March 2021 Quick Start Guide
1 About this guide
This guide provides basic guidelines for Rosemount 0065 and 0185 Sensor
models. It does not provide instructions for configuration, diagnostics,
maintenance, service, troubleshooting, Explosion-proof, Flameproof, or
intrinsically safe (I.S.) installations.
If the Rosemount 0065 and 0185 ordered was assembled to a temperature
transmitter, see the appropriate Quick Start Guide for information on
configuration and hazardous locations certifications.
1.1 Safety Messages
WARNING
Explosions could result in death or serious injury.
Installation of this transmitter in an explosive environment must be in
accordance with the 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.
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.

Note
For 3-wire systems use one white and two red leads. Do not connect the
white leads. Insulate or terminate the unused white lead in a manner that
prevents shorting to the ground. For 2-wire systems, connect both sets of
leads.
