Industrial Computers for Hazardous Locations
4.
Secure the ground wire to the functional ground screw by using a ring connector.
Tighten the functional ground screw to the computer at the torque value listed in the
table in
Installation Guidelines on page 8
.
5.
Apply 18…32V DC power to the computer.
Connect to a Network
The computers have two 1 Gb LAN ports. The computers connect to an Ethernet network by
using CAT5 or better twisted-pair Ethernet cable with RJ45 connectors.
IMPORTANT
When using the functional ground screw, connect the computer to earth ground by
using the wire gauge listed in the table in
Installation Guidelines on page 8
.
WARNING:
When you connect a LAN cable, verify that the cable is fully inserted in the LAN port
and the latch is engaged. Failure to do so could result in an electric arc that can cause an explosion
in a hazardous location.
IMPORTANT
To help prevent performance degradation of Ethernet communication, do not subject the
computer or cables to extreme radiation or conducted high-frequency noise.
In industrial environments, proper cable routing and power conditioning are required for
Ethernet communication. Rockwell Automation recommends that you route all Ethernet
cable through dedicated metal conduits. For improved performance reliability, install ferrite
bead filters at the cable ends.
