3 Switches compliant with ATEX directive / Technical concepts ATEX Directive The ATEX mark ( Atmospheres Explosives) refers to two European directives concerning the risk of deflagration in potentially explosive atmospheres: - ATEX 94/9/EC: concerns the requirements for electrical and non-electrical equipment used in potentially explosive environments. According to this directive the manufacturer has to comply with the provided requirements and mark the articles in conformity with particular categories - ATEX 99/92/EC: regards the minimum safety and sanitary requirements that the user has to satisfy during the activity in potentially explosive environments. These directives determine the requirements for the safety and health protection of people, animals and property and carry several procedures for the conformity demonstration of equipment to the directive requirements. Classification of potentially explosive atmospheres. A potentially explosive atmosphere is an atmosphere that could become explosive according to the local conditions of work. Usually it consists in environments where it is present a mixture of air and flammable substances in the form of gas, smog, steams and dusts. The ATEX 99/92/EC directive defines for two types of explosive atmosphere, depending on the presence in the zone of gases or combustible dusts. Each area exposed to these types of explosive atmospheres is classified in three zones, according to the frequency and duration of the explosive atmosphere. For atmospheres with explosive gas, areas are classified in zones 0, and 2; for atmosphere with explosive dusts in zones, 2 and : - Zone 0/ : a place where gas or combustible dust is present permanently. Constant danger. Equipment of minimum category is required. - Zone /2 : a place where gas or combustible dust is likely to occur during normal operation. Potential danger. Equipment of minimum category 2 is required. - Zone 2/ : a place where gas or combustible dust is unlikely to occur or only for a short period. Lower danger. Equipment of minimum category 3 is required. It s under the responsibility of the final user to choose and classify the different zones and to use suitable equipments. Device categories acc. to ATEX directive and IEC standards ATEX 94/9/CE directive distinguishes equipment between two main groups: - Group I: equipment and systems for mining - Group II: equipment and systems for all other applications Equipment of the group I is divided in two further categories according to the required protection degree: - Category M: Equipment designed to assure a very high protection level - Category : Equipment designed to assure a high protection level Equipment of the group II is divided in three further categories according to the required protection degree: - Category : Equipment designed to assure a very high protection level (use in zones 0 and, and 2, 2 and ) - Category 2: Equipment designed to assure a high protection level (use in zones and 2, 2 and ) - Category 3: Equipment designed to assure a normal protection level (use in zones 2 and ) The relation between the EPL (Equipment Protection Levels) of the IEC 09-0 standard, and the categories and applications of the ATEX directive are shown in the table below. Table Classification of the environment and device according to ATEX directive and IEC 09 0 standard Environment characteristics Equipment characteristics Environment of application Flammable material Potentially explosive atmosphere Classification of potentially explosive atmospheres: ZONE acc. to ATEX 94/9/EC Required marking of the device: CATEGORY Required marking of the device: GROUP acc. to IEC 09-0 EPL Required protection level Mining M Ma I Mb high very high It is present continuously, for long periods or frequently 0 G Ga very high Gas It is likely to occur 2G Gb high Above ground It is unlikely to occur or, if it does, is likely to do infrequently and for a short period only 2 3G Gc normal II It is present continuously, for long periods or frequently D Da very high Dusts It is likely to occur 2 2D Db high It is unlikely to occur or, if it does, is likely to do infrequently and for a short period only 3D Dc normal General Catalogue -

4 Protection modes In order to avoid an explosion caused by the electrical ignition of an explosive atmosphere, it is possible to take different type of precautions: - Isolate the dangerous parts into housing in order to limit the explosion inside itself. - Avoid contact between ignition sources and the potentially explosive atmosphere interposing solid, liquid or gaseous materials. - Take measures in order to limit the generation of dangerous ignition sources, eliminating the possibility of faults or limiting the energy so it s not sufficient to cause the ignition. For each modality several methods of protection have been developed and standardized, as listed in the following table.

Adjustable levers Overturning levers Orientable heads In the switches it is possible to adjust the lever with 0 steps for the whole 3 range. The positive movement transmission is always guaran0 teed thanks to the particular geometrical coupling between the lever and the revolving shaft as prescribed for safety applications by the German standard BG-GS-ET-. In the switches, the lever can be fastened straight or reversed, maintaining the positive coupling. This makes it possible to have two different work plans of the lever. In all switches, it is possible to rotate the head in 90 steps. Unidirectional heads For switches with swivelling lever, it is possible to select the unidirectional operation by removing the four screws of the head and revolving the internal plunger.
