IEC 60335-2-97:2023 deals with the safety of electric drives for shutters, blinds and awnings, intended for household and similar purposes, their rated voltage being not more than 250 V for single-phase drives and 480 V for other drives, including direct current (DC) supplied appliances and battery-operated appliances. Examples of equipment that can be driven are – spring controlled folding arm awnings; – curtains; – grilles covering doors and windows; – projection screens; – shutters covering doors and windows; – draperies. Drives can be supplied with a driven part. Drives not intended for normal household use but that nevertheless can be a source of danger to the public, such as drives intended to be used by laymen in shops, in light industry, on farms and on industrial premises, are within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by drives that are encountered by all persons in and around the home. However, in general, it does not take into account – persons (including children) whose physical, sensory or mental capabilities; or lack of experience and knowledge prevents them from using the drive safely without supervision or instruction; – children playing with the drive. For appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary. In many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities. This standard does not apply to – drives intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas); – drives for vertically moving garage doors for residential use (IEC 60335-2-95); – drives for gates, doors and windows (IEC 60335-2-103); – drives used in premises such as hangars or in heavy industry; – drives for theatre curtains. This fourth edition cancels and replaces the third edition published in 2016 and Amendment 1: 2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the text has been aligned with IEC 60335-1:2020; b) scope includes DC-supplied appliances and battery-operated appliances (Clause 1); c) some notes have been converted to normative text (Clause 1, 5.10, 20.101, 20.103); d) use of artificial loads is introduced (5.10); e) application of test probe 19 has been introduced (8.1.1, 20.2); f) addition of surface temperatures for external accessible surfaces (11.3, 11.8); g) requirements are added for drives intended for permanent connection delivered with a connector to ease the installation (22.102, 24.1.101, 25.3); h) clarification for connectors that are non-detachable once engaged (24.1.5). i) added requirements for instructions for parts of class III construction supplied from a detachable power supply part (7.12, 7.12.1). This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments unless that edition precludes it; in that case, the latest edition that does not preclude it is used. It was established on the basis of the sixth edition (2020) of that standard. LIEC 60335-2-97:2023 traite de la securite des motorisations electriques pour les volets, les rideaux et les stores pour usage domestique et analogue, dont la tension assignee est inferieure ou egale a 250 V pour les motorisations monophasees et a 480 V pour les autres motorisations, y compris les appareils alimentes en courant continu et les appareils alimentes par batteries. Des exemples dequipements qui peuvent etre motorises sont: – les stores bannes a ressorts; – les rideaux; – les grilles qui protegent les portes et les fenetres; – les ecrans de projection; – les volets qui protegent les portes et les fenetres; – les draperies. Des exemples sont representes a la Figure 101. Les motorisations peuvent etre livrees avec une partie entrainee. Les motorisations qui ne sont pas destinees a un usage domestique normal, mais qui neanmoins peuvent constituer une source de danger pour le public, telle que les motorisations destinees a etre utilisees par des utilisateurs non avertis dans des magasins, chez des artisans, dans des fermes et dans des locaux industriels, sont comprises dans le domaine dapplication de la presente norme. Dans la mesure du possible, la presente norme traite des dangers ordinaires presentes par les motorisations, encourus par toutes les personnes a linterieur et autour de lhabitation. Cependant, elle ne tient pas compte en general – des personnes (y compris des enfants) dont les capacites physiques, sensorielles ou mentales; ou le manque dexperience et de connaissance les empechent dutiliser la motorisation en toute securite sans surveillance ou instruction; – de lutilisation de la motorisation comme jouet par des enfants. Pour les appareils destines a etre utilises dans des vehicules ou a bord de navires ou davions, des exigences supplementaires peuvent etre necessaires. Dans de nombreux pays, des exigences supplementaires sont specifiees par les organismes nationaux de la sante, par les organismes nationaux responsables de la protection des travailleurs, par les organismes nationaux responsables de lalimentation en eau et par des organismes similaires. La presente norme ne sapplique pas – aux motorisations destinees a etre utilisees dans des locaux qui presentent des conditions particulieres, telles que la presence dune atmosphere corrosive ou explosive (poussiere, vapeur ou gaz); – aux motorisations de portes de garage a ouverture verticale pour usage residentiel (IEC 60335-2-95); – aux motorisations de portails, portes et fenetres (IEC 60335-2-103); – aux motorisations utilisees dans des locaux tels que les hangars davions ou dans lindustrie lourde; – aux motorisations p
