6.54 Inner Connection Points

For connection between the clusters (from bottom of top enclosure to the top of the bottom enclosure), both the front and rear rigging plates must be connected (see Figure 34). The maximum box-to-box angle is 45°.

When Rigging Box-to-Box, both front and rear tie plates must be connected.
