Quick Start Guide
NOTICE
This guide provides basic guidelines for Rosemount 2051 Transmitters. It does not provide instructions for
configuration, diagnostics, maintenance, service, troubleshooting, Explosion-Proof, Flame-Proof, or
intrinsically safe (I.S.) installations. Refer to the Rosemount 2051 Reference Manual for more instruction.
This manual is also available electronically on EmersonProcess.com/Rosemount.
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. Review the approvals section of the Rosemount
2051 Reference Manual for any restrictions associated with a safe installation.
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. Entries
marked “M20” are M20 ⫻1.5 thread form. On devices with multiple conduit entries, all entries will have
the same thread form. Only use plugs, adapters, glands, or conduit with a compatible thread form when
closing these entries.
When installing in a hazardous location, use only appropriately listed or Ex certified plugs, adapters, or
glands in cable/conduit entries.
