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,
Flame proof, or intrinsically safe (I.S.) installations. Refer to the 2051 PROFIBUS PA reference
manual (document number 00809-0300-4101) 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 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.
