SAFETY MESSAGES
Instructions and procedures in this section may require special
precautions to ensure the safety of the personnel performing the
operations. Information that potentially raises safety issues is indicated
by a warning symbol ( ). Please refer to the following safety messages
before performing an operation preceded by this symbol.
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 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.
Process leaks could result in death or serious injury:
•
Install and tighten thermowells or sensors before applying pressure, or process
leakage may result.
•
Do not remove the thermowell while in operation. Removing while in operation
may cause process fluid leaks.
Electrical shock could cause death or serious injury. If the sensor is installed in a
high-voltage environment and a fault or installation error occurs, high voltage may
be present on the transmitter leads and terminals:
•
Use extreme caution when making contact with the leads and terminals.
