1 About this guide
This guide provides basic guidelines for Rosemount
™
2051G Transmitters. It
does not provide instructions for configuration, diagnostics, maintenance,
service, troubleshooting, Explosion-proof, Flameproof, or intrinsically safe
(I.S.) installations. See the Rosemount 2051G Reference Manual for more
information.
WARNING
Explosions could result in death or serious injury.
Installation of these transmitters 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.
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 could result in death or serious injury.
To avoid process leaks, only use the O-ring designed to seal with the
corresponding flange adapter.
Electrical shock could cause death or serious injury.
Avoid contact with the leads and 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
½–14 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.
