Chapter 2 Install the Panel PC
Connect DC Power
Operate the panel PC in an industrial or control room environment, which
uses some form of power isolation from the public, low-voltage mains.
All VersaView DC powered models require a safety extra low voltage (SELV)
power supply. The power supply is internally protected against reverse
polarity.
To minimize ground loop currents and noise, Allen-Bradley recommends that
DC powered models use only one grounded connection. See
Figure 1 on
page 10 for the ground connection on these models.
Follow these steps to connect the computer to a DC power source.
Install the DC Power Connector Assembly
This connector assembly provides strain relief for the DC power wires by
reducing their movement. To assemble and attach the connector assembly,
perform the following steps.
1. Remove the DC terminal block from the computer chassis.
2. Open the power connector assembly kit that ships with the computer
(A on page 20 ).
3. Insert the cable tie through the slots of the appropriate connector half
(B on page 20 ).
4. Strip the end of each DC power wire to the length in Table 1 on page 20 .
5. Insert each stripped end into the DC terminal block as shown in
Table 1 on page 20 .
ATTENTION: When you connect power to the 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 6300P panel PCs with a Microsoft 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: For VersaView 6300P panel PCs with a Windows OS, perform the
following:
• Supply the computer 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 OS before you disconnect power to the computer to
minimize performance degradation and operating system failures.
You need the following tools for this installation:
• Adjustable torque screwdriver with M2 and M3 flat-blade screw bits
• Wire stripper, cutter, and crimper tool
• Cutting pliers
IMPORTANT DC power wires must be of stranded copper, certified for at least 85 °C
operation, and sized according to Table 1 on page 20 .
IMPORTANT The DC terminal block in the photos is only for illustrative purposes.
Your DC terminal block can differ in size, shape, and color to what is
shown in the photos.
