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.
Verify that the operating environment of the gauge is consistent with the
appropriate hazardous locations certifications.
Before connecting a Field 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 gauge 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
™
5300 Transmitter is off and the
lines to any other external power source are disconnected or not powered while
wiring the gauge.
Probes covered with plastic and/or with plastic discs may generate an
ignition-capable level of electrostatic charge under certain extreme conditions.
Therefore, when the probe is used in a potentially explosive atmosphere,
appropriate measures must be taken to prevent electrostatic discharge.
Process leaks could result in death or serious injury.
Make sure that the transmitter is handled carefully. If the process seal is damaged,
gas might escape from the tank if the transmitter head is removed from the
probe.
Any substitution of non-authorized parts or repair, other than exchanging the
complete transmitter head or probe assembly, may jeopardize safety and is
prohibited.
Unauthorized changes to the product are strictly prohibited as they may
unintentionally and unpredictably alter performance and jeopardize safety.
Unauthorized changes that interfere with the integrity of the welds or flanges,
such as making additional perforations, compromise product integrity and safety.
Equipment ratings and certifications are no longer valid on any products that have
been damaged or modified without the prior written permission of Emerson
™
Process Management. Any continued use of product that has been damaged or
modified without prior written authorization is at the customer's sole risk and
expense.
