To maintain hazardous location certifications, you can only replace components in the
field with the exact same part so that the model string on the data plate remains correct.
This means you cannot add any hardware not reflected in the model string or upgrade a
hardware component to a newer version; any such upgrades are prohibited and void the
hazardous location certification.
For a list of user serviceable parts contact your Emerson Remote Automation Solutions
sales representative or Emerson Impact Partner.
This chapter describes the service tasks that everyone needs to know such as replacing
batteries or installing a firmware upgrade. A separate series of field replacement guides
covers major field replaceable components.
Any replacement not covered in this chapter or in the field replacement guides (such as
adding or upgrading hardware or replacing sensors) can only be performed at an
Emerson-authorized repair facility.
Important
Use only batteries supplied with the flow computer or sold by Emerson as spare parts for
this flow computer. If you substitute a battery you obtain elsewhere you will void your
certification unless it is the identical part from the same manufacturer as that supplied
with the flow computer from Emerson.
