E-PAK 150 DX/300 DX/500 DXEN28for installation. Only trained personnel familiar with these standards isallowed to handle this type of filters.• This unit was specially designed to comply with official regulationsconcerning the risk of explosion. If improperly used, incorrectly installed,or altered, no matter to which extent, the safety and reliability could bejeopardized.• For E-PAK 150 DX/300 DX/500 DX to function properly and fulfil thenecessary safety requirements as stated in the declaration of conformity,the complete system is to be assessed with regards to applicable safetystandards and directives and comply with all requirements described inthis document.• The designer of the system as a whole, has to guarantee the correctfunction of all interacting products or components and ensure that thecomplete system meets all necessary safety requirements.• Only authorized personnel is allowed to have access to this unit.• The filter is not to be used for filtering fumes from weldingprocesses.4.1 Explosion protectionThe CE and ATEX markings on this unit ensure both a high level of safety andprotection against ignition of the collected combustible dust. However, if anexplosion occurs due to misuse, insufficient maintenance or faulty installation,this unit is equipped with additional protection methods to avoid dangerouspressure build-up in the filter.E-PAK 150 DX/300 DX/500 DX is equipped with either an explosion reliefpanel, see Section 4.1.1 Method 1: Explosion relief venting, or an explosionsuppression system, see Section 4.1.2 Method 2: Explosion suppression system.The suppression system is normally only used if venting is impossible due tothe location of the filter, dangerous material properties or a resulting flame.4.1.1 Method 1: Explosion relief ventingThe harmful effects of an explosion are minimized by venting the pressureand flame of the explosion through an explosion relief panel. In case of anexplosion, the resulting flame and pressure escape through the explosion reliefpanel which is to be directed towards a safe area without any people. This areais referred to as the ‘risk area’.The risk area is to be clearly marked, for example with a fence, warning linesand signs, and entry is prohibited when the filter is in operation. The area is tobe free of any flammable or combustible material or other objects which maybe damaged by the flames and explosion pressure.The general size of the risk area is shown in Figure 6. The followingdimensions apply:• A=8 m (26.2 ft)• B=2 m (6.6 ft)• C=3.5 m (11.5 ft) or ground level, if elevated• D=4 m (13.1 ft)
