WARNING
Explosions
Explosions could result in death or serious injury.
In an explosion-proof/flameproof installation, do not remove the transmitter covers when power is applied to the unit.
Installation of device in an explosive environment must be in accordance with appropriate local, national, and international
standards, codes, and practices. Review the Product Certifications section of the Rosemount 3051
restrictions associated with a safe installation.
Before connecting a handheld communicator in an explosive atmosphere, ensure the instruments are installed in accordance
with intrinsically safe or non-incendive field wiring practices.
Process leaks
Process leaks may cause harm or result in death.
Install and tighten process connectors before applying pressure.
Do not attempt to loosen or remove flange bolts while the transmitter is in service.
Electrical shock
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.
Replacement equipment
Replacement equipment or spare parts not approved by Emerson for use as spare parts could reduce the pressure retaining
capabilities of the transmitter and may render the instrument dangerous.
Use only bolts supplied or sold by Emerson as spare parts.
Improper assembly
Improper assembly of manifolds to traditional flange can damage sensor module.
For safe assembly of manifold to traditional flange, bolts must break back plane of flange web (i.e., bolt hole) but must not
contact sensor module housing.
Severe changes in the electrical loop may inhibit HART Communication or the ability to reach alarm values. Therefore,
Rosemount absolutely cannot warrant or guarantee that the correct Failure alarm level (High or Low) can be read by the host
system at the time of annunciation.
Physical access
Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end users' equipment. This could
be intentional or unintentional and needs to be protected against.
Physical security is an important part of any security program and fundamental to protecting your system. Restrict physical access
by unauthorized personnel to protect end users' assets. This is true for all systems used within the facility.
