Instructions and procedures in this section may require special precautions to ensure the safety of the personnel performing the operations. Information that potentially raises safety issues is indicated by a warning symbol (FOUNDATION FIELDBUS INFORMATION). Please refer to the following safety messages before performing an operation preceded by this symbol.

Failure to follow these installation guidelines could result in death or serious injury.

•Make sure only qualified personnel perform the installation.

Electrical shock could cause death or serious injury.

•If the device or sensors are installed in a high voltage environment and a fault condition or installation error occurs, high voltage may be present on transmitter leads and terminals.

•Use extreme caution when making contact with the leads and terminals.

FOUNDATION FIELDBUS INFORMATION

FOUNDATION fieldbus is an all-digital, serial, two-way, multidrop communication protocol that interconnects devices such as transmitters and valve controllers. It is a local area network (LAN) for instruments that enables basic control and I/O to be moved to the field devices. The Rosemount 848L uses FOUNDATION fieldbus technology developed and supported by Emerson Process Management and the other members of the independent Fieldbus Foundation.
