4 Industrial Hydraulics Bosch Rexroth AGIntroduction
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.

Shutdown pos-sible in the event of an explosive atmosphere.
Intended for the case of an expect-ed permanent, frequent or long-term
explosive atmosphere.
Intended for the occasional occur-rence of an explosive atmosphere.
Intended for the rare case that ex-plosive atmospheres are unlikely to occur, or if they do occur are likely to do so far a short period only.
Two independent means of protec-tion, or function-
ing ensured if two faults occur dependently of
each other.
Suitable for normal operation and more severe operating condi-
tions.
Two independent means of protec-tion, or functioning ensured if two faults occur independently of each
other.No ignition sources even with rare
faults.
No ignition sources even with faults that regularly occur.
No ignition sources during normal operation.

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 compo-nent 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:
