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 1151 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/Flame-Proof installation, do not remove the transmitter covers when power 

is applied to the unit. 

• To avoid process leaks, only use the o-ring designed to seal with the corresponding flange 

adapter. 

• Avoid contact with the leads and the terminals. High voltage that may be present on leads can 

cause electrical shock.

This installation guide provides basic guidelines for Rosemount 1151 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 1151 reference manual 
(document number 00809-0100-4360) for more instruction. This manual is also available electronically 
on www.emersonprocess.com/rosemount.
