Instructions and procedures in this section may require special precautions to ensure the safety of the personnel performing the operations. Information that raises potential safety issues is indicated by a warning symbol (SAFETY MESSAGES). Please refer to the following safety messages before performing an operation preceded by this symbol.

Explosions could result in death or serious injury.

Do not remove the enclosure cover in explosive atmospheres when the circuit is live.

Verify that the operating atmosphere of the transmitter is consistent with the appropriate hazardous locations certification.

Enclosure covers must be fully engaged to meet explosion-proof requirements.

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. Doing so 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 condition or installation error occurs, high voltage may be present on transmitter leads and terminals.

Use extreme caution when making contact with leads and terminals.
