Essential instructions

Read this page before proceeding!

Emerson designs, manufactures, and tests its products to meet many national and international
standards. Because these instruments are sophisticated technical products, you must properly install,
use, and maintain them to ensure they continue to operate within their normal specifications. You
must adhere to the following instructions and integrate them into your safety program when
installing, using, and maintaining Emerson's Rosemount™ products. Failure to follow the proper
instructions may cause any one of the following situations to occur: loss of life, personal injury,
property damage, damage to this instrument, and warranty invalidation.

• Read all instructions prior to installing, operating, and servicing the product.

• If you do not understand any of the instructions, contact your Emerson representative for

clarification.

• Follow all warnings, cautions, and instructions marked on and supplied with the product.

• Inform and educate your personnel in the proper installation, operation, and maintenance of the

product.

• Install equipment as specified in the installation instructions of the appropriate Quick Start Guide

and per applicable local and national codes. Connect all products to the proper electrical and
pressure sources.

• To ensure proper performance, use qualified personnel to install, operate, update, program, and

maintain the product.

• When replacement parts are required, ensure that qualified people use replacement parts

specified by Emerson. Unauthorized parts and procedures can affect the product's performance,
place the safe operation of your process at risk, and may result in fire, electrical hazards, or
improper operation.

• Ensure that all equipment doors are closed and protective covers are in place, except when

maintenance is being performed by qualified people, to prevent electrical shock and personal
injury.

Note

The information contained in this document is subject to change without notice.

WARNING

Pressure and temperature

Before removing the sensor, be absolutely certain that the process pressure is reduced to 0 psig
and the process temperature is lowered to a safe level.

Do not insert or retract retractable sensors when process pressures are in excess of 64 psig (542
kPa) for option 21 or 35 psig (343 kPa) for option 25.

WARNING

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.
