GB - 41. Safety InstructionsPrior to performing any work on the unit the user must familiarize himself with the unit. This includes especiallythe knowledge and observance of the safety and warning directions. The pictographs used in this instructionmanual have following meaning:Danger Refers to danger of life by electric current.Warning Refers to possible danger of injury or life.Note Refers to tips and additional information.1.1 ValidityThe information contained in the technical documentation, as well as any user-specific advice in spoken andwritten and through tests, are made to best of our knowledge and information about the application. However,they are considered for information only without responsibility. This also applies to any violation of industrialproperty rights of a third-party.Inspection of our units in view of their suitability for the intended use must be done generally by the user.Inspections are particulary necessary, if changes are executed, which serve for the further development oradaption of our products to the applications (hardware, software or download lists). Inspections must be re-peated completely, even if only parts of hardware, software or download lists are modified.Controlling bythe userApplication and use of our units in the target products is outside of our control andtherefore lies exclusively in the area of responsibility of the user.Use under spe-cial conditionsThe used semiconductors and components of KEB are developed and dimensio-ned for the use in industrial products. If the KEB COMBIVERT is used in machi-nes, which work under exceptional conditions or if essential functions, life-sup-porting measures or an extraordinary safety step must be fulfi lled, the necessaryreliability and security must be ensured by the machine builder.1.2 Qualifi cationAll operations serving transport, installation and commissioning as well as maintenance are to be carried outby skilled technical personnel (observe IEC 364 or CENELEC HD 384 or DIN VDE 0100 and national accidentprevention rules!). According to this manual qualified staff means:- those who are able to recognise and judge the possible dangers based on their technical training and experience- those with knowledge of the relevant standards and who are familiar with the fi eld of power transmission(VDE 0100, VDE 0160 (EN 50178), VDE 0113 (EN 60204) as well as the approporiate regulations for yourarea.Danger by highvoltageKEB electronics components contain dangerous voltages which can cause death orserious injury. In operation, drive converters, depending on their degree ofprotection, may have live, uninsulated, and possibly also moving and hotsurfaces.In case of inadmissible removal of the required covers, of improper use, wronginstallation or maloperation, there is the danger of serious personal injury anddamage to property.
