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 your equipment as specified in the Install section of this QSG 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 VOID YOUR WARRANTY. Look-alike
substitutions 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.

Sensor/process application compatibility
The wetted sensor materials may not be compatible with process composition and operating
conditions.
Application compatibility is entirely the operator's responsibility.
WARNING
Before removing the sensor, be absolutely certain the process pressure is reduced to 0 psig and the
process temperature is at a safe level.

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.
