SAFETY MESSAGES

Procedures and instructions in this section may require special precautions to 
ensure the safety of the personnel performing the operations. Information that 
raises potential safety issues is indicated by a warning symbol (

). Please 

refer to the following safety messages before performing an operation 
preceded by this symbol.

.

Explosions could result in death or serious injury.

Verify that the operating environment of the transmitter is consistent with the appropriate 
approval certifications.

Before connecting a HART-based communicator in an explosive atmosphere, make 
sure the instruments in the loop are installed in accordance with intrinsically safe or 
non-incendive field wiring practices.

Do not remove the housing cover in explosive atmospheres when the circuit is alive.

Failure to follow safe installation and servicing guidelines could result in death or 
serious injury.

Make sure only qualified personnel perform the installation.

Use the equipment only as specified in this manual. Failure to do so may impair the 
protection provided by the equipment.

Do not perform any service other than those contained in this manual unless you are 
qualified.

High voltage that may be present on leads could cause electrical shock.

Avoid contact with leads and terminals. 

Make sure the main power to the Rosemount 3100 Series transmitter is off, and the lines 
to any other external power source are disconnected or not powered while wiring
the transmitter.
