These requirements cover robots and robotic equipment rated 600 V or less and intended for installation in accordance with the National Electrical Code, ANSI/NFPA 70. Since end-use installation of a robot and robotic equipment may vary for each user application, guidelines for end-product installation may be evaluated to the applicable sections of ANSI/RIA R15.06, Standard for Industrial Robots and Robot Systems-Safety Requirements. Portions of the requirements in this Standard have been excerpted from the Robotic Industries Associations (RIA) Standard for Industrial Robots and Robot Systems - Safety Requirements, ANSI/RIA R15.06. These requirements cover robotic equipment and systems intended for indoor and outdoor use in applications such as parts assembly, parts transfer, automated material handling, inspection, loading, diecasting, deburring, welding, paint spraying, clinical/diagnostic systems, pharmaceutical applications, commercial food processing, automated vehicle refueling systems, library book handling/sorting, clean room applications, medical use for surgery, mobile robots, automated guided vehicles, automated storage/retrieval systems, and the like. Unique features or functions associated with the robotic application, not specifically addressed in this Standard, shall also be evaluated to other applicable Standards/requirements. These may include, but are not limited to, Electrical Equipment for Laboratory Use; Part 1: General Requirements, UL 3101-1; Medical and Dental Equipment, UL 544; Power Operated Pumps for Petroleum Product Dispensing Systems, UL 79. In addition to the requirements in this Standard, robots and robotic systems shall also comply with the applicable sections of the Electrical Standard for Industrial Machinery, ANSI/NFPA 79. Robots and robotic systems intended for use in hazardous locations, as defined by the National Electrical Code ANSI/NFPA 70, shall also comply with the requirements in Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, II, and III, Division 1, Hazardous (Classified) Locations, UL 913. In the following text, a requirement that applies to one type of equipment, such as a controller or teach pendant, will be identified by a specific reference. In the absence of a specific reference or if the term robot or robotic equipment is employed, it is to be understood that the requirement applies to all types of equipment covered by this Standard.
These requirements cover inverters ,converters ,charge controllers ,and output controllers intended for use in stand-alone(not grid connected) or utility-interactive (grid-connected) power systems .Utility-interactive inverters and converters are intended to be installed in parallel with an electric supply system or an electric utility to supply common loads.
