Installing the 100G ERT Module

A gap at the screw locations is normal both before and after the index cover
mounting-plate screws are tightened.

7. Install the four ERT module mounting screws and tighten them, in a diagonal
sequence. Turn each screw 1/4 to 1/2 turn after it contacts the mounting plate. If you
are using a torque wrench, tighten to 72 inch-pounds.

8. Place new tamper seals over screws and press the seals into place with an 11/32 inch
nut driver, or other blunt tool.

To attach the index and cover

1. Locate the gasket previously removed and place it on the index cover mounting plate.

2. Align the gasket screw holes with the mounting plate's screw holes.

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.

8. Gently place the index assembly onto the adapter plate and install the two index
mounting screws.

9. Place the index cover over the index assembly. The transparent section of the cover
