Warnings
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.
