ILME: APX Gehäuse aus Aluminiumdruckguss - APV ATEX

16 When other Ex certified components are fitted in the enclosure, it is essential to take into account all applicable limitations indicated on the respective certificates. When installing the components, observe the minimum insulation distances (surface and air) prescribed for the target application. Ensure that the maximum operating temperature (sum of the ambient temperature and the potential heat generated by non-sparking equipment in the box) is equivalent to T ≤ 85 °C . For wall-mounting, use the slots on the external surface of the product only (see Figure 2). The hole to be used to connect the enclosure to the earth conductor is on one of the external walls: use the screw with washer and the lug supplied, as shown in Figure 2 . The recommended tightening torque is 1.8 Nm. Perform the equipotential connection between the bottom of the box and the cover using the screws and inserts supplied. The tightening torque is 2 Nm. Figure 2 - Detail of the installation of the external equipotential grounding connection OPERATION AND PERIODICAL MAINTENANCE Periodical maintenance is essential to ensure that the enclosure is in good working order and able to provide the required protection degree. Do not open the enclosure (that is, do not loosen the cover screw) in the presence of explosive atmospheres : the components inside the enclosure may be very hot! In this case, it is necessary to allow the enclosure to cool down for a sufficient amount of time and, in the presence of explosive atmospheres, always disconnect the installation upstream before loosening the cover screws. Potential risk of accumulation of electrostatic charges In areas where combustible dust is present, it is essential to clean the surface of the upper wall of the enclosure on a weekly basis with a damp cloth only, to prevent the deposited dust from reaching a thickness above 5 mm. Always check the conditions of the gasket when opening the enclosure . Verify that the closing screws are correctly positioned and tightened when closing the enclosure. Once a year, verify that the wall-mounting screws/bolts are correctly tightened and free from corrosion. Once a year, check the tightness of the cable glands (condition of the gaskets). Once a year, verify that there are no visible damages on the enclosure . If the parts are damaged or no longer able to guarantee an Ex protection degree, replace the faulty part with a new one (for example the cable gland or the whole box). DISPOSAL The product must be disposed of in accordance with national laws and regulations concerning the disposal and recycling of industrial waste. Products are compliant with Directive RoHS 2002/95/EC and subsequent amendments. CE MARKING The CE marking on the box cover indicates that the product complies with the Low Voltage Directive 2006/95/EC.
