OUNDATION
1. Apply two complete turns of sealing tape to the manifold threads
(with the open end of the threads pointing toward you, wrap the
tape clockwise beginning at the edge closest to you).
2. Turn the manfiold threads into the sensor module to leak tight.
Commissioning (Paper) Tag
When commissioning more than one device on a fieldbus segment, it
can be difficult to identify which device is at a particular location. A
removable tag provided with the transmitter can aid in this process by
linking the Device ID and a physical location. TheDevice ID is a unique
code that identifies a particular device in the absence of a device tag.
The device tag is used by the customer as an operational identification
for the device and is usually defined by the Piping and Instrumentation
Diagram (P & ID).
The installer should note the physical location in both places on the
removable commissioning tag and tear off the bottom portion. This
should be done for each device on the segment. The bottom portion of
the tags can be used for commissioning the segment in the control
system, providing a direct link between the Device ID and the tag
location.

Proper electrical installation is necessary to prevent errors due to
improper grounding and electrical noise. Shielded, twisted pair cable
should be used for best results in electrically noisy environments. Cable
Type A is recommended by F
The Model 3051 has an explosionproof housing and circuitry suitable
for intrinsically safe and non-incendive operation. Individual
transmitters are clearly marked with a tag indicating the certifications
they carry. See Appendix A: Specifications and Reference Data for
specific approval categories, and see Appendix B: Approvals for
installation drawings.
