Upgrading System Firmware
In order 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.
This chapter describes the service tasks that everyone needs to know such as replacing batteries or
installing a firmware upgrade. For other field replacements, see the appropriate field replacement
guides for that component. Any replacement not covered in this chapter or in the field
replacement guides can only be performed at an Emerson-authorized repair facility.
Important
Use only batteries supplied with the flow computer or sold by Emerson Remote Automation
Solutions 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.
