3.4 Installing the Rack
Basic requirement: Before installing the rack, be sure to adjust the leveling feet as described below,
regardless of whether the rack is to be anchored to the building floor. Keep the
rack level with the leveling feet. Be sure to position the casters 1 to 2 mm above
the floor. (Do not let the casters support the weight of the rack.)
3.4.1 Installation methods for the rack to withstand
earthquakes with an acceleration of up to
2.5 m/s
2
(250 gal)
In these methods, the rack can be anchored or not anchored. Use one of the following methods
depending on your situation.
1 Method where the rack is anchored to a stabilizing surface
Install the rack by using the same method described in "3.4.2 Installation methods for the
rack to withstand earthquakes with an acceleration of up to 10 m/s
2
(1000 gal)".
2 Method where the rack is not anchored to a stabilizing surface
Attach a stabilizer before installation.
Note: The attached stabilizer is a means of preventing the rack from tipping over during
device maintenance. If the rack is not anchored to a stabilizing surface, be sure to
attach a stabilizer before installation.
The stabilizer is an optional product (not supplied with this rack).
Stabilizers are attached to the rack as shown below. To select an appropriate stabilizer, take into
account the form of the rack with the stabilizer attached.
・Stabilizer (L-shaped): Attached to the front of the rack. This is equivalent to the stabilizers
supplied for conventional racks.
Note: A stabilizer for a conventional rack cannot be attached to this rack.
・ Stabilizer (pullout type): Attached to the bottom of the rack. You can put away the stabilizer body
underneath the rack.
