Introduction
Make sure the transmitter is installed by qualified personnel and in accordance with
applicable code of practice.
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 services other than those contained in this manual unless you are
qualified.
Any substitution of non-authorized parts or repair, other than exchanging the
complete transmitter head or antenna 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ratings and certifications are no longer valid on any products that have been damaged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.
Verify that the operating environment of the transmitter is consistent with the
appropriate hazardous locations specifications. See
page 217 in this manual.
To prevent ignition of flammable or combustible atmospheres, disconnect power
before servicing.
In an Explosion-proof/Flameproof installation, do not remove the transmitter cover
when power is applied to the unit.
Before connecting a HART
in an explosive atmosphere, make sure the instruments in the loop are installed in
accordance with intrinsically safe or non-incendive field wiring practices.
To avoid process leaks, only use O-rings designed to seal with the corresponding
flange adapter.
Avoid contact with the leads and terminals. High voltage that may be present on leads
can cause electrical shock.
Make sure the main power to the Rosemount 5400 Series transmitter is off and the
lines to any other external power source are disconnected or not powered while wiring
the transmitter.
Antennas with non-conducting surfaces (e.g. Rod antenna and Process Seal antenna)
may generate an ignition-capable level of electrostatic charge under extreme
conditions.
Therefore, when the antenna is used in a potentially explosive atmosphere,
appropriate measures must be taken to prevent electrostatic discharge.
