Gas IMU Installation and Configuration February 14, 2011 innovation in utility networking Overview • Remove existing index and prepare the meter • Attach the tamper magnet holder • Attach the index to the IMU • Attach the IMU assembly to the meter • Inspect • Prepare IMU for programming © 2010 Silver Spring Networks | Company Confidential Safety First! • Always follow applicable standards for safety! • Refer to the meter documentation for further safety information. • Follow your employer’s best practices. • If you smell gas, report it to the utility. • Do not use power tools! © 2010 Silver Spring Networks | Company Confidential RF Exposure Notice (509) • The antenna of this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. • The device should be installed so that people will not come within 20 cm (8 in.) of the antenna. • This equipment has been tested and found to comply with Part 15 of the FCC Rules. This equipment generates, uses and can radiate radio frequency energy, and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver disconnected. • Consult the dealer or an experienced Radio/TV technician for help. Modifications to the IMU not expressly approved by Silver Spring Networks may void your authority to operate the IMU. © 2010 Silver Spring Networks | Company Confidential Components and Tools • Components: • Tools: Component Qty.

Make minor placement corrections as needed. – The front gasket should adhere to the enclosure and keep the screw holes clear. – The rear gasket should be attached to the enclosure on the left and right, and remain straight in the middle such that the gasket will seal between the enclosure and meter. The gasket must keep the screw holes clear. © 2010 Silver Spring Networks | Company Confidential 11 Connect Battery Cable Connector • Gently plug in the battery cable connector to the PCB, if it is not already connected. – The connectors are keyed. The top side of the male connector has a feature that fits into a slot on the top side of the female connector on the PCB. – Orient the connectors before attempting to connect. – Carefully insert the male connector while holding the opposite end of the female connector. Do not push the male connector without holding the opposite end of the female connector. © 2010 Silver Spring Networks | Company Confidential 12 Attach the Meter Index to the IMU • Align the IMU drive train with the index wriggler. IMU Drive Train Index Wriggler © 2010 Silver Spring Networks | Company Confidential 13 Attach Meter Index to IMU • Use the two index screws to firmly attach the index to the IMU. • Index screw torque: – Rockwell: 6-7 inch pounds – American: 8-10 inch pounds • Rotate the drive shaft two turns from the rear, clockwise or counterclockwise, and observe that the 2 foot test hand also moves 2 turns. The test hand should spin freely. If not, correct by fixing or replacing the index or IMU. Two rotations of the IMU drive shaft will rotate the 2 ft drive hand two rotations. © 2010 Silver Spring Networks | Company Confidential 14 Attach IMU Assembly to Meter • Temporarily fasten the guide pins to the meter (3-4 threads into the meter). You will remove these in a later step. • Using the guide pins, align the IMU to the meter and match the meter wriggler to the IMU drive by adjusting the index test hand. – On the Rockwell meter, rotate the magnet to 12 o’clock to avoid the screw in the index well. – Watch (from the side or top) the IMU drive link to the meter wriggler. • On the American meter, the pin goes into the slot. • On the Rockwell meter, the cup fits over the wriggler (meter gear). © 2010 Silver Spring Networks | Company Confidential 15 Attach IMU Assembly to Meter • Hold the enclosure against the meter to maintain proper alignment to perform the following checks: – If no gas is flowing through the meter, verify that the half cubic ft test hand rotates approximately 180 degrees when turned gently by hand – If gas is flowing through the meter, you should see the test hands rotating. You do not need to manually rotate the test hand. • Verify that: – There are no clicking or snapping sounds – There is no gap between the meter and IMU Half foot test hand Two foot test hand – The rear gasket seals the meter to the IMU © 2010 Silver Spring Networks | Company Confidential 16 Attach IMU Assembly to Meter • If you hear clicking or snapping, or if there is a gap or a poor gasket seal, remove the IMU and reinstall. Repeat the verification checks. • Attach the index cover and 2 screws to the meter and IMU as shown. On a Rockwell meter, the curved side of the index cover goes on top. The red tamper plugs will fit to the upper left and lower right corners. • Tighten the 2 screws. Torque: – Rockwell: 6-8 inch pounds – American: 10-11 inch pounds © 2010 Silver Spring Networks | Company Confidential 17 Inspect Gaskets • Verify that the front and rear gaskets seal the mating surfaces all the way around the IMU and index cover. • If the gaskets have not seated correctly, remove all the cover screws, adjust the gasket position, and reinstall the IMU. © 2010 Silver Spring Networks | Company Confidential 18 Attach IMU Assembly to Meter • Remove the guide pins • Install the remaining 2 screws Install the remaining 2 screws and tighten Torque: – Rockwell: 6-8 inch pounds – American: 10-11 inch pounds © 2010 Silver Spring Networks | Company Confidential 19 Inspect the gaskets and install the tamper seals • Re-inspect the front and rear gaskets to ensure that they form a seal between the index cover, enclosure, and meter. • Use a nut driver to push the three tamper seals into the openings on the IMU (2 in the index cover and 1 in the battery door). © 2010 Silver Spring Networks | Company Confidential 20 Prepare the IMU for Programming • Slowly pass the service magnet once (for 2 to 5 seconds) over the top of the IMU. • Doing so wakes up the IMU, enabling you to program it. © 2010 Silver Spring Networks | Company Confidential 21 Rockwell 415 Gas IMU Installation and Configuration January 28, 2011 innovation in utility networking Rockwell 415 IMU Retrofit Overview • Check the components and tools list. • Remove the index cover and index. • Fasten the adapter plate to the meter. • Fasten the meter index to the IMU. • Fasten the IMU to the meter. • Fasten the index lens cover and the tamper seals. • Inspect • Prepare the IMU for programming. © 2010 Silver Spring Networks | Company Confidential 23 Check the Components and Tools List • Components: Component Qty.
