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 show up incomplete and operational systems. There are many ways to avoid
problems with these issues.
Any operational system with cables for I/O signals, connectivity, or peripheral devices
provides an entry point for ESD and EMI. If Emerson does not manufacture the complete
system, including enclosure and cables, 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 wall
of box or rack). For example, it is state-of-the-art that protection cannot be done at the
internal connector of an RTM if a cable is attached and routed outside the enclosure. It has
to be done at the physical entry point as specified in this document.
Products manufactured by Emerson should normally be suitable for use in properly
designed and produced customer equipment (system boxes or operational systems)
without any major redesign. However, the systems might be subject to problems and issues
once assembled, cabled, and used. 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.
ESD is a major cause of electronic component failure. The component has been packed in a
static-safe bag to protect it from ESD while it is in the bag. Before removing the component
or any other electronic product from its static-safe bag, be prepared to handle it in a static-
safe environment.
CAUTION
Static-sensitive Devices: Handle only at static-safe workstations.
CAUTION
This is an FCC Class A product 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
