Only personnel familiar with these types of products and associated machinery should plan or
implement the installation, start-up, configuration, and subsequent maintenance of the
Bulletin 840E level switch.
1. 3 Operational Safety
• Functional safety
The Bulletin 840E level switches were developed according to the standards EN 60068 and
EN 61326.
• Hazardous areas
The Bulletin 840E is not approved for use in intrinsic safety (hazardous area) applications.
1. 4 Return
Before returning a device to Rockwell Automation, be sure to remove all fluid residue. This is
particularly important if the fluid is a health hazard, e.g. flammable, toxic, caustic, carcinogenic,
etc.
ATTENTION: Installation and commissioning must be
carried out by qualified individuals. Failure to comply may
result in personal injury or equipment damage.
ATTENTION: Do not return a measuring device if you are not
absolutely certain that all traces of hazardous substances have
been removed, e.g. substances which have penetrated crevices
or diffused through plastic.
