3.2 Considerations before installation
Important
Emerson is not in a position to evaluate or guarantee the compatibility of the process fluid
or other process parameters with the product, options, configuration or materials of
construction selected.
3.2.1 Safety considerations
Control drawings for hazardous area installations are in Appendix B: Product Certifications ,
and there are safety instructions in the Rosemount 2140 Product Certifications Manual
(see Emerson.com/Rosemount for other language versions).
3.2.2 Environmental considerations
The Rosemount 2140 Level Detector and Rosemount 2140:SIS Level Detector are wired
point level detectors, and are available as Intrinsically Safe (IS) or explosion-proof/flame-
proof versions for hazardous area installations. There are also ordinary location versions for
unclassified, safe areas. Approvals are listed in
Appendix B: Product Certifications of this
manual.
These level detectors are designed for open or closed tanks, and pipe installation. It is
weatherproof and protected against the ingress of dust, but must be protected from
flooding. Avoid installing the level detector near heat sources.
External surface may be hot.

Care must be taken to avoid possible burns.
Process leaks may cause harm or result in death.

Install and tighten process connectors before applying pressure.

Do not attempt to loosen or remove process connectors while a level detector is in
service.
Electrical shock can result in death or serious injury.

If the level detector is installed in a high voltage environment and a fault condition
or installation error occurs, high voltage may be present on leads and terminals.

Use extreme caution when making contact with the leads and terminals.

Make sure that power to the level detector is off while making connections.
Replacement equipment or spare parts not approved by Emerson for use as spare
parts could reduce the pressure retaining capabilities of the level detector and
may render the instrument dangerous.

Use only spare parts supplied or sold by Emerson.
