Protective conductor (grounding) terminal
Failure to follow these installation guidelines could result in death or serious injury.
Installation and servicing instructions are for use by qualified personnel only. Do not
perform any servicing other than that contained in the operating instructions, unless
qualified.
Verify the installation is done safely and is consistent with the operating environment.
If installed in explosive atmospheres [hazardous areas, classified areas, or an “Ex”
environment], it must be assured that the device certification and installation
techniques are suitable for that particular environment.
Explosion hazard. Do not disconnect equipment when a flammable or combustible
atmosphere is present.
To prevent ignition of flammable or combustible atmospheres, disconnect power
before servicing circuits.
Do not connect a Rosemount 8732EM Transmitter to a non-Rosemount sensor that is
located in an explosive atmosphere.
Substitution of components may impair Intrinsic Safety.
Follow national, local, and plant standards to properly earth ground the transmitter
and sensor. The earth ground must be separate from the process reference ground.
Rosemount Magnetic Flowmeters ordered with non-standard paint options or
non-metallic labels may be subject to electrostatic discharge. To avoid electrostatic
charge build-up, do not rub the flowmeter with a dry cloth or clean with solvents.
NOTICE
The sensor liner is vulnerable to handling damage. Never place anything through the
sensor for the purpose of lifting or gaining leverage. Liner damage may render the sensor
inoperable.
Metallic or spiral-wound gaskets should not be used as they will damage the liner face of
the sensor. If spiral wound or metallic gaskets are required for the application, lining
protectors must be used. If frequent removal is anticipated, take precautions to protect
the liner ends. Short spool pieces attached to the sensor ends are often used for
protection.
Correct flange bolt tightening is crucial for proper sensor operation and life. All bolts must
be tightened in the proper sequence to the specified torque specifications. Failure to
observe these instructions could result in severe damage to the sensor lining and possible
sensor replacement.
In cases where high voltage/high current are present near the meter installation, ensure
that proper protection methods are followed to prevent stray voltage / current from
passing through the meter. Failure to adequately protect the meter could result in damage
to the transmitter and lead to meter failure.
Completely remove all electrical connections from both sensor and transmitter prior to
welding on the pipe. For maximum protection of the sensor, consider removing it from the
pipeline.
