■ Measures against earthquakes
To have the rack system withstand earthquakes measuring more than 250 Gal, secure the system with
adequate earthquake-proofing measures. The earthquake-proofing measures include using leveling
feet and using the optional Quake Proof Stabilizer kit.
WARNING
Use bolts to secure the rack to the floor (slab).
Failure to use bolts to secure the rack to the floor (slab) may cause the rack to fall
over during any earthquake with a seismic intensity exceeding 250 Gal.
If the rack falls over, the result may be severe injury, death, and/or damage to the
devices in the rack and the surrounding area.

■ Securing the rack using the leveling feet
Install the rack so that it is anchored with the leveling feet that are provided on the bottom of the rack.
Adjust the leveling feet so that the rack is level.
Keep the casters 1 to 2 mm above the floor.
