Installation
Connect Power
Display and non-display computers have a DC input terminal block for
connection to an 18…32V DC power source.
Operate the computer in an industrial or control room environment, which uses
some form of power isolation from the public low-voltage mains.
The DC power option supports operation from safety extra-low voltage (SELV)
power source.
The power supply is internally protected against reverse polarity.
Follow these steps to connect the computer to a DC power source.
1.
Turn off the main power switch or breaker.
2.
Verify that the DC power wires meet these requirements:
–
Material: Stranded copper
–
Wire gauge: 0.823…2.08 mm
(18…14 AWG)
ATTENTION:
When you connect power to the computer for the first time, the
following actions occur:
•
The default BIOS setting automatically starts the computer after it is plugged
into a power source.
•
You must read and accept an End User Setup procedure for computers with a
Windows operating system.
Do not disconnect power from the system until after the Windows Setup
procedure is completed. Disconnected power during this procedure can result
in a corrupted system image.
ATTENTION:
Supply the computer circuit with its own disconnect. Use an
uninterruptible power source (UPS) to help protect against unexpected power
failure or power surges.
Always shut down the Windows operating system before you disconnect power to
the computer to minimize performance degradation and operating system failures.
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.
IMPORTANT
A functional ground connection is required for EMC compliance.
