The total number of blocks required to construct the MDF is 100.

The construction of the MDF is based on the block counts made above and on the factors listed below.

Note that in some installations, such as this one, the arrangement of the frames may increase or decrease
the number of frames needed despite the block count.

●

Location of the MDF. The size of the equipment room governs the location of the MDF. For this
installation, the 25-ft-wide wall space is available close enough to the equipment to permit the use of
either wall-mounted or self-supporting frames.

Terminal-block mounting. For an installation of this size, the terminal blocks can only be mounted
on frames. Choose which of the two types of frames is to be used and whether the frames should be
wall mounted or self supporting.

— Wall-mounted frames. The  type-1 frame requires 10 frames and the type-2 frame requires 13

frames. This eliminates the type-2 frame since its 26-ft lineup would exceed the available wall
space of 25 ft.  The type-1 frame requires one additional frame to accommodate the required
spare blocks. Figure  5-1, 7-Module System Wall-Mounted on Type-1 Frame, shows one possible
arrangement.
