Installation and Commissioning
6. Press the extender module down and push in the lower part until you hear it
click into place in the 35 mm standard rail.
7. Push the extender module slowly to the left while keeping it straight and with-
out skewing and check that the two guide bolts on the extender fit into the
holes in the basic device. Then push the extender module to the left as far as it
will go so that it is flush with the right side of the basic device.
8. 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.
9. Fit the CV490 4x100 cover to slot 11 of the basic device and slots 12 and 13 of
the twisted pair extender.
