Inspect the Pulser Cable • Inspect the end of the pulser cable that will connect to the IMU. – There should be three wires exiting the outside insulation. – The red and black wires are insulated. – The 3rd wire is bare coming out of outside insulation, with a white sleeve on the end. • If needed, trim the pulser wires so the conductor is flush with the insulation and sleeve. Insert photo Pulser installation onto the gas meter is not covered here. Refer to the pulser manufacturer’s installation instructions. © 2010 Silver Spring Networks | Company Confidential 9

Inspect the IMU • Verify that the IMU has 3 wires • Verify that the enclosure is not • Verify that the cracked and that the MAC Address battery label is present connectors are undamaged. • Verify If the IMU is damaged, return it to your supervisor and get a replacement. © 2010 Silver Spring Networks | Company Confidential 10

Connect the Pulser to the IMU •Thread the pulser cable through the cable seal connector. •Thread the pulser cable through the tie wrap. •Connect the 3 cables with the gel splices. – Do not strip the insulation from the wires. – Insert the wire pair (red and red, black and black, white and white) to be connected into a gel splice; push all the way forward. – Close the gel splice by squeezing the gel splice with pliers. – Repeat for the 3 pairs of wires © 2010 Silver Spring Networks | Company Confidential 11

Connect the Pulser to the IMU • Make sure the 3 gel splices are to the right of the cable tie. • Tighten the cable tie. This provides extra strain relief for the cable. • Trim the cable tie. • Leave 1” of cable slack inside the IMU, and pull the rest of the cable out of the cable seal connector. • Tighten the cable seal connector. © 2010 Silver Spring Networks | Company Confidential 12

Connect the Battery Cable Connector •Connect the battery cable to the IMU cable. The connectors are keyed; you will not need to force them together. •Put the battery inside the battery compartment as shown. – The connector fits underneath the battery. – The flat part of the battery should be next to the inside wall. © 2010 Silver Spring Networks | Company Confidential 13

Program the IMU for Field Use • Slowly pass the service magnet once (for 2 to 5 seconds) over the top of the IMU. • Watch for the light-emitting diode (LED) to flash on the lower left corner of the IMU circuit board – If you don’t see the LED flash, make sure the battery cable connections are made. – If you still don’t see the LED flash after checking that all the battery connections are made and re- swiping the magnet, return the IMU to your supervisor.
