35、THOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 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

36、application, guidelines for end-product installation may be evaluated to the applicable sections of the Robotic Industries Association (RIA) Standard for Industrial Robots and Robot Systems Safety Requirements, ANSI/RIA R15.06. 1.2 These requirements cover robotic equipment and systems intended for

37、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,

38、library book handling/sorting, clean room applications, medical use for surgery, mobile robots, automated guided vehicles, automated storage/retrieval systems, and the like. 1.3 Robots and robotic equipment that contain unique features or functions associated with the application or end-product equi

39、pment, and not specically addressed in this Standard, shall also be evaluated to the requirements of the other applicable Standards. 1.4 In addition to the requirements in this Standard, robots and robotic systems shall also comply with the applicable sections of the Electrical Standard for Industri

40、al Machinery, ANSI/NFPA 79. 1.5 Robots and robotic systems intended for use in hazardous locations, as dened by the National Electrical Code, ANSI/NFPA 70, shall also comply with the applicable safety requirements based on the specic end-use application, including those contained in the following st

41、andards: a) Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, II, and III, Division 1, Hazardous (Classied) Locations, UL 913; b) Deleted c) Explosion-Proof and Dust-Ignition-Proof Electrical Equipment for Use in Hazardous (Classied) Locations, UL 1203; d) Nonincendive Electr

42、ical Equipment for Use in Class I and II, Division 2 and Class III, Divisions 1 and 2 Hazardous (Classied) Locations, ISA 12.12.01; e) Electric Motors and Generators for Use in Hazardous (Classied) Locations, UL 674; and f) Purged and Pressurized Enclosures for Electrical Equipment, NFPA 496. 1.5 re

43、vised January 7, 2015 1.6 In the following text, a requirement that applies to one type of equipment, such as a controller or teach pendant, will be identied by a specic reference. In the absence of a specic reference or if the term robot or robotic equipment is employed, it is to be understood that

44、 the requirement applies to all types of equipment covered by this Standard.

45、g denitions apply. 2.2 AUTOMATIC OPERATION (AUTO MODE) The time when a robot is performing its programmed tasks through continuous program execution. 2.3 AWARENESS SIGNAL A device that warns a person of an approaching or present hazard by an audible or visible means. A visible means could include a

46、text message or display on a teach pendant or user interface screen. 2.4 CLASS 2 SYSTEM A circuit, transformer, or power source having energy- and voltage-limiting characteristics as described in the Standard for Low Voltage Transformers Part 3: Class 2 and Class 3 Transformers, UL 5085-3. 2.5 CONTR

47、OLLED ENVIRONMENT An environment relatively free of contaminants. A controlled environment may also be provided by means of a NEMA Type 4, 12 or 13 enclosure as specied in the Standard for Industrial Control Equipment, UL 508. 2.6 DRIVE POWER The source or means of supplying energy to the robot actu

48、ators to produce motion. 2.7 EMERGENCY STOP A method using hardware-based components that override all other robot controls and removes drive power from the robot actuators and brings all moving parts to a stop. 2.8 ENABLING DEVICE A manually operated device which, when continuously activated, permi

49、ts motion. Releasing the device shall stop robot motion and motion of associated equipment that may present a hazard. 2.9 END-EFFECTOR An accessory device or tool specically designed for attachment to the robot wrist or tool mounting plate to enable the robot to perform its intended task. (Examples may include gripper, spot weld gun, arc weld gun, spray paint gun, or any other application tools.) 2.10 FIELD-WIRING TERMINAL A wiring terminal on permanently connected equipment
