Install the Thin Client or Computer Chapter 3
Connect Power VersaView 5000 thin clients and industrial computers are factory shipped to be
connected to a 24V DC power source, except for the 6200T-BA VersaView
ThinManager thin client model, which uses an included AC to 5V DC
adapter. For applications with an AC power source, see
AC Power Options on
page 31 .
Operate the VersaView thin client or industrial computer in an industrial or
control room environment, which uses some form of power isolation from the
public low-voltage mains.
Connect DC Power
DC power models support operation from a SELV
(1)
power source. The DC
common (DC-) can be connected together to the functional ground screw to
support some SELV cases where grounding at the computer is required by the
end user.
The power supply is internally protected against reverse polarity.
ATTENTION: When you connect power to the thin client or computer for the
first time, these actions occur:
• The default UEFI setting automatically starts the computer after it is plugged
into a power source.
• For VersaView 5400 industrial computers with a Windows operating system
(OS), you must read and accept an End User Setup procedure.
Do not disconnect power from the system until after the Windows Setup
procedure is completed. If power is disconnected during this procedure, it
can result in a corrupted system image.
ATTENTION: Supply the thin client or computer circuit with its own disconnect.
Use an uninterruptible power source (UPS) to help protect against unexpected
power failure or power surges.
For VersaView 5400 industrial computers, always shut down the Windows OS
before you disconnect power to the computer to minimize performance
degradation and operating system failures.
(1) Where safety extra low voltage (SELV) is as defined in IEC 61010-2-201.
IMPORTANT This section does not apply to the cat. no. 6200T-BA thin client single display
model, which is supplied with an AC to 5V DC power adapter and cord.
ATTENTION: Use a SELV isolated and ungrounded power supply as input
power to the computer. This power source provides protection so that under
normal and single fault conditions, the voltage between the conductors and
Functional Earth/Protective Earth does not exceed a safe value.
