESD. It is
therefore critical that whenever the UPC-V312-D525 is accessed internally, or any other
electrical component is handled, the following anti-static precautions are strictly adhered
to.
UPC-V312-D525 Panel PC
Wear an anti-static wristband: - Wearing a simple anti-static wristband can
help to prevent ESD from damaging the board.
Self-grounding: - Before handling the board touch any grounded conducting
material. During the time the board is handled, frequently touch any
conducting materials that are connected to the ground.
Use an anti-static pad: - When configuring the UPC-V312-D525, place it on
an antic-static pad. This reduces the possibility of ESD damaging the
UPC-V312-D525.
Only handle the edges of the PCB: - When handling the PCB, hold the PCB
by the edges.
3.2 Installation Precautions
When installing the panel PC, please follow the precautions listed below:
Power turned off: When installing the panel PC, make sure the power is off.
Failing to turn off the power may cause severe injury to the body and/or
damage to the system.
Certified Engineers: Only certified engineers should install and modify
onboard functionalities.
Anti-static Discharge: If a user open the rear panel of the panel PC, to

3.5 Mounting the System
WARNING:
When mounting the panel PC onto an arm or onto the wall, it is better
to have more than one person to help with the installation to make sure
the panel PC does not fall down and get damaged.
The panel PC is VESA (Video Electronics Standards Association) compliant and can be
mounted on an arm, a stand or a bracket with a 100 mm/75 mm interface pad. M8 and M4
mounting screws can both be used for VESA mount. The VESA mount retention screw
holes of the UPC-V312-D525 are shown in
Figure 3-3.

3.7 Redundant Power
The UPC-V312-D525 is a system that supports redundant power. The redundant power
input increases the reliability of the system while preventing data loss and system
corruption from sudden power failure. The system can instantly and uninterruptedly switch
to the second power input when the main power is unavailable or in low voltage capacity.
There are two power connectors on the bottom panel. Power 1 connector is a 3-pin
terminal block that supports ACC On signal. Power 2 connector is a DIN connector that
can directly connect to a power adapter. The supported power input voltages are:
Power 1 (T erminal block): 9 V (+/-3 V) ~ 36 V
Power 2 (DC jack): 10.5 V (+/-0.3 V) ~ 36 V
UPC-V312-D525 Panel PC
Figure 3-30: Power Connectors
When the system is in ACC On mode, the main power input is from the Power 1 connector.
When the system is in ACC Off mode, the main power input is from the Power 2 connector.
The ACC on/off mode is selected by the ACC on/off switch on the bottom panel.
(
Figure 3-16).
The following sections describe how redundant power works in ACC On mode and ACC
Off mode.

3.7.1 ACC ON
NOTE:
In ACC On mode, the Power 1 connector must connect to the ACC on
signal to be able to control system power.
The ACC On mode is designed for vehicle applications. When the UPC-V312-D525 is in
ACC On mode, the main power input is the Power 1 connector and the backup power is
from the Power 2 connector.
3.7.1.1 Boot-up
When both power connectors are connected to the power source with over 9 V, the two
power LEDs on the front panel remain off until the ACC ON signal jumps from low to
high. The user can choose AT power mode or ATX power mode to control the system.
The following flow diagrams show the boot-up process and the LED status in AT and ATX
power modes.
