Service and Troubleshooting
Failure to follow safe installation and service guidelines could result in death or
serious injury.
Make sure only qualified personnel perform installation or service.
Use the equipment only as specified in this manual. Failure to do so may impair the
protection provided by the equipment.
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ratings and certifications are no longer valid on any products that have been damaged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.
Explosions could result in death or serious injury.
Verify that the operating environment of the transmitter is consistent with the
appropriate hazardous locations specifications.
In an Explosion-proof/Flameproof installation, do not remove the transmitter cover
when power is applied to the unit.
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.
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.
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.
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.
