4 Introduction 4 Industrial Hydraulics Bosch Rexroth AG Be on the Safe Side with Rexroth as your Partner for Industrial Hydraulics Our products are manufactured and delivered strictly observing the ATEX Directive. Due to detailed analyses, risks in design, production and operation are recognized in due course and ruled out right from the beginning. Our products therefore comply with the very stringent safety and health requirements laid down in Directive 94/9/EC. To ensure compliance with these high standards, new processes were integrated in our production sequence, or existing processes revised and updated. < Risk analysis and conformity assessment procedures < Type tests < Quality assurance with process representation and ensured traceability of products < Issue of a declaration of conformity, CE marking and Ex marking < Creation and provision of operating instructions for components, devices and power units < Filing of design documentation with notified bodies < Nomination of an explosion protection officer Group I (mines, firedamp / combustible dusts) Group II (explosive atmospheres consisting of gas/air or dust/air mixtures, mists or vapors) Category M Category 1 Category 2 Category For equipment that ensures a very high level of protection Operation is ensured also in the rare case of incidents. Two independent means of protection, or functioning ensured if two faults occur dependently of each other. For equipment that ensures a high level of protection. Shutdown possible in the event of an explosive atmosphere. Suitable for normal operation and more severe operating conditions. G (gas; zone 0) D (dust; zone 20) For equipment that ensures a very high level of protection. Intended for the case of an expected permanent, frequent or long-term explosive atmosphere. Two independent means of protection, or functioning ensured if two faults occur independently of each other. No ignition sources even with rare faults. G (gas; zone 1) D (dust; zone 21) For equipment that ensures a high level of protection. Intended for the occasional occurrence of an explosive atmosphere. No ignition sources even with faults that regularly occur. G (gas; zone 2) D (dust; zone 22) For equipment that ensures the normal level of protection. Intended for the rare case that explosive atmospheres are unlikely to occur, or if they do occur are likely to do so far a short period only. No ignition sources during normal operation.

5 Bosch Rexroth AG Industrial Hydraulics 5 Einleitung Safety, Health and Quality To meet the exacting demands placed on health and safety of employees and to guarantee quality, comprehensive technical documentation has been produced. Each component is accompanied by a documentation package that includes the following items. < Written operating instructions in four languages and a CD-ROM with all further EU languages < General information about the use of equipment in potentially explosive atmospheres < Product data sheet < Product-specific instructions together with compulsory declaration of conformity The required technical product data sheets are, of course, also available online. Servicing and repair of equipment according to the old Directive is still permitted in the EU and worldwide. This is carried out quickly and competently by our Service Centers. Labour intensive and costly processes of this type can only be handled by a manufacturer such as Rexroth. Benefit from our know-how and the experience of our Product Units. The Conformity Assessment Procedure Depending on the category and equipment group, the following requirements must be met: Category to 94/9/EC Type of product Procedure Storing of documentation IM2/II2G/II2D IM2/II2G/II2D IM2/II2G/II2D II3G/II3D electrical and non-electrical electrical non-electrical electrical and non-electrical EC type testing by notified body EC type testing by notified body Conformity assessment by manufacturer Conformity assessment by manufacturer Rexroth + to notified body with confirmation Rexroth + to notified body with confirmation Rexroth + to notified body Rexroth
