Automation and safety engineering are closely related. Engineering, installation and operation of complex automation solutions are greatly simplified by integrated safety-related functions and modules. Usually, the safety engineering requirements depend on the application. The level of the requirements results from, among other things, the risk and the hazard potential arising from the specific application and from the applicable standards and regulations. The goal of designing machines safely is to protect people. The risk associated with machines with electrically controlled drives comes chiefly from moving machine parts and electricity itself. Only you, the user, machine builder, or system integrator can be aware of all the conditions and factors realized in the design of your application for the machine. Therefore, only you can determine the automation equipment and the related safeties and interlocks which can be properly used, and validate such usage. Hazard and Risk Analysis The standard IEC 61508 "Functional safety of electrical/electronic/programmable electronic safety-related systems" defines the safety-related aspects of systems. Instead of a single functional unit of a safetyrelated system, the standard treats all elements of a function chain as a unit. These elements must meet the requirements of the specific safety integrity level as a whole. The standard IEC 61800-5-2 "Adjustable speed electrical power drive systems – Safety requirements – Functional" is a product standard that defines the safety-related requirements regarding drives. Among other things, this standard defines the safety-related functions for drives. Based on the system configuration and utilization, a hazard and risk analysis must be carried out for the system (for example, according to EN ISO 12100 or EN ISO 13849-1). The results of this analysis must be considered when designing the machine, and subsequently applying safety-related equipment and safetyrelated functions. The results of your analysis may deviate from any application examples contained in the present or related documentation. For example, additional safety components may be required. In principle, the results from the hazard and risk analysis have priority. The EN ISO 13849-1 Safety of machinery - Safety-related parts of control systems - Part 1: General Principles for Design describes an iterative process for the selection and design of safety-related parts of controllers to reduce the risk to the machine to a reasonable degree. WARNING NON-CONFORMANCE TO SAFETY FUNCTION REQUIREMENTS  Specify the requirements and/or measures to be implemented in the risk analysis you perform.  Verify that your safety-related application complies to applicable safety regulations and standards.  Make certain that appropriate procedures and measures (according to applicable sector standards) have been established to help avoid hazardous situations when operating the machine.  Use appropriate safety interlocks where personnel and/or equipment hazards exist.  Validate the overall safety-related function and thoroughly test the application. Failure to follow these instructions can result in death, serious injury, or equipment damage. WARNING UNINTENDED EQUIPMENT OPERATION  Perform a hazard and risk analysis to determine the appropriate safety integrity level, and any other safety requirements, for your specific application based on all the applicable standards.  Ensure that the hazard and risk analysis is conducted and respected according to EN/ISO 12100 during the design of your machine. Failure to follow these instructions can result in death, serious injury, or equipment damage.
