3. Turn the index wriggler so it will go across the ERT module wriggler when you put
the index onto the mounting plate.
4. Carefully lower the index and cover onto the mounting plate. Place the index facing
the same direction it was before you removed it.
5. Align the index cover screw holes with the screw holes in the gasket and index cover
mounting plate.
6. Verify there is no gap between the bottom of the index cover and the top of the gasket.
If there is a gap, it may be the index wriggler is riding on top of the ERT module's
upper wriggler. To eliminate a gap, repeat steps 2, 3, and 4 until the cover fits
properly.
WARNING! Do not press down on the index cover if there is a gap. If
you do, you can damage the index wriggler or ERT module wriggler.
7. Turn each screw 1/4 to 1/2 turn after it contacts the cover.
8. Place new tamper or wire seals over or through the screw heads.
9. Press tamper seals into place with an 11/32 nut driver, or other blunt tool, or crimp the
seal if you are using wire seals.
100G ERT Module installation on the Sensus Commercial meter is complete.
