IMU Drive Train 2010 Silver Spring Networks | Company Confidential 11 Index Wriggler Attach Meter Index to IMU (cont.) Use the two index screws to firmly attach the index to the IMU. Torque:
Rockwell: 13-15 inch pounds American: 14-17 inch pounds Rotate the IMU drive train two turns, clockwise or counter-clockwise to ensure it spins freely. 2010 Silver Spring Networks | Company Confidential 12 Attach IMU Assembly to Meter Insert the four cover screws through the index cover and set the cover down. Attach the IMU assembly to the meter so that the drive train aligns with the meter wriggler and the screw holes on the meter align with those on the cover. 2010 Silver Spring Networks | Company Confidential 13 Attach IMU Assembly to Meter (cont.) While holding the enclosure against the meter to maintain proper alignment, rotate the test hand to verify proper engagement. Attach the index cover and screws to the meter. Torque:
Rockwell: 17-20 inch pounds American: 25-35 inch pounds Tighten the four screws firmly. Use the nut driver to push the two red tamper seals into place. 2010 Silver Spring Networks | Company Confidential 14 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 15 Rockwell 415 Gas IMU Installation and Configuration August 2010 innovation in utility networking Rockwell 415 IMU Retrofit Overview Check the components and tools list.
