Before connecting a 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.
