1 About this guide
This guide provides basic guidelines for Rosemount 214C Sensor models. If
the sensor was ordered assembled to a temperature thermowell or
transmitter, see the appropriate product literature for information on
configuration and hazardous locations certifications.
1.1 Safety messages
NOTICE
Complications can arise when the sensors and the transmitters to which they
are assembled are certified to compatible, but each has different approvals.
Be aware of the following situations:
• If an I.S. approved Rosemount 214C 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
Explosion
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.

Quick Start Guide May 2021
WARNING
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.
CAUTION
Refer to Product Certification section of this Quick Start Guide
documentation.

Figure 2-1: RTD Lead Wire Configuration per IEC 60751 - Single Element
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.
