If earthquake preparedness measures do not include securing the rack to the floor
In this method, the installed rack can withstand an acceleration force of up to 20
gal in a general-use building during an earthquake.
The stabilizer mounted to the rack is used to prevent the rack from toppling, such
as during maintenance of mounted units.
If earthquake preparedness measures include securing the rack to the floor
In this method, the installed rack can withstand an acceleration force of up to 1000
gal in a general-use building during an earthquake.
The rack is secured to the floor to prevent the rack from toppling, such as during
maintenance of mounted units.
2 Select the rack type.
To install the rack without taking earthquake preparedness measures: Select a rack
with the stabilizer -> Go to step 5.
To install the rack with earthquake preparedness measures taken: Select a rack
without the stabilizer -> Go to step 3.
Note:
Even if the building and floor where the rack will be installed are equipped
with functionality for earthquake preparedness, the rack requires a
mechanism for preventing it from toppling, such as during maintenance of
mounted units. Unless the rack will be secured to the floor, be sure to select
a rack with the stabilizer regardless of the building conditions.
3 If the rack will be secured to the floor, confirm the method of securing it.
If the earthquake proofing kit is used to secure the rack to the floor -> Go to step 4.
If the leveling feet are used to secure the rack to the floor -> Go to step 5.
Note 1: The only two methods that can be selected as the method of securing the rack
are using the leveling feet to secure it or using the earthquake proofing kit to
secure it. Select the appropriate method with consideration of the condition
at the installation site, such as with regards to the construction of the floor.
Note 2: No operation can be performed on a rack without the stabilizer until the rack
is secured to the floor. The rack must be secured to the floor to prevent it
from toppling, such as during maintenance of mounted units.
4 To use the earthquake proofing kit to secure the rack, an optional earthquake proofing kit
is required. The appropriate kits must be selected and prepared separately for basic racks
and expansion racks.
5 Issue a construction order for installation.
