1.3.4 ESD guidelines
1.3.4.1 What does ESD mean?
Fig.1: ESD label
Almost all of the modules in use today are equipped with highly integ-
rated Metal-Oxide-Semiconductor (MOS) blocks and components.
The manufacturing techniques used mean that these electronic com-
ponents are extremely sensitive to overvoltage and thus to electro-
static discharge.
The abbreviation for such modules is "ESD" (Electrostatic Sensitive
Device). "ESD" is used internationally. The following symbol on cab-
inet rating plates, racks or packaging indicates that components
which are sensitive to electrostatic discharge have been used and
thus that the modules concerned are also touch-sensitive.
ESDs can be destroyed by voltages and power levels that are far below the level that can be per-
ceived by humans. Such voltages occur if a person touches a component or module without
earthing themselves. Components that are exposed to such overvoltages do not generally appear
to be defective immediately - incorrect behavior starts after the component or module has been in
operation for some time.
1.3.4.2 Important measures to protect against static charging
► Most plastics can easily become charged and must therefore be kept away from at-risk com-
ponents.
► Always ensure that people, the workplace and packaging are safely earthed when handling
electrostatic sensitive components.
1.3.4.3 Handling ESD modules
Do not touch electronic modules unless it is absolutely essential to do so in order to carry out other
work. If it is necessary, make sure that you do not touch the pins or printed conductors when you
pick up flat modules.
Do not touch components unless:
●
you are constantly earthed by an ESD wrist strap or
●
You are wearing ESD shoes or ESD shoe earthing strips on an ESD floor.
Always discharge yourself before you touch an electronic module. To do this, simply touch a con-
ductive and earthed object immediately before you touch the module (such as unpainted parts of a
switch cabinet, a water pipe, etc.).
Do not allow modules with chargeable and highly insulating materials to touch one another, e.g.
plastic films, insulating table surfaces or items of clothing made from synthetic fibers.
Always place the modules on a conductive surface (table with an ESD coating, conductive ESD
foam, ESD bag or container).
Do not move the assemblies near to data view devices, monitors or television units. Keep a min-
imum distance of 10 cm to monitors.
1.3.4.4 Measurements and modifications to ESD modules
Do not take measurements on the modules unless the following conditions are fulfilled:
●
The measuring device is earthed (e.g. via PE conductors) or
●
You discharge the measuring head just before taking measurements with a potential-free
measuring device (e.g. by touching an unpainted metal part of the controller casing).
► Always use an earthed soldering iron if you carry out any soldering work.

1.3.4.5 Dispatching ESD modules
► Always store modules and components in conductive packaging (e.g. metallized plastic bags
or metal sleeves) and dispatch them in conductive packaging.
► If the packaging is not conductive, place the modules in a conductive envelope before pack-
aging. Use conductive expanded rubber, ESD bags, domestic aluminum foil or paper, for
example. NEVER use plastic bags or film.
► If the module has integral batteries, ensure that the conductive packaging does not touch or
short circuit the battery terminals and, if necessary, first cover the terminals with insulating
tape or material.
1.3.5 Validity of document
This document applies to modules of the type SIPLACE wafer system.
The work described in this manual is divided into modules and is largely identical for all modules:
●
If the work required should differ from the standard procedure, this will be indicated with refer-
ence to the delivery state.
●
Diagrams should be seen as examples e.g. a different paint finish does not mean that the fol-
lowing information only applies to the modules shown.
Please read the circuit diagram folder for any electrical checks.
