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 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 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certifications are no longer valid on any products that have been damaged or modified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.
