5 ATEX Directive and Classification System Since 2003, manufacturers across the European Union (EU) have been obliged to comply with strict new EU directives governing safety in explosive atmospheres. Called ATEX (from the French ATmosphères EXplosives), ATEX Directive 94/9/EC has an impact not only on European manufacturers, but also on non-european makers of industrial equipment wishing to sell in Europe. Two of the most common classification systems for hazardous locations are the Zone Classification system used by the European Union (EU) and the International Electrotechnical Commission (IEC), and the NEC Division Classification system.

R Combined Terminal Resistance Factor This factor is used to determine the number of terminals that can be accommodated within the enclosure without exceeding the enclosure maximum wattage rating.

The core resistance has been defined in the standard BS EN 60228.

10 R Combined Terminal Resistance Factor This factor is used to determine the number of terminals that can be accommodated within the enclosure without exceeding the enclosure maximum wattage rating. The combined terminal resistance factor (R) is the sum of the individual terminal resistances (Rt) and the resistance of the cable core equal in length to the enclosure maximum diagonal (Rw). The core resistance has been defined in the standard BS EN Wattage to be Dissipated (P) = N x R x I² Total Number of Terminals (N) Combined Terminal Resistance Factor (R) = (Rt + Rw) the sum of terminal resistance [Rt] and wire resistance [Rw] Maximum Current (amps) used in the application = (I) Example: A customer wants to determine the number of WDU 2.5 terminals that could be used in an EXE SS61E enclosure rated at 17.5 watts (P) and at 10 amps (I). Solving for N in the above formula N = P / (R x I 2 ): N = 16.5 / ( x 10 2 ) N = 47 The maximum physical number of WDU 2.5 terminals that can be installed on a single rail is 29 and a total of 3 rails can be installed in the enclosure, therefore two rows of 23 terminal blocks could be accommodated in the enclosure.

11 ATEX-certified accessories Large-Volume ATEX Purge System Type Y, Z and Ex [pz] Designed to supply one or more enclosures with a protective gas supply, Hoffman s Ex [pz] purge system is designed and certified according to European requirements of ATEX Directive 94/9 EC and EN for Type Ex [pz] applications. ATEX-certified Ex [pz] purge systems reduce the classification in the protected enclosure from Zone 2 to nonhazardous, allowing the use and operation of general purpose equipment in the protected enclosure. Used as a Type Y purge reduces classification from Div. 1 to Div. 2. Type Z purge reduces classification from Div. 2 to Non-Hazardous. Purge/pressurization systems can be used for electronics, electrical equipment, motors and switch gear in wall-mount to large enclosures, and also meet the demands of rack-mounted instrumentation, video displays, programmable controllers, computers, printers, recorders and measurement and calibration equipment. Available for 90 cubic feet maximum enclosure volume in vertical mount (VM) or horizontal mount (HM) models.

The thermostat is usually connected directly and switched without the need for additional relays and offers high switching capacity with small hysteresis (switching difference). Hazardous Location Heater Designed for use in hazardous locations where electronic components require protection from condensation and corrosion, sudden temperature drops and low temperatures, Hoffman s Hazardous Location Heater offers maintenancefree, high-performance heating with a large convection surface, an extruded aluminum heat sink and VAC operation. Lock INSERTS (with key) Lock inserts are field-installable. Stainless steel material and different key locking systems provides maximum protection for your equipment. HAZARDOUS LOCATION BREATHER DRAINS Hazardous Location Breather Drains prevent moisture build-up within hazardous approved enclosures while maintaining enclosure UL Type rating. Drains are to be used when an enclosure is subject to fluctuations in temperature which can lead to the formation of condensation and a subsequent moisture build-up. These drains allow air within an enclosure to breathe with the surrounding atmosphere, preventing condensation and any potential damage to electrical equipment. HAZARDOUS LOCATION WINDOW KITS Hazardous Location Window Kits are designed to be used on Increased Safety (Ex e) enclosures in ATEX or IECEx Zone 1 or 2 hazardous areas. These window kits are made with a robust heavy-gauge Type 316 stainless steel frame and a silicone gasket to ensure a dust-, oil-, and water-tight seal. Designed for use as viewing windows, these window kits are ideal for visibility of internal enclosure components. The window are easily installed by making a cutout in the enclosure and attaching the window and frame with included mounting hardware. ZONEX ENCLOSURES 11
