SAFETY MESSAGES Instructions and procedures in this section may require special precautions to
ensure the safety of the personnel performing the operations. Please read the
following safety messages before performing any operation described in this
section.
Warnings
Explosions could result in death or serious injury:
• Verify that the operating atmosphere of the sensor
and transmitter is consistent with the appropriate
hazardous locations certifications.
• Do not remove the transmitter cover in explosive atmospheres
when the circuit is alive.
• 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.
• Both transmitter covers must be fully engaged to meet
explosion-proof requirements.
Failure to follow safe installation and servicing guidelines could result in death or
serious injury:
• Make sure only qualified personnel perform the installation.
• Do not perform any service other than those contained in this manual unless
qualified.
Process leaks could result in death or serious injury:
• The electrode compartment may contain line pressure; it must be depressurized
before the cover is removed.
High voltage that may be present on leads could cause
electrical shock:
• Avoid contact with leads and terminals.
