Quick Start Guide
NOTICE
This installation 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 PROFIBUS PA 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 PROFIBUS PA 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. Only
use plugs, adapters, glands, or conduit with a compatible thread form when closing these entries.
