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 housing covers 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.
Both housing covers must be fully engaged to meet flameproof/explosion-proof requirements.

Verify the operating atmosphere of the transmitter is consistent with the appropriate hazardous

location certifications.
Electrical shock could cause death or serious injury.
If the Rosemount ERS System is installed in a high-voltage environment and a fault or installation

error occurs, high voltage may be present on the sensor 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 Rosemount ERS System 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 the device.
For the safe assembly of the manifold to the sensor flange, bolts must break the back plane of the

flange web (i.e. bolt hole) but must not contact the sensor module.
Static electricity can damage sensitive components.
Observe safe handling precautions for static-sensitive components.
