WARNING
Explosions could result in death or serious injury.
Installation of device in an explosive environment must be in accordance with appropriate local,
national, and international standards, codes, and practices. Review the approvals section of the
Rosemount 3051 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.
WARNING
Process leaks
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
Electrical shock can result in 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 otherwise marked, the conduit/cable entries in the housing enclosure use a
½
–14 NPT
form. Only use plugs, adapters, glands, or conduit with a compatible thread form when closing
these entries.
Entries marked
M20
are M20 x 1.5 thread form. On devices with multiple conduit entries, all
entries will have the same thread form.
