graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

Security messages
Note
Siemens offers IT security mechanisms for its automation and drive product portfolio in order
to support the safe operation of the plant/machine. Our products are also continuously
developed further with regard to IT security. We
therefore recommend that you regularly
check for updates of our products and that you only use the latest versions. You will find
information in:
(
http://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo2&aktprim=99&lang=
en
)
Here, you can register for a product
-specific newsletter.
For the safe operation of a plant/machine, however, it is also necessary to integrate the
automation compo
nents into an overall IT security concept for the entire plant/machine,
which corresponds to the state
-of-the-art IT technology. You will find information on this in:
(http://www.siemens.com/industrialsecurity)
Products from other manufacturers that are being used must also be taken into account.

If information applies to all devices, the term "IE Switches X-300" is used. If information
applies to only a particular product group, the relevant names will be used without extra
information on the type or number of interfaces. Examples: "X-300" stands for non-modular
devices with a compact housing, "XR-300" means all rack devices, "X-300M" means all
modular devices etc.

•Use only approved components, for example supporting brackets, SFPs, 19 inch racks.
•Create any supports you require according the dimension drawing.
Safety notices on use in hazardous areas
General safety notices relating to protection against explosion
WARNING
EXPLOSION HAZARD
DO NOT OPEN WHEN ENERGIZED.
Safety notices when using the device according to Hazardous Locations (HazLoc)
If you use the device under HazLoc conditions you must also keep to the following safety
notices in addition to the general safety notices for protection against explosion:

Important notes on using the SCALANCE X-300 product family
Safety notices on the use of the device
The following safety notices must be adhered to when setting up and operating the device
and during all associated work such as installation, connecting up, replacing or opening the
device.
General information
WARNING
Safety extra low voltage
The equipment is designed for operation with Safety Extra-Low Voltage (SELV) by a
Limited Power Source (LPS). (This does not apply to 100 V...240 V devices.)
This means that only SELV / LPS (Limited Power Source) complying with IEC 60950-1 / EN
60950-1 / VDE 0805-1 must be connected to the power supply terminals. The power supply
unit for the equipment power supply must comply with NEC Class 2, as described by the
National Electrical Code (r) (ANSI / NFPA 70).
If the equipment is connected to a redundant power supply (two separate power supplies),
both must meet these requirements.
A power source that supplies safety extra low voltage combined with a following NEC Class
2 power limiter also meets the requirements according to IEC 60950-1 / EN 60950-1 / VDE
0805-1 or NEC Class 2. A suitable power limiter is for example the redundancy module
SITOP PSE202U NEC Class 2 (article number 6EP1962-2BA00).
WARNING
Opening the device
DO NOT OPEN WHEN ENERGIZED.
General notices about use in hazardous areas
WARNING
Risk of explosion when connecting or disconnecting the device
EXPLOSION HAZARD
DO NOT CONNECT OR DISCONNECT EQUIPMENT WHEN A FLAMMABLE OR
COMBUSTIBLE ATMOSPHERE IS PRESENT.

WARNING
Replacing components
EXPLOSION HAZARD
SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR CLASS I, DIVISION
2 OR ZONE 2.
WARNING
Requirements for the cabinet/enclosure
When used in hazardous environments corresponding to Class I, Division 2 or Class I,
Zone 2, the device must be installed in a cabinet or a suitable enclosure.
Safety notices on use in hazardous areas according to ATEX and IECEx
WARNING
Requirements for the cabinet/enclosure
To comply with EC Directive 94/9 (ATEX95) or the conditions of IECEx, this enclosure must
meet the requirements of at least IP54 in compliance with EN 60529.
WARNING
Suitable cables for temperatures in excess of 70 °C
If the cable or conduit entry point exceeds 70 °C or the branching point of conductors
exceeds 80 °C, special precautions must be taken. If the equipment is operated in an air
ambient in excess of 50 °C - 70 °C, only use cables with admitted maximum operating
temperature of at least 80 °C.
WARNING
Protection against transient voltage surges
Provisions shall be made to prevent the rated voltage from being exceeded by transient
voltage surges of more than 40%. This criterion is fulfilled, if supplies are derived from
SELV (Safety Extra-Low Voltage) only.
