SAFETY MESSAGES 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 ( ). Please
refer to the following safety messages before performing an operation
preceded by this symbol.
Explosions may result in death or serious injury.
• Do not remove the instrument cover in explosive atmospheres when the circuit is
live.
• Before connecting a 375 Field 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.
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 transmitter leads and terminals.
• Use extreme caution when making contact with the leads and terminals.
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.
