WARNING!
Explosion hazards. Failure to follow these instructions could cause an explosion, resulting in
death or serious injury.
• 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.
• Do not remove transmitter covers in explosive atmospheres when the circuit is live.
Both transmitter covers must be fully engaged to meet explosion-proof requirements.
• Do not disconnect equipment when a flammable or combustible atmosphere is present.
• 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.
• Do not connect a Rosemount transmitter to a non-Rosemount sensor that is located in
an explosive atmosphere. The transmitter has not been evaluated for use with other
manufacturers' magnetic flowmeter sensors in hazardous (Ex or Classified) areas.
Special care should be taken by the end-user and installer to ensure the transmitter
meets the safety and performance requirements of the other manufacturer’s
equipment.
• 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.
WARNING!
Electrical hazards. Failure to follow these instructions could cause damaging and unsafe
discharge of electricity, resulting in death or serious injury.
• 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.
• Disconnect power before servicing circuits.
• Allow ten minutes for charge to dissipate prior to removing electronics compartment
cover. The electronics may store energy in this period immediately after power is
removed.
• Avoid contact with leads and terminals. High voltage that may be present on leads could
cause electrical shock.
• 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.
