M-192, Waluj MIDC, Aurangabad , Maharashtra State India (USA) Automation Instrumentation Inc Endress Place Greenwood, Indiana United States of America Yamanashi Co. Ltd , Sakaigawa-cho, Fuefuki-shi Yamanashi Japan GmbH+Co. KG This certificate is issued as verification that a sample(s), representative of production, was assessed and tested and found to comply with the IEC Standard list below and that the manufacturer's quality system, relating to the Ex products covered by this certificate, was assessed and found to comply with the IECEx Quality system requirements. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended. STANDARDS: The electrical apparatus and any acceptable variations to it specified in the schedule of this certificate and the identified documents, was found to comply with the following standards: IEC : Edition: 5 IEC : 2006 Edition: 5 IEC : 2006 Edition: 2 Explosive atmospheres - Part 0:Equipment - General requirements Explosive atmospheres - Part 11: Equipment protection by intrinsic safety "i" Explosive atmospheres - Part 26: Equipment with equipment protection level (EPL) Ga This Certificate does not indicate compliance with electrical safety and performance requirements other than those expressly included in the Standards listed above. TEST & ASSESSMENT REPORTS: A sample(s) of the equipment listed has successfully met the examination and test requirements as recorded in IECEx ATR: File Reference: DE/TUN/ExTR / DE/TUN/ExTR /

3 Page 3 of 4 Schedule EQUIPMENT: Equipment and systems covered by this certificate are as follows: The Fluid Level Switch Liquiphant M/S type FTL50 (H)/51 (H), FTL51C or FTL70/71 are used for the operation in potentially explosive atmospheres of combustible gases or fluids. The Fluid Level Switch directly detects the fluid level by means of a symmetrical vibrating fork and converts it into an electrical signal. Dependent on the applied electronic insert the output signal is a 4/20 ma current signal (electronic insert type FEL 55), a NAMUR signal (electronic insert type FEL 56/58), a pulse frequency modulated signal (electronic insert type FEL 57) or a fieldbus connection is possible (electronic insert type FEL 50A). Further the density elctronic insert FEL 50D for connection to FML621. For installation instructions, the category, the gas group and the temperature class, which applies to specific models as well as ambient and fluid temperature refer to safety instructions which are delivered by the manufacturer. Technical data see attachment "3rd supplement_iecex_tun_04_0017.pdf". CONDITIONS OF CERTIFICATION: NO

4 Page 4 of 4 DETAILS OF CERTIFICATE CHANGES (for issues 1 and above): The changes are as follows: Addition of stainless steel enclosure F27. It's the same shape as the enclosure F13 resp. F17. The Alu-enclosure F13 resp. F17 can be combined with cover glass window. The new material of process wetted parts is added (Hastelloy C22). The connection of the flex-jumper for FTL51C is changed. Further the electrical data of the electronical insert FEL50D are changed. The maximum values for the electronic insert are: U i = 27.6 V, I i = 93 ma, P i = 640 mw, L i = mh, C i = 2 nf The marking of the electrical apparatus is now: Ex ia IIC T6...T2 Ga/Gb. For the current technical data see attachment "3rd supplement_iecex_tun_04_0017.pdf". All other data apply for this issue. Annexe: 3rd supplement_iecex_tun_04_0017.pdf
