Explosions could result in death or serious injury.
Do not remove the transmitter cover in explosive atmospheres when the circuit is live.
Verify the operating atmosphere of the transmitter is consistent with the appropriate hazardous
locations certifications.
Before connecting a communicator in an explosive atmosphere, make sure the instruments in the
segment 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.
Failure to follow these installation guidelines could result in death or serious injury.
Make sure only qualified personnel perform the installation.
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 the transmitter leads and terminals.
Use extreme caution when making contact with the leads and terminals.
Process leaks could result in death or serious injury.
Install and tighten all four flange bolts before applying pressure.
Do not attempt to loosen or remove flange bolts while the transmitter is in service.
Replacement equipment or spare parts not approved by Emerson for use as spare parts could
reduce the pressure retaining capabilities of the transmitter and may render the instrument
dangerous.
Use only bolts supplied or sold by Emerson as spare parts.
Improper assembly of manifolds to traditional flange can damage sensor module.
For safe assembly of manifold to traditional flange, bolts must break back plane of flange web (i.e.,
bolt hole) but must not contact module housing.
Sensor module and electronics housing must have equivalent approval labeling in order to
maintain hazardous location approvals.
When upgrading, verify sensor module and electronics housing certifications are equivalent.
Differences in temperature class ratings may exist, in which case the complete assembly takes the
lowest of the individual component temperature classes (for example, a T4/T5 rated electronics
housing assembled to a T4 rated sensor module is a T4 rated transmitter.)
