7.Pull out any slack from the OIT operating cable.

8.Rotate the rear of the OIT enclosure back into position while gently pulling out the new slack generated in the cable as you proceed.

CAUTION: Due to the large size of the ferrite coil, it must be positioned very carefully. Make sure that when the OIT enclosure halves are brought together, the ferrite coil is positioned so there is no internal interference. The ferrite coil must be positioned up against the inside wall of the OIT enclosure with the protruding OIT operating cable kept short.

9.Tighten the cable strain relief nut.

10.Re-install the four screws into the back of the OIT enclosure
