5.2 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 (
). Refer to the following safety messages before performing an operation preceded
by this symbol.
Explosions could result in death or serious injury.
Installation of this transmitter in an explosive environment must be in accordance with the
appropriate local, national, and international standards, codes, and practices. Review the approvals
section of the reference manual for any restrictions associated with a safe installation.

Before connecting a Field Communicator in an explosive atmosphere, ensure the instruments in
the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices.

In an Explosion-Proof/Flameproof installation, do not remove the transmitter covers when power
is applied to the unit.
Process leaks may cause harm or result in death.
Install and tighten process connectors before applying pressure.
Electrical shock can result in death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads can cause
electrical shock.
