Legal informationWarning notice systemThis manual contains notices you have to observe in order to ensure your personal safety, as well as to preventdamage to property. The notices referring to your personal safety are highlighted in the manual by a safety alertsymbol, notices referring only to property damage have no safety alert symbol. These notices shown below aregraded according to the degree of danger.DANGERindicates that death or severe personal injury will result if proper precautions are not taken.WARNINGindicates that death or severe personal injury may result if proper precautions are not taken.CAUTIONwith a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.CAUTIONwithout a safety alert symbol, indicates that property damage can result if proper precautions are not taken.NOTICEindicates that an unintended result or situation can occur if the corresponding information is not taken intoaccount.If more than one degree of danger is present, the warning notice representing the highest degree of danger willbe used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating toproperty damage.Qualified PersonnelThe device/system may only be set up and used in conjunction with this documentation. Commissioning andoperation of a device/system may only be performed by qualified personnel. Within the context of the safety notesin this documentation qualified persons are defined as persons who are authorized to commission, ground andlabel devices, systems and circuits in accordance with established safety practices and standards.Proper use of Siemens productsNote the following:WARNINGSiemens products may only be used for the applications described in the catalog and in the relevant technicaldocumentation.
