General Notes How to use the operating instructions 1 1 General Notes 1.1 How to use the operating instructions The operating instructions are an integral part of the product and contain important in- formation on operation and service. The operating instructions are written for all employ- ees who assemble, install, startup, and service this product. The operating instructions must be accessible and legible. Make sure that persons re- sponsible for the system and its operation, as well as persons who work independently on the unit, have read through the operating instructions carefully and understood them. Consult SEW-EURODRIVE if you have any questions or if you require further informa- tion. 1.2 Structure of the safety notes The safety notes in these operating instructions are structured as follows: Symbol SIGNAL WORD! Nature and source of hazard. Possible consequence(s) if disregarded. • Measure(s) to avoid the hazard. Symbol Signal word Meaning Consequences if disregarded Example: HAZARD! Imminent hazard Severe or fatal injuries WARNING! Possible hazardous situation Severe or fatal injuries General hazard CAUTION! Possible hazardous situation Minor injuries Specific hazard, e.g. electric shock NOTE ON Possible damage to property Damage to the drive system or its environ- EXPLOSION ment. PROTECTION STOP Possible damage to property Damage to the drive system or its environ- ment. NOTE Useful information or tip. Simplifies handling of the drive system.
