Warnings
WARNING
Explosions could result in death or serious injury.
Installation of this transmitter in an explosive environment must be in accordance with the appropriate local, national, and
international standards, codes, and practices. Please review the approvals section of the Rosemount 2051 Reference Manual for
any restrictions associated with a safe installation.
• Before connecting a HART
®
communicator in an explosive atmosphere, ensure the instruments in the loop are installed in
accordance with intrinsically safe or non-incendive field wiring practices.
• In an Explosion-Proof/Flameproof installation, do not remove the transmitter covers when power is applied to the unit.
Process leaks may cause harm or result in death.
• Install and tighten process connectors before applying pressure.
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.
WARNING
Electrical shock can result in death or serious injury.
• Avoid contact with the leads and terminals.
Process leaks could result in death or serious injury.
• Install and tighten all four flange bolts before applying pressure.
• Do not attempt to loosen or remove flange bolts while the transmitter is in service.
Replacement equipment or spare parts not approved by Emerson Process Management 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 Process Management as spare parts.
• Refer to page 208 for a complete list of spare parts.
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.
