Protection Against ESD
This section provides guidelines regarding the protection of XDM-300
equipment and its components against electrostatic damage during handling,
packing/unpacking, transport, installation, commissioning, inspections,
servicing, and maintenance.
Electronic equipment, assemblies, and components that are sensitive to
electrostatic discharge (ESD) or include sensitive items are identified by the
basic ESD warning symbol shown in the following figure.
Figure 2-8: Basic ESD warning symbol
The information provided in this section is in line with CENELEC Electronic
Components Committee (CECC) specification CECC 00 015, which deals with
protection of devices sensitive to ESDs.
Most types of electronic equipment, assemblies, and components can be
damaged by electrostatic discharges. An electrostatic discharge between two
objects occurs when an object carrying static electrical charges touches or is
brought near another object.
Static electrical charges appear as a result of friction between surfaces of
insulating materials or separation of two such surfaces, and may also be
induced by electrical fields. Routine activities such as walking across an
insulating floor, friction between garment parts, friction between objects, and
so on, can easily build up charges to levels that may cause damage, especially
when humidity is low.
