Inspection (refer to 96-0072, Retrofit Meter Quality Acceptance Criteria) 3.1 Inspect the meter and cover for the following: - Meter and cover cleanliness, and no moisture inside the meter base - Unacceptable base damage - Lightning arrestors are in place and undamaged - Filters are in place - Cover seal (gasket) is in place - Insure that the meter is not unidirectional -Verify that the hi-pot barrier is in position 3.2 Verify that the AEP code on the label matches the meter type: 3.3 Module Inspection: Make sure the green PCB board is securely screwed into the BAMM/BAMMCCSK enclosure. There should be no visible gap between the top edge of the PCB and the top edge of the plastic enclosure. Note: Place ESD wrist-straps on prior to module disassembly procedure. 4. Module Disassembly 4.1 Carefully remove glass cover from meter. 4.2 Remove screws from module using a Philips #2 Screwdriver. Always use a manual screwdriver when unscrewing the module from the meter in order to prevent debris from falling into the meter. 4.3 Carefully place module facedown on the ESD mat on the workbench after disassembly. Interrupter BAMM Figure 1 MPI: GE, 240v, Single Phase, Remanufacturing Process 97-xxxx, Rev:A Page 5 of 13 5 AC Cable Disconnection Note: Old modules (RTOMM) have a different set of cables from the new generation of modules (BAMM/BAMMCCSK). Both types of cables are NOT exchangeable. The RTOMM cables have different inline components on each of the two cables. One of two RTOMM cables has a fuse incorporated on the cable and the other cable has a resistor incorporated on it. The BAMM/BAMMCCSK have 2 identical cables WITHOUT in line components. 5.1 Disconnect AC cable from the module. Use needle nose pliers to disconnect power leads from module. Gently grip on red AC cable tabs with needle nose pliers and disconnect the power leads. Pay close attention not to touch PCB with pliers and not to bend connection tabs on the board. Do not rotate tabs when disconnecting power leads. (Refer to Figure 2) Figure 2: Power Cable Orientation Resistor cable connector RTOMM Component Side Fuse cable connector 5.2 Disconnect AC cables from Current Coil. Use needlenose pliers to disconnect power leads from current coil. Grip on the edge of the superclip and gently remove clip from current coils. Remove any debris resulting from disassembly of the superclip from the copper coil. 5.3 Disregard and discard old cables. 5.4 All disassembled modules must be placed in ESD bags for storage. MPI: GE, 240v, Single Phase, Remanufacturing Process 97-xxxx, Rev:A Page 6 of 13 6. Interrupter Disassembly 6.1 Use needle nose pliers to remove interrupter from disk shaft. Gently pull the interrupter from the disk shaft with the needle nose pliers. Pay close attention when removing the interrupter and make sure that minimal force is exerted on the shaft. The shaft is extremely sensitive to force and can easily be bent when subjected to pressure 6.2 Disregard & discard old interrupters. MPI: GE, 240v, Single Phase, Remanufacturing Process 97-xxxx, Rev:A Page 7 of 13 ASSEMBLY INSTRUCTIONS Important Regulatory Requirements/Statements This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This device must accept any interference received, including interference that may cause undesired operation. The BAMMCCSK module is factory installed and is inaccessible to the user. The module must be sent back to the factory for any retrofit or maintenance required. The antenna used for this transmitter must be installed to provide a separation distance of at least 20cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. The BAMMCCSK module is designed to transmit only using one loop antenna having omnidirectional gains of not more than 0 dBi. 7.1 Power Cable Installation Note: Make sure to use the correct AC cables. The 240V BAMM and BAMMCCSK use the black AC cables WITHOUT the in-line components. Refer to the addendum part of the MPI for the soldering procedure ond 120V GE Meters. 7.1.1 Using the wire installation tool grip the superclip along its ears, open the pliers and place the clip onto the current coil, near the end on a straight portion of the coil. When attaching the superclips to the current coil, install the clips as shown in the diagrams below, with the wire exiting the superclip towards you. Notes: 1. Never place a superclip over the insulated portion of a current coil. 2. Jaw opening on the clip installation tool must be set to predetermined dimension: a) for GE I70 S-I, jaw opening = 0.22 b) for GE I70 S-II, Jaw opening = 0.34 3. It is preferred to have all clip prongs engaged with the current coil. On some meters, due to size of current coil and clip, the upper prongs do not become engaged. Acceptance criteria for clip engagement is: Clip must not slip on current coil by pulling (slight tug) on the wire. MPI: GE, 240v, Single Phase, Remanufacturing Process 97-xxxx, Rev:A Page 8 of 13 4. Do not attempt to re-use the wire. Reject the wire. Superclip placement on the current coil Spring clip Current Coil BAMM/BAMMCCSK AC Cable Assy. BAMM CCSK/ BAMM AC Cables (2X) BAMM MPI: GE, 240v, Single Phase, Remanufacturing Process 97-xxxx, Rev:A Page 9 of 13 7.1.2 Use the needlenose pliers to grip the AC cable fast-on connector, then press it fully onto the fast-on tab on the BAMM/BAMMCCSK. Repeat for the other cable. Note: Do not attempt to straighten a BAMM/BAMMCCSK fast-on tab that is bent. If the fast-on connector cannot be fully seated onto the tab because the tab is bent too much, reject the BAMM/BAMMCCSK. 8. Interrupter Installation 8.1 Insert the interrupter into the interrupter installation tool as shown below. It is important that the interrupter and the interrupter tool are properly oriented. Handle the interrupter from long side of hub not the interrupter blades. Do not touch the interrupter blades as you insert the interrupter into the tool. letter ‘G’ on this side long side of hub interrupter finger pressure meter disk Figure 3: Interrupter Installation 8.2 Carefully position the interrupter next to and parallel to the meter shaft with the spacer side 2of the tool resting totally flush on the bottom of the meter disk. Use your finger or thumb to press the tool totally flush against the disk when you snap the interrupter onto the disk. 8.3 Verify that the installation tool is held perfectly vertical, then gently squeeze the pliers until the interrupter snaps onto the meter shaft. If you don’t feel or hear the ‘snap’, the interrupter might be damaged or in the wrong position. MPI: GE, 240v, Single Phase, Remanufacturing Process 97-xxxx, Rev:A Page 10 of 13 8.4 Remove the interrupter tool from the meter base. Make certain that the interrupter blade is not twisted while removing the tool. Gently release the tool from the interrupter before removing the tool from the meter. 8.5 Using 0.025”feeler gage, check for interrupter blade- meter base clearance. The clearance should be checked for all blades and meter base on both sides of shaft. If clearance is less than feeler size(0.025”), the interrupter must be removed and a new interrupter installed. Repeat interrupter placement procedure. If the clearance is still less than 0,025place the meter aside and do not reuse meter. Acceptable versus unacceptable contact can be evaluate by inserting the feeler gage between the interrupter and the base without touching the disk or interrupter with anything else. If the interrupter and disk rotate even slightly when the feeler gage is inserted, there is unacceptable contact. Place the feeler gage closer to the end of the interrupter blades rather than closer to the disk shaft because the webbing of the interrupter could give a false failure reading. good location to place feeler gage. bad location to place feeler gage. meter passes meter OK, but fails test meter base Figure 4: Checking Proper Interrupter Instalation 9.0 BAMM/BAMMCCSK Installation 9.1 Take the new barcode label and attach it to the front face of the BAMM/BAMMCCSK. Make sure the label is square and does not interfere with any holes or writing on the enclosure. Verify the quality of the label print and the utility meter ID on the label matches the original label on the module. If there is a discrepancy between old and new label serial number, investigate the problem and print and attach the correct label. 9.2 Position the BAMM/BAMMCCSK onto the meter standoffs by rotating the BAMM/BAMMCCSK upwards and over the interrupter. Use the electric torque driver (set to 5 in-lbs) to secure the TOMM to the meter using two module mounting screws. Be very careful not to damage the screw heads. 9.3 Again rotate the disk gently to verify that there is no interference with the interrupter against the meter or BAMM/BAMMCCSK. MPI: GE, 240v, Single Phase, Remanufacturing Process 97-xxxx, Rev:A Page 11 of 13 9.4 Position the AC cables low around the perimeter of the meter base, but not into the BAMM/BAMMCCSK housing. Excess cable is folded over for both wires on the clip side. 9.5 Install the meter cover. Make sure the power cables are not pinched by the cover. Fold excess wires as shown. Fold over the excess wire as shown. MPI: GE, 240v, Single Phase, Remanufacturing Process 97-xxxx, Rev:A Page 12 of 13 Figure 5:Proper AC cable Installation and Routing 10.

Power Cable Installation Note: Make sure to use the correct AC cables with the 120V BAMM. The 120V BAMM uses the yellow AC cables without in-line components. 11.1 Soldering instructions for 120V meters only One of these two tabs will NOT have a meter wire installed. Use this one for the BAMM cable Meter wire Figure 7: 120v AC Cable Connection If surface of the eyelet/tab is dirty or corroded, use foam applicator and alcohol to clean the surface. Try not to generate any particles during this process, and be careful to remove any particles you do generate. Hook pre-tinned and formed wire through eyelet on meter tab and solder wire to tab. Visually inspect meter base for excess solder. Remove any excess solder with the solder braid and/or soldering iron. Note: No solder splatter or solder balls are permitted inside the meter. Clean the solder joint with alcohol to remove any residual flux. Give a slight tug on the wire to ensure the solder is securely attached to the tab. Note: Tab may remain hot for a few seconds. Wait 5-10 seconds before routing the cable near the tab. MPI: GE, 240v, Single Phase, Remanufacturing Process 97-xxxx, Rev:A Page 14 of 13
