Installation
• Installation shall only be performed by qualified personnel and in accordance with local
governing regulations.
• Do not route cable openly; instead run cable separately in a grounded metal conduit to
protect it from ambient electrical noise.
• Seal all thread connections to prevent the ingress of moisture.
• Do not run cable near high voltage or current runs, contactors or SCR control drives.
• For pressure tight applications, install transducers hand tight plus ½ turn to 1½ turns.
PTFE tape or other appropriate sealant may be used to aid in sealing the threads for use
in pressure applications.
WARNING:
Improper installation may result in loss of process pressure.
