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.
• 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.
• Flow meters 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 flow meter 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.
• Flow meters 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 flow meter with a dry cloth or clean with solvents.
NOTICE
Damage hazards
Failure to follow these instructions could result in damage or destruction of equipment.
• 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
