IMPORTANT NOTICE
This installation guide provides basic guidelines for Rosemount
2051 transmitters. It does not provide instructions for configuration, diagnostics,
maintenance, service, troubleshooting, Explosion-proof, Flameproof, or intrinsically safe
(I.S.) installations. Refer to the 2051 reference manual (document number
00809-0100-4101) for more instruction. This manual is also available electronically on
www.emersonprocess.com/rosemount.
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 2051 reference manual for any restrictions associated
with a safe installation.
• 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.
• 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.
• To avoid process leaks, only use the o-ring designed to seal with the corresponding
flange adapter.
Electrical shock can result in death or serious injury.
• Avoid contact with the leads and the terminals. High voltage that may be present on
leads can cause electrical shock.
Conduit/Cable Entries
• Unless marked, the conduit/cable entries in the transmitter housing use a
1
/2-14 NPT
thread form. Only use plugs, adapters, glands or conduit with a compatible thread
form when closing these entries.
