2. In the floor clearance diagram:
a. Clearance “A” is the space between the service clearance at the left side of the array (10
cm minimum for installing the kickplate) and any other object, such as a desk or wall.
b. Clearance “B” is the space between the service clearance at the right side of the array (10
cm for the kickplate) and any other object.
c. Clearance “C” is the space between the service clearance at the front of the array and any
other object.
You use the value of C and your floor load rating to determine the values for A and B.
3. Determine how much space you can assign to clearance C. For maintenance purposes, try to
make C larger (100 cm) rather than smaller (0 cm). The smaller C is, the larger A and B must
be.
4. In the table after the diagram, find the column that most closely matches the size of C. If your C
value is between two table values, use the larger table value. Then, find the row for your floor
load rating. Where the column and row intersect is the A+B value.
5. To determine clearance A and clearance B, divide the A+B value between A and B. They do not
need to be equal. For example, if the A+B value from the table is 60 cm, then A can be 40 cm
and B can be 20, or both A and B can be 30. However, if your configuration includes only a
DKC, or a DKC and one DKU, then A must be at least 28 cm (11.1 in) to allow for opening the
DKC front door.
6. Calculate the floor clearance for the array using the following table.
