2.3 System readiness
Confirm HART revision capability

If using HART based control or asset management systems, confirm the HART
capability of those systems prior to transmitter installation. Not all systems are capable
of communicating with HART Revision 7 protocol. This transmitter can be configured
for either HART Revision 5 or 7.

For instructions on how to change the HART revision of your transmitter, see “System
readiness” on page 8 .
2.3.1 Confirm correct device driver

Verify the latest Device Driver files are loaded on your systems to ensure proper
communications.

Download the latest Device Driver at www.emersonprocess.com or
www.hartcomm.org
Failure to follow these installation guidelines could result in death or serious injury.

Make sure only qualified personnel perform the installation.
Explosions could result in death or serious injury.

Do not remove the connection head cover in explosive atmospheres when the
circuit is live.

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.

Verify the operating atmosphere of the transmitter is consistent with the appropriate
hazardous locations certifications.

All connection head covers must be fully engaged to meet explosion-proof
requirements.
Process leaks could result in death or serious injury.

Do not remove the thermowell while in operation.

Install and tighten thermowells and sensors before applying pressure.
Electrical shock could cause death or serious injury.

Use extreme caution when making contact with the leads and terminals.
