CAUTION
Heavy Weight
The heavy weight of the SIPLACE JTF-MW (~ 60 kg/~132 lb) could cause injuries if the module
is not handled correctly.
► Do not lift or carry the module alone.
► Use lifting aids and proper lifting techniques when removing or replacing.
► You might need to enlist the help of a second person.
Almost all of the modules in use today are equipped with highly integrated MOS blocks and compo-
nents. The manufacturing techniques used mean that these electronic components are extremely sen-
sitive to overvoltage and thus to electrostatic discharge.
The abbreviation for such modules is 'ESD' (Electrostatic Sensitive Device). This is
used internationally, although the German abbreviation 'EGB' may also be seen. The
following symbol on cabinet rating plates, racks or packaging indicates that compo-
nents 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 perceived
by humans. Such voltages occur if a person touches a component or module without earthing them-
selves. Components that are exposed to such overvoltages do not generally appear to be defective im-
mediately - incorrect behavior starts after the component or module has been in operation for some
time.

Important Measures to Protect Against Static Charging
► Most plastics can easily become charged and must therefore be kept away from at-risk components.
► Always ensure that people, the workplace and packaging are safely earthed when handling electro-
static sensitive components.

2.3.3 Handling ESD Modules
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 conductive
and earthed object immediately before you touch the module (such as unpainted parts of a switch cab-
inet, 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 bring modules near visual display units, monitors or televisions. Keep them at least 10 cm away
from the screen.

2.3.4 Measurements and Modifications to ESD Modules
Measurements and Modifications to ESD Modules
Measurements of the assemblies may only be taken if
▪ The measuring device has been grounded (e.g. via protective conductor) or
▪ The measuring head of the potential-free measuring device has been briefly discharged before
measurement (e.g. touching blank metal control unit housing).
► Always use an earthed soldering iron if you carry out any soldering work.
2.3.5
2.3.5 Dispatching ESD Modules
Dispatching ESD Modules
► Always store modules and components in conductive packaging (e.g. metallized plastic bags or met-
al sleeves) and dispatch them in conductive packaging.
► If the packaging is not conductive, place the modules in a conductive envelope before packaging.
Use conductive foam 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 mate-
rial.
