Installation
2.2.1 Warnings
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 transmitter cover in explosive atmospheres when the circuit is live.
Before connecting a 375 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 flameproof/explosion-proof
requirements.
Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
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 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 safe assembly of manifold to traditional flange, bolts must break back plane of
flange web (i.e., bolt hole) but must not contact the sensor module.
Improper installation or repair of the SuperModule
assembly with high pressure option
(P0) could result in death or serious injury.
For safe assembly, the high pressure SuperModule assembly must be installed with
ASTM A193 Class 2 Grade B8M Bolts and either a 305 manifold or a DIN-compliant
traditional flange.
Static electricity can damage sensitive components.
Observe safe handling precautions for static-sensitive components.
