Calculate primary rack clearance dimensions as follows (see
• Clearance "a" is the space between the service clearance at the left
side of the array (100 mm minimum for installing the kickplate) and
any other object, such as a desk or wall.
• Clearance "b" is the space between the service clearance at the right
side of the array (100 mm for the kickplate) and any other object.
• Clearance "c" is the space between the service clearance at the front of
the array and any other object.
• Use the value of "c" and your floor load rating to determine the values
for a and b according to the following steps.
1. Determine how much space you can assign to clearance "c". For
maintenance purposes, try to make "c" larger (1000 mm) rather than
smaller (0 cm). The smaller "c" is, the larger "a" and "b" must be.
2. In the floor loading table (Table 7
that most closely matches your value. If your "c" value is in 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.
3. 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 600 mm, then "a" can be 400 mm and "b"
can be 200, or both "a" and "b" can be 300.
