3.2.3 Seismic isolation
This section explains installing units using seismic isolation.
When a unit is installed using seismic isolation, the leveling feet of the unit must be
replaced with seismic-isolation leveling feet (CA80001-0064).
If openings for cables or air conditioning are provided on the free-access floor,
secure the following distances:
1 105 mm or more from the center of a seismic-isolation leveling foot
2 60 mm or more from the center of a caster
Figure 3.7 shows an example of opening on the free-access floor when a seismic-
isolation leveling foot is used.
