1 TECHNICAL BULLETIN 1(2) TB1212 August 01, 2012 TOPIC: CONCERNS: MORLEY EMW 32 S 132 KW HYDRAULIC PUMP MOTOR GLAND ADAPTER PLATE CERTIFICATION This technical bulletin is applicable to Sandvik Bolter Miners fitted with Morley EMW 32 S 132 kw hydraulic pump motor certified under IECEx TSA X. Motors certified to AUS Ex 3364X are not affected. Our records indicate at least the following machines have been identified as potentially having a Morley EMW 32 S 132 kw hydraulic pump motor. Sandvik MB650 Bolter Miners Serial 161, 164, 174, 176, Numbers 204 Sandvik ABM25 Bolter Miners Serial 19, 26, 27, 37 Numbers Sandvik MB670 Bolter Miners Serial 135, 137, 144, 190 Numbers The Owner of machinery has a liability to inform and when necessary to train according to the content of this Bulletin all the personnel (like operators, maintenance personnel) whom this Bulletin concerns. BULLETIN NUMBER: TB1212 Purpose To notify the owners and operators of Sandvik Bolter Miners in Queensland that it has come to our attention that the gland adapter plate on the Morley EMW 32 S 132 kw motor is not certified under IECEx TSA X. Description This motor forms part of a series of motors that were originally certified by SIRA (UK) under certificate of conformity IECEx SIR X. The gland adapter plate certification drawing , copy attached, was included in Issue 3 of this certificate, copy attached refer drawing list on p4 of issue 3. They were subsequently recertified by TestSafe under certificate of conformity IECEx TSA X, to enable use in Queensland. However the gland adapter plate was not included under IECEx TSA X. Hence all motors with this gland adapter fitted are not certified for use in ERZ1 zones in Queensland. IECEx TSA X lists drawing Rev. D on the drawing list of Issue 2. This drawing refers to drawing , which shows the terminal box gland entry point and adapter plate mounting face used on the motors supplied by Sandvik. The gland adapter plate drawing is not called up on this drawing SANDVIK MINING AND CONSTRUCTION AUSTRALIA PTY LTD 431 Masonite Road ABN: Heatherbrae NSW 2324, AUSTRALIA Issued Bulletins are available on the Sandvik website at: This document shall be incorporated in the "information of use" documentation and kept there for the life of the product. Unless otherwise specified, Sandvik accepts no responsibility for changes, labor or replacements incurred from this bulletin.

2 TECHNICAL BULLETIN 2(2) TB1212 August 01, 2012 Sandvik and Morley plan to resolve this issue as soon as possible. This involves: 1. Morley submitting an application to TestSafe for this gland plate to be included in certificate of conformity IECEx TSA X. This will be done Wednesday 1st August. 2. We anticipate that TestSafe will undertake a desk audit of the drawings, test reports and SIRA certificates of conformity. They will advise if any changes are required, although this is not expected given that the adapter plate configuration has already been assessed and certified. 3. TestSafe will release Issue 4 of IECEx TSA X. Whilst we will endeavour to release this as soon as possible, the present estimate for release is end-august, early September. 4. Sandvik will release a Technical Bulletin containing Issue 4 and associated drawings, Recommendations 1. The owner and/or operator of a Sandvik Bolter Miner inspect the equipment to unequivocally ascertain if a Morley EMW 32 S 132 kw hydraulic pump motor certified under IECEx TSA X is fitted. 2. Where this motor is fitted, review the attached documentation, and undertake a risk assessment to ascertain the continued interim use of the miner until a new issue of the certificate of conformity is released. Contact Contact your Sandvik representative for further information or any questions you may have. Approved by: Product Line Manager Alan Bruce Appendixes: 1. IECEx SIR X Issues 1 to 4 inclusive 2.

21 Page 3 of 5 Certificate No.: IECEx SIR X Date of Issue: Issue No.: 2 Page 3 of 5 Schedule EQUIPMENT: Equipment and systems covered by this certificate are as follows: The Type EM*** induction motor comprises a fabricated mild steel housing with bolt-on endshields and houses stator and rotor assemblies. The rotor shaft passes through the endshields by means of roller element bearings mounted in shaft gland arrangements. The machine is air cooled by means of a suitably guarded fan mounted on the non-drive end drawing air over the housing which is finned to increase the cooling area. The motor is provided with facilities for foot mounting. A fabricated steel terminal box, with a bolt-on access cover, is bolted to a mounting flange on the housing. Cables pass through the motor wall via a duct welded to the motor housing. A mounting flange is provided on the motor frame wall for the fitting of a bolt-on, cast iron terminal box (drawing ). A terminal plate is interposed between the box and the motor mounting flange with power and auxiliary moulded terminals passing through it and cemented in place. A facing is provided for the fitting of suitably certified and dimensioned cable entry components, with or without the interposition of a suitable adaptor. The machine has two poles and is rated for supplies up to V, 50/60 Hz; the type designation and rated output are proportional to the core length: Core Length Type designation Maximum Rated output 210 mm (minimum length) EM21 45 kw 780 mm (maximum length) EM kw CONDITIONS OF CERTIFICATION: YES as shown below: 1. When anti-condensation heaters are fitted they must be interlocked with the motor supply such that the heaters are only energised when the motor is de-energised. 2. When fitted with a shaft locking device, the motors must be fully disengaged before energising the machine. 3. Each terminal box fitted in accordance with this variation shall be subjected to a routine overpressure test at 9 bar, in all cases the pressure shall be maintained for at least 10 s as required by clause 16 of IEC :2001. There shall be no leakage, permanent deformation or damage. 4. Each Water way fitted in accordance with this variation shall be subjected to the following routine pressure of 51.8 bar for at least 30 minutes, there shall be no leakage, damage or permanent deformation as a result of the tests.
