Warnings
Explosions could result in death or serious injury:
• 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.
• Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
• Both transmitter covers must be fully engaged to meet
explosion-proof requirements.
Failure to follow these installation guidelines could result in death or serious injury:
• Make sure only qualified personnel perform the installation.
High voltage that may be present on leads could cause electrical shock:
• Avoid contact with leads and terminals.
Use appropriately rated sanitary clamps and gaskets during installation. The
maximum working pressure of the clamp and gasket must be greater than or equal to
the working pressure range of the transmitter. Failure to use proper clamps and
gaskets can cause process leaks and can result in death or serious injury.
