Process reference connection

The figures shown in this chapter illustrate process reference connections
only. Earth safety ground is also required as part of this installation, but is not
shown in the figures. Follow national, local, and plant electrical codes for
safety ground.

Use the Process reference options table to determine which process
reference option to follow for proper installation.
