Connecting AC power
A standard IEC 320 power cord provides power to the VersaView Integrated Display
Computer. The power supply input will accept 120/240V AC. The power supply is
autoswitching. Ensure that sufficient power is available.
Connecting to a network
The VersaView Integrated Display Computer accommodates CAT5 twisted pair Ethernet
cabling with RJ45 connectors to support 100 Mbps network data transfer.
Select an electrical outlet carefully before plugging in your computer:
The power cord must be connected to an outlet having an earth ground (three-prong outlet).
Failure to follow this warning could result in severe electrical shock.
Installing computer in a panel, enclosure or rack that is already connected to earth ground will
satisfy this requirement. Otherwise, connect your computer to earth ground using a 16 AWG or
larger external wire.
The ground wire should have green insulation with a yellow stripe for easy identification.
The outlet should have its own disconnect. Do not plug the computer into an outlet that is
connected to the main electrical disconnect.
To prevent problems resulting from power surges or unexpected power failure, protect the outlet
with its own fuses or circuit breakers, as well as an Uninterrupted Power Supply (UPS) system.
Always shut down the operating system prior to removing power. Failure to do so will cause
performance degradation and eventual failures in the operating system.
Performance degradation of your Ethernet communications is likely to result if the unit or cables
are subjected to extreme radiated or conducted high-frequency noise. It is the user’s
responsibility to properly route cables and condition input power in order to improve
communication reliability. Proper cable routing and power conditioning is required to ensure
reliable Ethernet communications in industrial environments. Rockwell Automation recommends
that all Ethernet cabling be routed through dedicated metal conduits. Installing ferrite bead filters
at cable ends may also improve reliability.
