6. Plug the supplied 18-pin jumper into the header on the back of the DSM3 Series circuit board.
8. Fasten the DSM3 Series to the Inverter Module by tightening the two captive screws. It
is recommended that the screws be tightened alternately, a few turns at a time so the
Communications Module aligns in parallel to the Inverter Module.
9. Reinstall the Inverter Module and reconnect the ribbon cable. Make front panel connections
(tamper, temperature sensor, battery sense, RF etc.).
10. If not yet done, record the cable modem MAC address from the front of the unit and report it to
the network manager for network provisioning.
7. Line up the 18-pin jumper with the header on the Inverter Module and gently push the DSM3
Series into the Inverter Module.
