electronics configuration and communications, all the components related to the
electronics can now be physically removed from the meter. Unscrew all wiring from
the Field Termination Board. It may be helpful to label the wires to make it easier to
connect the 3410 Series electronics.
2. Remove any conduit and wiring attached to all six conduit ports.
3. Remove any ground wire attached to the ground lug on the outside of the upper
electronics housing. At this point there should be no wires connected to the upper
electronics housing.
