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 re-
placement or add–on modules in SIMATIC systems.
Our products undergo a strict quality assurance procedure. We have no knowledge as to wheth-
er outside manufacturers of so–called SIMATIC–compatible modules have any quality assur-
ance at all or one that is nearly equivalent to ours. These so–called
SIMATIC–compatible mod-
ules 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 man-
ufacturers for so–called SIMATIC– compatible modules wrongly creates the impression that the
subject advertised in periodicals, catalogues or at exhibitions had been agreed to by 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 specifical-
ly analyzing the hazards created by these so–called SIMATIC– compatible modules. It is beyond
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 mod-
ules, Siemens is not liable since we have taken timely action in warning users of the potential
hazards involved in so–called
SIMATIC– compatible modules.”

PROTECTION
IN ACTION
Information Concerning
Packaging Material/Notes on Disposal
Dear Customer !
Our high–quality products cannot reach you safely without effective protective packaging. The
size of the packaging is kept to an absolute minimum.
All our packaging materials are harmless to the environment and can be disposed of without dan-
ger.
Wood is not chemically treated.
Cardboard is made primarily of waste paper which can then be torn up and given to a waste paper
collection.
Sheeting is made of polyethylene (PE), tapes of polypropylene (PP) and CFC–free padding of foa-
med polystyrene (PS).
These materials are pure hydrocarbons and can be recycled. Please dispose of these valuable
secondary raw materials at a recycling center.
Recycling saves raw materials and cuts down on the amount of trash.
Ask your city administration for the address of the recycling center nearest you to dispose of
pak-
king materials and discarded devices.
Thank you for your help !
