■ Measures against earthquakes
To have the rack system withstand earthquakes with an acceleration of more than 2.5 m/s
2
(250 gal),
fix it in place with adequate earthquake-proofing measures. The earthquake-proofing measures
include using leveling feet and using the optional Quake Proof Stabilizer kit.
・ Quake Proof Stabilizer kit
■ Securing the rack using the leveling feet
After the rack is transported to the installation site, 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.
’
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 an acceleration of more than 2.5 m/s
2
(250 gal).
If the rack falls over, the result may be severe injury and/or death. There may also be
damage to the devices in the rack and the surrounding area.
