4 1 General The uid product has been designed, manufactured and tested using harmonised standards and directives generally applicable in the European Union and left the plant in a safe and fault-free condition. To maintain this condition and ensure safe operation, operators must observe the information and warnings in this operating and maintenance manual. The uid-technical product must only be installed and integrated into a hydraulic system by a quali ed technician, who is familiar with and works the generally accepted engineering standards and the latest legal regulations and standards of explosion protection. Furthermore, the special features of the application and/or operation environment must be carefully assessed and taken into account. 2 Identification Name and address of manufacturer Headquarter HAWE Hydraulik SE Streitfeldstr. 25 D München PO Box D München Tel Fax: info@hawe.de Device type and manufacturing date: Reference number for technical documentation: see type plate on request 4/7 B HAWE Hydraulik SE

5 3 Use In the directive2014/34/ the uid product is assigned to equipment group II category 2 and category 3 or equipment group I category M2 and can be used in zones 1, 2, 21, 22 in accordance with 1999/92/EC or in zone M2. The equipment is intended for use in areas where there are explosive gas/air and/or dust/air mixtures, mists or vapours. In accordance with DIN EN and DIN EN the uid product is assigned to the type of protection "c" with a maximum surface of 120 C, or class T4. The standard DIN EN and corresponding parts of this series of standards apply for the solenoids. -compliant solenoids and displacement transducers may only be operated using product-speci c operating and maintenance manuals and in the permissible ambient range. Around the world, other certificates and unit approval tests are regionally required in addition to. For a rough map, see Chapter 2, "Identification". Note For a precise list of all order codings and the assigned classifications, see Chapter 8, "Tables: order coding, classification and usage". 4 Assembly, installation and disassembly The uid product is to be attached to a level mounting surface. Commercially available, -compliant (if applicable) connecting elements ( ttings, hoses, tubes, etc.) from reputable manufacturers should be used to integrate the product into the hydraulic system. The hydraulic system must be decommissioned and depressurised in line with regulations (particularly in the case of systems with hydraulic accumulators) before removing the product. In this regard, also see the notes in General operating manual for the assembly, initial operation and maintenance of hydraulic components and systems: B 5488 HAWE Hydraulik SE B /7

6 5 Initial operation and settings Operation of uid-technical products is only permissible if installed mounting regulations. The device must be separately connected to ground in case dangerous potential differences occur (e.g. with insulated mounting) and if it is not guaranteed that the uid-technical piping system will establish a reliable connection to those components that are connected to ground.the manufacturer will generally deliver the device with the settings applied. Alternatively, the customer can also apply or adjust these settings. In this case the customer must refer to the instructions provided in the valid documentation for the speci c device. In this regard, also see the notes in General operating manual for the assembly, initial operation and maintenance of hydraulic components and systems: B Maintenance, service and troubleshooting The uid-technical product requires almost no maintenance. All hydraulic connections must be checked regularly - at least once every year - for possible damages (visual check). In case of external leakage the system must be taken out of operation and repaired. The user has to make sure that possibly vaporized ingredients of the escaped pressure uid do not cause any danger when blended with surrounding explosion hazardous atmosphere. The use of re inhibiting uids or mechanical shielding is recommended in such cases. The surface of the device must be checked regularly - at least once every year - for dust deposits, which should then be cleaned off. The product-speci c technical documentation speci es any other necessary maintenance work required to ensure safe and stable operation of the device. It is assumed that the generally known and applicable recommendations for service and operation of hydraulic systems are complied with. In this regard, also see the notes in General operating manual for the assembly, initial operation and maintenance of hydraulic components and systems: B /7 B HAWE Hydraulik SE

7 7 Safety notes 7a) General In addition to the EC Directive 2014/34/ and the national transpositions (the Product Safety Act (Produktsicherheitsgesetz, ProdSG) in Germany), EC [Standards number/designation] ( operational directive) and its transpositions (in Germany the Industrial Safety Regulation (Betriebssicherheitsverordnung, BetrSichV)) apply in particular for operators. In case the uid-technical product shows any signs of a defect, malfunctioning or external damage (including corrosion), the device must be taken out of operation immediately. Any deposits on the surface of the device must be avoided and must not obstruct heat emission. It is the user s duty to ensure free and unhindered heat emission during operation. This means that the device must neither be covered or stored immediately adjacent to heat sources during operation. Care is to be given that the device is not subjected to direct sunlight during operation. Caution Danger of burning due to hot metal surfaces! Risk of minor injury. Wear gloves. Allow the device to cool down for at least 10 minutes before touching it. The type plate / type stamping must not be removed/painted over, to ensure legibility and retain -approval. Color coating without giving notice to the manufacturer is forbidden. All electrical lines must be xed and a min. bending radius of 110 mm must be maintained. 7b) Product-speci c Single pumps, cover plate versions and power packs: In accordance with DIN EN and DIN EN item 5.4, in terms of content, moving parts which are protected by being immersed in a uid are sufficiently protected against ignition from the atmosphere through the arrangement of a monitoring element (e.g. level gauge, level switch) that displays any non-permitted loss of protective uid (this means pumps are to be operated in an oil-submerged arrangement). Any non-permitted heating of the protective uid is to be monitored by a switch (DIN EN ) for further safety. Furthermore, for the self-installation of pumps in tank containers, an -compliant coupling must be used. Pressure switches and directional spool valves with contact switches: Pressure switches in accordance with D 5440 and directional spool valves with contact switches for switching position monitoring are simple electrical operating media in the sense of DIN EN , subchapter 5.7, which do not have to be provided with any special marking. They can be operated in potentially explosive atmospheres in an intrinsically safe circuit (with isolation switch amplifier) and are assigned to class T6 in Group II. We recommend devices from PEPPERL + FUCHS GmbH, Mannheim, Germany, or from BARTEC, Menden, Germany, as isolation switch ampli ers. Hydraulic accumulators: Hydraulic accumulators do not have a heating system. Their surface depends on the operation condition and the of the pressure uid. A re-check of the max. surface, based on the customer specifications for working conditions, will be undertaken by the manufacturer on the product and will be documented. Intrinsically save components: Components with a solenoid classification O I M2 Ex d ib I ful l this classification only if used in combination with a ib - power supply of category M2. Note The classification of the type of protection is only valid if it is not restricted through the use of the device with other components (e.g. on a hydraulic power pack or with integration into a complete system) and their lower classification. In this case, the lowest classification applies. If necessary, the operating and maintenance manual for the electromagnet and its classification must be observed. Failure to comply with these regulations will result in loss of warranty claims against HAWE Hydraulik. HAWE Hydraulik SE B /7
