Rosemount 3051S ERS System

CONSIDERATIONS

General
2-2
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 that the operating atmosphere of the transmitter is consistent with the appropriate
hazardous location certifications.
Electrical shock could cause death or serious injury. If the 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 ERS system is in service.
• Replacement equipment or spare parts not approved by Emerson Process Management
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 Process Management 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.
Measurement performance depends upon proper installation of each sensor
and impulse piping. Mount each 3051S ERS sensor close to the process and
use minimum piping to achieve best performance. Also, consider the need for
easy access, personnel safety, practical field calibration, and a suitable
environment. Install each sensor to minimize vibration, shock, and
temperature fluctuation.
NOTE:
Install the enclosed pipe plugs (found in the box) in any unused conduit
openings. For proper straight and tapered thread engagement requirements,
see the appropriate approval drawings in Appendix C: Product Certifications.
