Safety messages
NOTICE
This guide provides basic guidelines for Rosemount™ 214A2A Sensor models.
Complications can arise if sensors are assembled to transmitters that have different, but compatible
approval option codes. Be aware of the following situations:
• If an I.S. approved sensor is ordered with a housing, a transmitter enclosed in that housing may
have a different I.S. approval rating. Refer to the transmitter IS certificate if applicable.
• If a sensor and transmitter have different certifications, or if either has more certifications than the
other, installation must comply with the most restrictive requirements required by either
component. This is especially (but not exclusively) relevant when combination approvals are
ordered on either the sensor or transmitter. Review certifications on both the sensor and
transmitter for installation requirements and ensure installation of the sensor/transmitter
assembly complies with a single certification that is shared by both of these components and that
meets the requirements of the application.
WARNING
Explosions
Explosions could result in death or serious injury.
Installation of sensor in an explosive environment must be in accordance with appropriate local,
national, and international standards, codes, and practices.
Conduit/cable entries
Unless marked, the conduit/cable entries in the housing use a ½–14 NPT thread form. Entries
marked “M20” are M20 × 1.5 thread form. On devices with multiple conduit entries, all entries will
have the same thread form. Only use plugs, adapters, glands, or conduit with a compatible thread
form when closing these entries.
When installing in a hazardous location, use only appropriately listed or Ex certified plugs, glands,
or adapters in cable/conduit entries.
Only use plugs, adapters, glands, or conduit with a compatible thread form when closing these
entries.
Physical access
Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end
users’ equipment. This could be intentional or unintentional and needs to be protected against.
Physical security is an important part of any security program and fundamental to protecting your
system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for
all systems used within the facility.

Figure 1-1: RTD Lead Wire Configuration per IEC 60751 - Single Element
2-wire 3-wire 4-wire
Note
To configure a single element, 4-wire RTD as a 3-wire system, connect only
one white lead. Insulate or terminate the unused white lead in a manner that
prevents shorting to the ground. To configure a single element, 4-wire RTD
as a 2-wire system, connect matching colored wires first and then connect
the paired wires to the terminal.

The process side of the assembly is for the responsibility of the user. The
assembly should always be used in a closed system.
No changes are allowed on the product.
Flameproof enclosure “d”;
In type of explosion protection Ex d, certified entry devices shall be used that
are suitable for the application and correctly installed.
Unused openings shall be closed by suitable blanking elements. Only
suitable thread adapters shall be used. Thread adapters will not be used in
combination with blanking elements.
Verify the entry size (M20, ½-in. ¾-in., etc).
The degree of protection of IP66 or IP67 to EN 60529 is only achieved if
certified Ex d entry devices are used that are suitable for the application and
correctly installed.
Only use approved inserts.
For external earthing or bonding connection of the connection head a cable
lug shall be used so that the conductor is secured against loosening and
twisting and that contact pressure is permanently secured.
