positions in the frame with insert blocks [either cable insert blocks or blanking (solid) insert blocks (see figure 2Bl-l)]. (NOTE: Incoming cables may be installed on one end of the enclosure and outgoing

cables on the opposite end for large enclosures.  Where only one penetrator is used, incoming cables may be installed on one side of the wedgepack and outgoing cables on the opposite side.)

Step 8 - Tighten the nut on the wedgepack to compress the insert, until the outside wedge pack metal plate is almost flush with the bottom of the MCP frame blocks in the frame, using a wrench.  (NOTE: The wedge pack is fully tightened when the length of the pack is the same as the depth of the MCP frame.)  Continue to tighten the wedgepack nut until a torque between 5.7 and l6.9 N-m (50 and l50 in-lbs) is reached. After the blocks have been compressed for approximately 24 hours, retighten the nut to ensure that the seal is maintained.

Step 9 - Install terminations on the OFCCs as specified on the system drawings using Part 5 of this standard practice.
