Warning
Risks involved in the use of so-called SIMATIC-compatible modules of non-Siemens
manufacture
"The manufacturer of a product (SIMATIC in this case) is under the general obligation to give
warning of possible risks attached to his product. This obligation has been extended in recent
court rulings to include parts supplied by other vendors. Accordingly, the manufacturer is obliged
to observe and recognize such hazards as may arise when a product is combined with products
of other manufacture.
For this reason, we feel obliged to warn our customers who use SIMATIC products not to
install so-called SIMATIC-compatible modules of other manufacture in the form of
replacement or add-on modules in SIMATIC systems.
Our products undergo a strict quality assurance procedure. We have no knowledge as to
whether outside manufacturers of so-called SIMATIC-compatible modules have any quality
assurance at all or one that is nearly equivalent to ours. These so-called SIMATIC-compatible
modules are not marketed in agreement with Siemens; we have never recommended the use of
so-called SIMATIC-compatible modules of other manufacture. The advertising of these other
manufacturers of so-called SIMATIC-compatible modules wrongly creates the impression that
the subject advertised in periodicals, catalogs or at exhibitions had been agreed with us. Where
so-called SIMATIC-compatible modules of non-Siemens manufacture are combined with our
SIMATIC automation systems, we have a case of our product being used contrary to recommen-
dations. Because of the variety of applications of our SIMATIC automation systems and the large
number of these products marketed worldwide, we cannot give a concrete description specifi-
cally analyzing the hazards created by these so-called SIMATIC-compatible modules. It is be-
yond the manufacturer’s capabilities to have all these so-called SIMATIC-compatible modules
checked for their effect on our SIMATIC products. If the use of so-called SIMATIC-compatible
modules leads to defects in a SIMATIC automation system, no warranty for such systems will be
given by Siemens.
In the event of product liability damages due to the use of so-called SIMATIC-compatible mo-
dules, Siemens are not liable since we took timely action in warning users of the potential ha-
zards involved in so-called SIMATIC-compatible modules."

Guidelines for Handling
Electrostatically Sensitive Devices (ESD)
1 What is ESD?
VSLI chips (MOS technology) are used in practically all SIMATIC and TELEPERM modules.
These VLSI components are, by their nature, very sensitive to overvoltage and thus to
electrostatic discharge:
They are therefore defined as
Electrostatically Sensitive Devices: "ESD"
"ESD" is the abbreviation used internationally.
The following warning label on the cabinets, subracks and packing indicates that electrostatically
sensitive components have been used and that the modules concerned are susceptible to touch:
ESDs can be destroyed by voltage and energy levels which are far below the level perceptible
to human beings. Such voltages already occur when a component or a module is touched by a
person who has not been electrostatically discharged. Components which have been subjected
to such overvoltages cannot, in most cases, be immediately detected as faulty; the fault occurs
only after a long period in operation.
An electrostatic discharge
– of 3500 V can be felt
– of 4500 V can be heard
– must take place at a minimum of 5000 V to be seen.
But just a fraction of this voltage can already damage or destroy an electric component.
The typical data of a component can suffer due to damage, overstressing or weakening caused
by electrostatic discharge; this can result in temporary fault behavior, e.g. in the case of
– temperature variations,
– mechanical shodks,
– vibrations,
– change of load.
Only the consequent use of protective equipment and careful observation of the precautions for
handling such components can effectively prevent functional disturbances and failures of ESD
modules.

2 When is a Static Charge Formed?
One can never be sure that the human body or the material and tools which one is using are not
electrostatically charged.
Small charges up to 100 V are very common; these can, however, very quickly rise up to
35 000 V!
Examples of static charge:
– Walking on a carpet up to 35 000 V
– Walking on a PVC flooring up to 12 000 V
– Sitting on a cushioned chair up to 18 000 V
– Plastic desoldering unit up to 8 000 V
– Books, etc. with a plastic binding up to 8 000 V
– Plastic bag up to 5 000 V
– Plastic coffee cup up to 5 000 V
3 Important Protective Measures against Static Discharge
•Most plastic materials are highly susceptible to static charge and must therefore be kept as
far away as possible from ESDs!
•Personnel who handle ESDs, the work table and the packing must all be carefully grounded!
4 Handling of ESD Modules
•One basic rule to be observed is that electronic modules should be touched by hand
only if this is necessary for any work to be done on them. Do not touch the component
pins or the conductors.
•Touch components only if
– the person is grounded at all times by means of a wrist strap
or
– the person is wearing special anti-static shoes or shoes with a grounding strip.
•Before touching an electronic module, the person concerned must ensure that (s)he is
not carrying any static charge. The simplest way is to touch a conductive, grounded
item of equipment (e.g. a blank metallic cabinet part, water pipe, etc.) before touching
the module.
•Modules should not be brought into contact with insulating materials or materials which
take up a static charge, e.g. plastic foil, insulating table tops, synthetic clothing, etc..
•Modules should only be placed on conductive surfaces (table with anti-static table top,
conductive foam material, anti-static plastic bag, anti-static transport container).
•Modules should not be placed in the vicinity of visual display units, monitors or TV sets
(minimum distance from screen > 10 cm).
The diagram on the next page shows the required protective measures against electrostatic
discharge.

5 Measurements and Modifications to ESD Modules
•Measurements on modules may only be carried out under the following conditions:
– the measuring equipment is grounded (e.g. via the PE conductor of the power supply
system) or
– when electrically isolated measuring equipment is used, the probe must be discharged
(e.g. by touching the metallic casing of the equipment) before beginning measurements.
•Only grounded soldering irons may be used.
6 Shipping of ESD Modules
Anti-static packing material must always be used for modules and components, e.g. metalized
plastic boxes, metal boxes, etc. for storing and dispatch of modules and components.
If the container itself is not conductive, the modules must be wrapped in a conductive material
such as conductive foam, anti-static plastic bag, aluminum foil or paper. Normal plastic bags or
foils should not be used under any circumstances.
For modules with built-in batteries ensure that the conductive packing does not touch or
short-circuit the battery connections; if necessary cover the connections with insulating tape or
material.
