ESD and EMI
Electrostatic Discharge (ESD) is the discharge of static electricity. Electromagnetic Interference
(EMI) is a disturbance generated by an external source that affects an electrical circuit by
electromagnetic induction, electrostatic coupling, or conduction. ESD and EMI issues may come up
when installing and connecting the system to the other components. There are many ways to
avoid problems with these issues.
Any operational system with cables for I/O signals, connectivity, or peripheral devices provide an
entry point for ESD and EMI. If Emerson has not manufactured the complete system, including the
enclosure and cables, then it is the responsibility of the system integrator and end-user to protect
their system against potential problems. Filtering, optical isolation, ESD gaskets, and other
measures might be required at the physical point of entry (enclosure).
Products manufactured by Emerson should normally be suitable for use in properly designed and
produced customer equipment (cabinets, racks) without any major redesign. However, the
systems might be subject to ESD and EMI problems once installed and interconnected with other
systems. The end-user, system integrator, or installer must test for possible problems and in some
cases, show compliance to local regulations as required in his country or by the intended
application.
CAUTION
Static-sensitive Devices: Handle only at static-safe work stations.
CAUTION
This is an FCC Class A product intended for use in an industrial environment. In a home or
residential environment, this product may cause radio interference, in which case the user
may be required to take adequate measures.
CAUTION
Drain static electricity before you install or remove any parts. Installing or removing modules
without observing this precaution could result in damage to this and/or other modules or
components in your system.
Wear a properly-functioning anti-static strap and make sure you are fully grounded. Any surface
upon which you place the unprotected module or unit should be static-safe, which is usually
facilitated by the use of anti-static mats. From the time it is removed from the anti-static bag until
it is in the board carrier and functioning properly, extreme care should be taken to avoid zapping
the component with ESD. Be aware that you could zap the component without knowing it; a small
discharge, imperceptible to the eye and touch, can often be enough to damage electronic
components. Extra caution should be taken in cold and dry weather when electrostatics easily
builds up.
Only after ensuring that both you and the surrounding area are protected from ESD, carefully
remove the component from the shipping carton by grasping the module on its edges. Place the
component, in its anti-static bag, flat down on a suitable surface. You may then remove the
component from the anti-static bag by tearing the ESD warning labels.
