ATEX DIRECTIVE AND CLASSIFICATION SYSTEMSince 2003, manufacturers across the European Union (EU)have been obliged to comply with strict new EU directivesgoverning safety in explosive atmospheres. Called ATEX (fromthe French ATmosphères EXplosives), ATEX Directive 94/9/EChas an impact not only on European manufacturers, but alsoon non-European makers of industrial equipment wishing tosell in Europe.Two of the most common classification systems for hazardouslocations are the Zone Classification system used by theEuropean Union (EU) and the International ElectrotechnicalCommission (IEC), and the NEC Division Classification system.Articles 505 and 506 of the NEC refer to zone classifications.Refer to the Technical Information section of the Specifier’sGuide for specific definitions and additional information.HOFFMAN’s ATEX enclosures are not intended for use inexplosion-proof or flame-proof (Ex d) applications.ATEX MARKING DIRECTIVE (94/9/EC)II2European allyIEC / EUZone 0Zone 1Zone 2NEC 505Zone 0Zone 1Zone 2NEC 500Division 1CEC Section18Zone 0CEC Annex JDivision 1Division 2Zone 1Zone 2Division 2IEC classification per IEC 60079-10EU classification per EN 60079-10US classification per ANSI/NF PA 70 National Electrical Code (NEC)Article 500 or Article 505CA classification per CSA C22.1 Canadian Electrical Code (CEC) Section18 or Annex JZONESGEquipmentCategoryAREA CLASSIFICATIONDGasSAFE AREAZONE 2 /22DustZONE 1 / 21ExeIIT6European ExplosiveAtmosphere ProtectionConceptProtectionMethodGas GroupTemperatureClassZONE 0 / 20ZONE 0 / 20ZONE 0 / 20Permanently or frequently hazardous over longperiodsZONE 1 / 21Occasionally hazardousZONE 2 / 22Rarely or temporarily hazardousZones 20, 21 and 22 are dustINCREASED SAFETY “EX E”ounSngexy IECEX populated enclosures require IECEX certifiedcomponents specifically listed in Certification (see IECEX SIR09.0100 for more detail)/O ATEX and intrinsically safe certified terminal blocks can beinstalled in populated enclosuresAirNOTES:All three elements ofthe FIRE TRIANGLEmust be present forignition to occur.itio No components or parts temperatures exceed the temperaturelimit of the corresponding temperature classIgn There are no arcs or sparksrceIt is assumed that the hazardous atmosphere penetrates to theenclosure interior and explosion is prevented by ensuring thateither in normal operation or under fault conditions:Flammable/Combustible Substance Contact your local HOFFMAN sales office or distributor forcomplete informationnVent.com/HOFFMAN 5

R Combined Terminal Resistance FactorEXAMPLE:This factor is used to determine the number of terminalsthat can be accommodated within the enclosure withoutexceeding the enclosure maximum wattage rating. Thecombined terminal resistance factor (R) is the sum of theindividual terminal resistances (Rt) and the resistance of thecable core equal in length to the enclosure maximum diagonal(Rw). The core resistance has been defined in the standard BSEN 60228.A customer wants to determine the number of WDU 2.5terminals that could be used in an EXE300300150SS61Eenclosure rated at 17.5 watts (P) and at 10 amps (I).Solving for N in the above formula N P / (R x I2):N 16.5 / (0.00345 x 102)N 47The maximum physical number of WDU 2.5 terminals thatcan be installed on a single rail is 29 and a total of 3 railscan be installed in the enclosure, therefore two rows of 23terminal blocks could be accommodated in the enclosure.
