Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
indicates that death or severe personal injury will result if proper precautions are not taken.
indicates that death or severe personal injury may result if proper precautions are not taken.
indicates that minor personal injury can result if proper precautions are not taken.
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.
The product/system described in this documentation may be operated only by
for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

Notices on use in hazardous areas according to ATEX and IECEx
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.
The fiber-optic bus connections labeled SCALANCE MM900 (see type plate) may also be
led through a hazardous area zone1 (see also Approvals (Page 47), section "Explosion
Protection Directive (ATEX)").
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.
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.
Important notes on using the device in hazardous areas
WARNING - EXPLOSION HAZARD -
DO NOT DISCONNECT WHILE CIRCUIT IS LIVE UNLESS AREA IS KNOWN TO BE
NON-HAZARDOUS.
Restricted area of application
This equipment is suitable for use in Class I, Division 2, Groups A, B, C and D or nonhazardous locations only.
