Chapter 5 American/Actaris Commercial Meter Installation
• One extension driver
The old adapter plate will not work with the 100G ERT Module. However, the new adapter
plate will work with the old and new Itron ERTs.
To mount the index assembly to the adapter plate
1. Align the index assembly so that the back outside holes on the index mounting bracket
line up with the two smaller holes towards the center of the adapter plate.
2. Place and tighten the two bracket screws. When assembled, the index assembly should
look centered on the adapter plate.
3. Turn the 100G ERT Module upside down in your hand.
4. Use the other hand to place the four screw bushings into the 100G ERT Module's
screw holes. If the screw bushings become dislodged before final assembly, replace
them and repeat process.
5. Turn the 100G ERT Module right side up.
6. Place the extension driver onto the 100G ERT Module wriggler.
7. Turn the meter’s IDM outer drive dog so it is facing the same direction as the 100G
ERT Module wriggler.
8. Carefully place the 100G ERT Module onto the meter. Make sure the meter’s IDM
outer drive dog is still lined up with the 100G ERT Module wriggler. The INLET
label on the meter top must be beside the INLET label on the 100G ERT Module.
9. Gently place the adapter plate and index assembly onto the 100G ERT Module
attached to the meter.
