4 EFP Series Introduction The EFP Series of electrical connectors is a comprehensive line of power, control and instrumentation electrical connectors products. This series is certified for use in Zone 1 and Zone 2 classified locations with IP68 environmental sealing characteristics. EFP Series electrical connectors may be specified for use in Oil, Gas and Petro- Chemical applications, land based and offshore drilling systems and pharmaceutical grade applications. Areas of application include power, control and instrumentation circuits requiring quick and safe connection and disconnection in service. This series is also readily available, with an extensive inventory to support small or large requirements. The EFP Series of connectors are designed for use with both single and multi condutor cable types and are designed for service in the most demanding environments. The connector bodies are manufactured from hard anodised aluminium, alternative materials such as brass and stainless steel, nickel aluminium bronze and titanium are also available. EFP series connectors are designed for quick mating and unmating in service. Cable accommodations including armored and sheathed allow industrial, offshore, and petrochemical type cables to be terminated in various manners depending on cable type as well as application and regulatory requirements. Receptacles are available for panel or cable 'inline' mounting. Receptacles with a potting adaptor can be installed into either an EEx 'd' flameproof, EEx 'e' increased safety or EEx 'p' purged type enclosure systems. The contact termination methods available are solder, crimp or pressure termination depending on insert selection. Contact materials are copper alloys and various plating options are available depending on application and ampacity. Silver and gold plating, over copper contacts are standard. The EFP series lends itself to both single and multi conductor applications, with a comprehensive range of inserts to suit wire size 18 AWG(0.75mm 2 ) to 1111 MCM(563mm 2 ). Multipole power inserts are available up to 600 amperes at 1000V, Single pole power to1135 amperes at 1000V. Control and instrumentation inserts are available in 2 through 143 contacts. Composite inserts (power & control) are also readily available. For planned non intermateability connectors maybe furnished with alternate key positions andmay be color coded.

5 ATEX Directive Overview The EFP Connector series is certified in compliance with the ATEX Directive, European Community Directive 94/09/EC (see pages 28 and 29 for a more thorough explanation of ATEX directives). To ensure operator and equipment safety this directive covers a wide field of safety requirements including:» Integrated safely requirements» Specific conditions of inspection and maintenance» Environmental conditions» Marking» Instructions for use» Choice of materials» Design and manufacture» Potential ignition sources such as sparking, electric arcs, high surface temperatures» Explosive atmospheres caused by the presence of gas, vapours and mist» Explosive atmospheres caused by the presence of air-dust mixtures. The approval was issued by Intertek ETL SEMKO. ITS08ATEX15916X The connection system has a "component acceptance" approval number which simplifies the certification procedure of equipment to which the EFP Series can be fitted to. This means that the connector is accepted as being suitable for use on other certified Fameproof equipment. It will not be necessary to submit documentation or connector samples for repeat examination and testing when it is incorporated into new flameproof equipment designs. EEC is committed to developing the EFP series in accordance with the ATEX directive and regulatory requirements.

9 Ex Connectors Application and Features Temporary but safe connecting and disconnecting of power is critical in many industries. In order to maintain this safety requirement, Elecquip has introduced a new series of EExd Connectors that are ATEX approved, easy to use and exceptionally robust. They allow for safe and rapid service, repair and replacement of key plant, or provide quick connection to temporary equipment. Their application is beneficial in high-productivity environments where minimum interruption of service is essential. The connectors are ideal for Zone 1 and Zone 2 explosive environments commonly found in oil and gas exploration, production and process plants. However, their features also offer benefits in Zone 21 and Zone 22 explosive dust environments, or in harsh and hostile non-explosive applications. In compliance with the ATEX Directive (94/9/EC), the design retains many of the features of Elecquip's already high-quality connectors, but in addition adding innovations based on your user feedback. The heavy-duty, maintenance free stainless-steel body construction is retained, along with the acclaimed Acme mating thread: enabling quick connection whilst preventing thread binding or galling. Faster Assembly An internal sleeve provides an extended installation key way which assists connector assembly by making insertion easier and quicker, and also helps to prevent insert misalignment and potential contact damage. Impossible to Cross-mate The unique visual 5 position keying system (3 on EX16) prevents contact damage and ensures safe use by eliminating the possibility of misconnection of adjacent circuits. Fully Inspectable Flameproof Barrier The removable compound chamber technology allows direct access for visual inspection of the flameproof barrier seal and offers users the peace of mind that the connector is safe for installation into flameproof and increased safety equipment. High Reliability Contacts Each Pin and Socket is fitted with Multilam Band technology to ensure reliable low resistance connection on each coupling. Quick and Easy Fieldwiring The Pin and Socket inserts are numbered from and back to assist wiring and avoid potential termination errors. EFP Flameproof Connector Series Page 7

26 Technical Data The intent of this section of the catalogue is to identify important features that may be useful in the selection and installation of explosion protected electrical equipment. There are numerous different regulations, codes, guidelines and standards for the design, installation and maintenance of electrical and non-electrical systems for use in potentially explosive atmospheres. The type of operational facility, geographic location, operator practice, local and national legislation, authority having jurisdiction etc. will determine many of the design and installation rules permitted. A fixed or floating petroleum facility located offshore, for example, would not be designed or classified in the same manner as an onshore petrochemical facility. Potentially Explosive Atmospheres An explosive atmosphere is defined as a mixture: - Of flammable substances in the form of gases, vapors, mists, dusts or fibers - With air - Under atmospheric conditions - In which, after ignition has occurred, combustion spreads to the entire unburned mixture Area Classification (Classification of Locations) The purpose of the are classification is to provide a basis for the correct selection, installation and location of electrical and non-electrical equipment in those areas. Areas must be classified depending on the properties of the flammable vapors, liquids, gases, mists, combustible dusts or fibers that may be present and the likelihood that a flammable or combustible concentration or quantity is present. The aim of area classification is to avoid ignition of flammable releases that may occur in the operation of facilities. The intent is to reduce to an acceptable minimum level the probability of a flammable atmosphere and an ignition source occurring at the same time. CENELEC and IEC Area Classification Area classification is the division of a facility into three-dimensional hazardous areas and nonhazardous areas and the sub-division of the hazardous area into Zones. Hazardous areas may be sub-divided into three Zones as follows: Flammable Gases and Vapors Zone 0 Zone 1 Zone 2 An area in which an explosive atmosphere is constantly present, or present for long periods An area in which an explosive atmosphere is likely to occur in normal operation (about 10 hours or more per year but less than 1,000 hours per year) An area in which an explosive atmosphere is not likely to occur in normal operation and if it occurs, it will exist only for a short time (about less than 10 hours per year) Page 24 Elecquip

27 Combustible Dusts Zone 20 Zone 21 Zone 22 An area in which combustible dust, as a cloud, is present continuously or frequently during normal operation, in sufficient quantity to be capable of producing an explosive concentration of combustible dust in a mixture with air An area, in which combustible dust, as a cloud, is occasionally present during normal operation in a sufficient quantity to be capable of producing an explosive concentration of combustible dust in a mixture with air An area, in which combustible dust, as a cloud, may occur infrequently and persist for only a short period, or in which accumulations of layers of combustible dust may give rise to an explosive concentration of combustible dust in mixture with air For further information on the classification of hazardous areas, see: IEC Electrical Apparatus for Explosive Gas Atmospheres, Classification of Hazardous Areas IEC Electrical apparatus for use in the presence of combustible dust Part 3: Classification of areas where combustible dusts are, or may be, present IEC Electrical Apparatus for Explosive Gas Atmospheres, Classification PR EN Classification of areas where dusts are, or may be, present Institute of Petroleum - Model Code of Safe Practice in the Petroleum Industry, Part 15: Area Classification Code for Petroleum Installations, IP 15 Classification Society A Classification Society may also enforce requirements for the design and installation of facilities. These requirements, which are in addition to statutory requirements, may influence the design and installation of electrical systems. Classification Societies include ABS, DNV and Lloyds Register. Design and Installations of Electrical Systems for Hazardous (Classified) Areas There are numerous regulation codes, guidelines and standards for the design, selection and installation of electrical installation in potentially explosive atmospheres. These requirements are in addition to the requirements are in addition to the requirements for installations in nonhazardous areas. There are several types of protection, i.e. construction techniques, available for electrical apparatus in hazardous areas. The type of protection permitted will depend upon the applicable installation codes and rules to be adopted. The selection of electrical apparatus should be in accordance with the following: - Classification of the hazardous area - Temperature class or ignition temperature of the gas, liquid, vapors, mist, dust or fiber - Where applicable, the gas, vapor or dust classification in relation to the group or subgroup of the electrical apparatus - External influences and ambient temperatures EFP Flame Proof Connector Series Page 25

32 Gland and Enclosure Technical Data The protection of the enclosure and the equipment inside against external influences of conditions, such as: mechanical impacts, corrosion, corrosive solvents, solar radiation, icing moisture (e.g. produced by condensation), and explosive atmospheres, are matters that should be dealt with by the relevant product Standard. There are additional and supplementary optional letters to the above coding; these designations are A, B, C and D and H, M, S and W, and further information can be found in the relevant Standard(s). Deluge Ingress Protection (per DTSd) On offshore facilities, equipment may be located in areas subject to emergency deluge systems. Equipment that has been evaluated as certified for use in hazardous areas may not be suitable for use in these locations. A testing method for electrical equipment to be installed in areas subject to deluge systems, DTS01, has been prepared by the Explosion and Fire Hazards Group of ERA Technology (now know as ITS) in collaboration with Shell UK Exploration and Production Ltd. Testing includes: - Energizing the equipment (where appropriate) for 60 minutes prior to the deluge test, then interrupting the electrical power at the start of the deluge test and resuming after 60 minutes until the completion of the deluge test. - Carrying out insulation resistance testing before and after pre-conditioning and after the deluge test, where applicable. - Carrying out pre-conditioning by exposure to vibration and thermal ageing at 90% relative humidity and at a temperature 20k above the equipments maximum service temperature and/or at least 80 C of any appropriate seals. - Carrying out deluge test using a deluge chamber fitted with deluge nozzles that apply a salt water solution deluge pressure within the range of 3.5 bar to 4.5 bar at a water temperature in the range of 5C to 10C for 3-hours. IECEx Scheme The objective of the IECEx Scheme is to facilitate international trade in electrical equipment intended for use in potentially explosive atmospheres by eliminating the need for multiple national certification. The IECEx Scheme provides a means for manufacturers to obtain Certificates of Conformity may be obtained from any certification body accepted into the scheme. The objective of the IECEx Scheme is world-wide acceptance of one standard, one certificate, and one mark. For the IEC Scheme to achieve its objective, every applicable national standard will need to be identical to the corresponding IEC standard. A transition period will be necessary to allow time for participating IECEx Scheme countries to align their national standards with the IEC standards and work towards national acceptance of IECEx Certificates of conformity and the IECEx mark. North American Hazardous (Classified) Locations Area Classification Area classification is the division of a facility into a two or three-dimensional hazardous location, a non-hazardous location and the sub-division of the hazardous location into Divisions or Zones.

39 CE Marking Introduction CE Marking The CE Marking is intended to facilitate the free movement of products within the European Union. By affixing CE marking to products, the manufacturer is making a legal declaration that the product meets with the appropriate requirements of all relevant European Directives. CE marking only applies to products within the scope of the Directives. It should not be applied to products if they are outside the EMC Electromagnetic Compatibility Directive Most electrical and electronic products made or sold in the EU must: - Be constructed so they do no cause excessive electromagnetic interference and are not unduly affected by electromagnetic interference - In the case of certain radio-transmitting equipment, be subject to EC type examination by a notified body - Carry CE marking Cable glands are not considered to come within the scope of the Directive, however we have carried out independent third-party testing on the EMC shielding effectiveness of our armored type cable glands fitted into single wire armored and braided-type cables. The electromagnetic ingress between the cable sample (perfect connection) and that of the cable sample fitted with the cable gland was of such a small magnitude that it could be regarded as within acceptable uncertainty of measurement. As such, it can be concluded that the shielding effectiveness of single wire armored or braided cable is maintained when fitted with an appropriate Hawke armored type cable gland. Low Voltage Directive The Low voltage Directive 73/23/EEC embodies a number of principles: - Only electrical equipment that does not jeopardize the safety of people, domestic animals and property, is permitted on the market - Only electrical equipment, that satisfies the CE marking requirements of the LVD, is in compliance - Electrical equipment is not required to be tested or marked for approval by an independent third party - Enforcement is the responsibility of each member state within its national jurisdiction - The regulations apply to all electrical equipment, except where extensions apply, that is designed for use between 50 and 1000 volts ac or 75 and 1500 volts dc - Only components, which are in themselves electrical equipment need satisfy the Low Voltage Directive Cable glands are not in themselves electrical equipment and therefore do not fall within the scope of the LVD. Certification / Listing / Approvals Electrical equipment for use in potentially explosive atmospheres is usually certified, listed or approved by a recognized Certification Body or Test House. In Europe, there are numerous Certification Bodies such as BASEEFA 2001 Limited and SIRA in the UK. In North America, there are many recognized Certification Bodies and testing laboratories such as UL, FM and the CSA. The definition of Approved by the NEC is Acceptable to the authority having jurisdiction. The definition Listed by the NEC is Equipment, materials or services included in a list published by an organization that is acceptable to the authority having jurisdiction. Further information is given in the NEC. EFP Flame Proof Connector Series Page 37

40 CE Marking and the 94/9/EC Atex directive Mandatory within the European Union CE Marking and the 94/9/EC Atex directive on equipment and protective systems intended for use in potentially explosive atmospheres. 'CE' marking has been introduced as part of the European Union's new approach to technical harmonisation as a means of identifying products that comply with all relevant EC Directives. Subject to certain safeguards, products bearing the CE mark are permitted to be sold throughout the EU without interference from national regulatory authorities. The Directives have been put in place in order to remove artificial trade barriers within the European Union previously caused by individual countries' national standards, a secondary function is as a means of regulatory safety. The Explosive Atmospheres 94/9/EC ATEX (Equipment) Directive became mandatory on 1 July On this date, the existing Explosive Atmospheres and Gassy Mines Directives were repealed. Since then, only equipment and systems CE marked as compliant with the ATEX Equipment Directive (and all other relevant mandatory directives) may placed on the market within the EU. The Directive applies to all equipment and systems for use in potentially explosive atmospheres within the EU. The scope of the Directive includes electrical and mechanical equipment for use in Group I (mining) or Group II (industrial) applications, both on and offshore and considers risks of ignition of potentially explosive gas, vapour, mist and dust atmospheres. IN addition, devices intended for use outside potentially explosive atmospheres that contribute to the safe functioning of equipment and systems with regard to explosion risk are also included. Compliance of products to the ATEX Equipment Directive, through conformity assessment, takes a modular approach and is generally in two stages: design and production. A common route to product design compliance is to apply to a Notified Body (EX. Test House) for an EC Type Examination Certificate. To comply, the equipment or system must meet the Essential Health and Safety Requirements (EHSRs) listed in the Directive. Harmonised EU standards have been adopted by CENELEC and CEN, relating to the design, construction and testing of equipment; a product complying with these standards is deemed to meet the EHSRs to which the standards relate. Where apparatus follows a protection concept not covered by these standards, compliance to the 94/9/EC Directive is still possible by compiling a 'Technical File' from first principles, demonstrating compliance through test and assessment to the EHSRs relating to design and construction of equipment for use in explosive atmospheres. The production quality stage of the conformity assessment procedures ensure continued product compliance in manufacturing. Typically a manufacturer should have a certified ISO 9000 quality management system and comply with one of the quality modules in ATEX Equipment Directive, however this will vary depending on product equipment category; equipment used in higher risk areas will require more onerous conformity assessment procedures to be applied. In addition to the 94/9/EC ATEX (Equipment) Directive, products for use in potentially explosive atmospheres may require to be compliant with other Directives including the 89/336/ EEC Electro-magnetic Compatibility (EMC) Directive, which became mandatory on 1/1/96. This Directive applies to virtually all electrical and electronic apparati potentially able to generate interfering emissions or exhibit an undue sensitivity to interference sources.

41 99/92/EC ATEX directive Workers' Safety Once compliance with the relevant Directives is complete and en EC Declaration of Conformity issues by the manufacturer, the 'CE' mark may be applied and the product placed on the market. The ATEX Equipment Directive in full, and EC Commission guidance on the Directive, may be found on the following website: 99/92/EC ATEX (Workplace) Directive on minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres. Workplaces in operation before July 2003 must comply by July 2006 Workplaces coming into use after July 2003 must comply immediately The Directive covers both Group I and Group II activities, on shore and offshore with the EU, and aims to provide a better level of protection for the health and safety of workers in potentially explosive gas, vapour, mist and dust atmospheres. It lists a set of obligations and safety measures for employers, requiring the adoption of a coherent risk assessment based strategy for the prevention of explosions. These obligations include: likelihood of the presence of the explosive atmosphere, the presence of ignition sources (including electrostatic discharge), identification of the substances and processes in use, definition of specific measures taken to safeguard the health and safety of workers use of written instruction and permits to work - Equipment in service before 30 June 2003 may be used after this date if it has been risk assessed and the explosion protection document indicates it can be safely used - Equipment bought into service after 30 June 2003 must be CE marked as compliant with the 94/9/EC ATEX (Equipment) Directive - Control of releases - Use of protective measures appropriate to the greatest potential risk - Selection of proper equipment by referencing the explosion protection document - Ensuring equipment is correctly maintained and operated - Minimizing the risk of explosion and the effect of explosion in the workplace 99/92/EC is a separate directive specifically covering workers in explosive atmospheres, working within the more general 89/391/EEC Directive on the introduction of measures to encourage improvement in the safety and health of workers at work. The ATEX Workplace Directive in full may be found on the following website: DSEAR - The Dangerous Substances and Explosive Atmospheres Regulations 2002 In the UK, the 99/92/EC ATEX workplace Directive will be implemented as The Dangerous Substances and Explosive Atmospheres Regulation 2002 (DSEAR). These regulations will also include the safety aspects of the 98/24/EC Chemical Agents directive, resulting in flammable and dangerous substances being covered by a single set of regulations, thus reducing the volume of legislation covering this area.

43 Ex Connector Selection Power and Control: Wattage Dissipation Calculation To select the shell size of the connector, it is essential that you calculate the dissipated wattage of the arrangement. This ensures that the arrangement does not exceed the maximum permitted temperature classification with regard to the upper ambient temperature for the area of installation. Refer to Table 1 for the maximum allowable dissipated wattage per connector size and use the calculations below to determine safe and proper working environment around electrical contacts. Table 1 Table 2 Contact Size Ex16 Ex25 Ex32 Ex40 Ex50 Upper Ambient Temperature of +40 o C Temperature Class T6 5W 8W 10.5W 12W 13W T5 7W 11W 14.5W 17W 20W Equation Definitions Upper Ambient Temperature of +50 o C Temperature Class T6 4W 6W 8W 9W 10W W = Dissipated wattage factor of the connector Upper Ambient Temperature of +65 o C Temperature Class N = The number of conductors to be terminated/number of contacts required (NOTE: A contact comprises of a pin and socket) I = The current requirements per contact (NOTE: This must be equal to or less than the maximum current rating of the contact, as shown in table 2) T5 T6 Maximum Allowable Dissapated Wattage Dissipated Wattage Calculation 6W 10W 12W 14W 17W 2W 3W 4W 4W 5W T5 4W 6W 8W 9W 10W Contact Size (mm 2 ) /0 4/0 262MCM 313MCM 350MCM 373MCM 500MCM 535MCM 646MCM 777MCM 1111MCM Contact Resistance (MV) Soldered Crimped ATEX Current Rating (amps) R = The contact resistance (see table 2) Values relevant to these definitions must then be input into the following equation to calculate the dissipated wattage (W) of your chosen arrangement: W = N x I 2 x R NOTE: The results must be lower than the maximum figure shown in table 1 for the appropriate temperature class and ambient temperature Example: T6 40C ambient application with 4 x 1.5mm 2 conductors, each running at 9 amps N = 9 I = 9 amps R =.0055 (1.5mm 2 contact resistance) W = 9 x 81 x.0055 = 4.01 watts An Ex25 Connector should be specified for this application as the shell size can accommodate the required 9 x 1.5mm 2 pin/socket inserts and the resultant dissipated wattage (4.01 watts) is below the maximum permitted 8 watts (see table 1). This equation can also be transposed to facilitate the calculation of the maximum number of conductors permitted in your selected connector (equation 1 below) and the maximum allowable current with the upper ambient temperature of your location (equation 2 below) W N = I = R x I 2 Equation 1 Equation 2 W N x R NOTE: The result of equation 2 must not exceed the maximum current rating of the contacts (see table 2) NOTE: Unless otherwise requested, connectors will be marked as T5 with an upper ambient temperature of +40 o C EFP Flame Proof Connector Series Page 41
