Removing the Twisted Pair Extender from the 35 mm Standard Rail

To remove the device, you require a slotted screwdriver with a 2.8 mm wide blade.

The captive screw in the lower part of the extender module between slot 12 and 13 is not used for mounting on an 35 mm standard rail. When removing a twisted pair extender from a 35 mm standard rail, the basic device remains in position. Follow the steps below:

1.Remove the cover from slot 11 of the basic device.

2.Use a slotted screwdriver with a 2.8 mm wide blade to loosen the two captive slug screws on slot 11 of the basic device in the upper and lower recesses as far as they will go.

3.Push the extender module slowly to the right while keeping it straight until the two guide bolts of the extender module are completely outside the holes in the basic device.

4.Push the twisted pair extender down until the lower part can be pulled away from the standard rail to the front.

5.Lift the extender module up and off the 35 mm standard rail.

6.Replace the right side panel of the basic device so that the guide bolts fit into the two holes in the basic device.

7.Using a slotted screwdriver with a 2.8 mm wide blade, tighten the two captive slug screws on slot 11. The screws lock the two guide bolts, so do not use ex- cessive force when tightening them.

8.Fit a suitable cover on slot 11 of the basic device.

Note

The basic device must not be used permanently without the right side panel.
