Wall Mounting 66-Type Connecting Blocks
The first column of 66-type connecting blocks should be aligned with
the left side of the switch cabinet (Figure 3-7). This arrangement allows
for orderly growth toward the right side of the cross-connect field.
The connectorized 66-type connecting blocks are factory wired for
cable routing from the top so that the cable connector will align with the
connector on the connecting block. If cable routing from the bottom is
desired, then the connector on the connecting block must be removed
and rotated 180 degrees. Then, the connector must be relocated in the
previously unoccupied hole because the connecting block leads are not
long enough to reach the hole where the connector was previously
mounted. The VELCRO® cable retainer must also be relocated.
To install the cross-connect field, proceed as follows:
1. Draw a level horizontal line on the wall 12 inches above the floor
(Figure 3-17).
