To help ensure business continuity
when earthquakes strikeSeismic isolation tables for earthquake protection.
Easily installed, they are your first line of defense
to ensure business continuity.
It is vital to take concrete step in business continuity,rather than shaping large-scale plans without implementing them.
THK seismic isolation devices are deployed in a wide array of settingsand situations to help protect vital devices.
To enable the rapid resumption of core operations in the aftermath of a destructive earthquake, a businessmust have measures in place to secure the necessary personnel, goods, financial resources, and information. In the quest for a comprehensive strategy, however, practical measures may be postponed or overlooked. The implementation of an effective practical measure—deploying easily installed Seismic Isolation
Tables to protect vital assets—is your best option: the crucial first step toward ensuring overall business
continuity.

Server computers

Antiquities and artworks

Seismic Isolation Tables Model TSD can be easily connected
and configured to accommodate a single server computer or
multiple servers, providing essential protection for vital datain the event of an earthquake.

The biggest threat to statuary and other artwork of historical value is the danger of toppling in an earthquake. The
use of Seismic Isolation Tables Model TSD is a highly
effective preventive measure.

Optical devices and other precision instruments
If an optical device or precision instrument is damaged, considerable time can be lost waiting for repairs
and resumption of service. Seismic Isolation Tables Model TSD are easily installed and offer highly effective
earthquake protection, essential for ensuring business continuity.

The Model TSD is easy to set up—simply place it on the floor.
No special construction is required. Tables are easily
connected and almost any configuration can be
expanded to handle a larger load.

During an earthquake, tables move throughout a range ofmaximum displacement (stroke). Sufficient clearance must be
provided wherever tables are situated, with no obstructions withinstroke range.

Trigger-A, Trigger-B
Both types unlock in response to seismic motion. Either type canbe attached to a table already in place (excluding the TSD-450).
• Trigger-A is designed for repeated use; at least two must beattached. Trigger-A is relocked manually after the table hascompleted its motion.
• Trigger-B, made of plastic, is designed for one-time use only. At
least four must be attached, all of which must be replaced withnew locks after the table has completed its motion.
Note: The optimal number of locks is determined by the weight of the load—please consult
THK for further details.

Seismic Isolation Table_TSD

THK offers four types of Seismic Isolation Tables Model TSD fora variety of applications. Additional modules can be added tothe TSD-1000 and TSD-1200 for expanded coverage,

Safety precautions

Warranty

Use of Seismic Isolation Tables• Please read the instruction manual carefully before using the Seismic IsolationTable.
• Do not dismantle or attempt to modify the Seismic Isolation Table. Any suchaction could cause the table to malfunction.
• Seismic Isolation Tables are designed for indoor use only.
Setup• To prevent the possibility of injury during an earthquake, make sure there are noobjects within the table's range of motion (the maximum displacement statedin the catalog) and that all personnel stay clear as well.
• To ensure proper performance, make sure the table load is within the weight
range stated in the catalog. Do not load the table with any object that has ahigh center of gravity or that would topple if pushed.
• For proper seismic isolation, the table must be placed on a level, even surface;
placement on a slanted or uneven surface could cause misalignment, undue
strain or irregular movement. When dealing with slanted or uneven surfaces,
please obtain professional assistance or consult your local distributor.
• Position the load so that its center of gravity is situated over the center of thetable. Improper positioning of a load or loading of objects that are outside thestated weight range could result in an unstable load and adversely affect thetable or its load.
• Make sure the table is locked in place with the anchoring hardware before
loading any object onto it. Make sure the table is locked before operating any
device loaded onto the table.
During an earthquake• If a seismic tremor occurs, move away from the seismic isolation table
immediately to prevent any possibility of injury through accidental contact withthe moving table.
• If an earthquake of intensity-level 6 or greater (on the Japanese scale) occurs, review the post-setup checklist in the instruction manual following theearthquake and follow the directions provided.

(1) This product is designed to attenuate horizontal seismic motion; it is not intended
to be effective against vertical seismic motion. This table will reduce the effect oftremors on an object loaded onto it, but there is no guarantee that the objectwill not move or topple.
(2) In the event of seismic motion stronger than this product is designed to absorb,
the table can be expected to strike the stopper, exerting an impact on any
object atop the table.
Warranty period
The warranty period is one year from the date of delivery.
Scope of warrantyThis warranty covers repairs to or replacement of a Seismic Isolation Table. It does notcover accidental damage, loss of business profits, interruption of business activities,
loss or alteration of data, or the like, arising from the use of this product or due to theproduct being out of service.
Disclaimer
THK is not liable for any Seismic Isolation Table malfunction arising from any of thefollowing:• Tsunami, lightning, flooding, fire, or another such accident or disaster.
• Damage to or collapse of a building due to an earthquake.
• Damage caused by the actions of a third party, intentional or unintentional
misuse of the product by the customer, or use of the product under abnormalconditions.
• Loading of an object that is not within the table-load weight range stated in theproduct specifications.
• Seismic input exceeding the product capacity stated in the specifications orinput exceeding the maximum displacement stated in the specifications.
• Damage to an object located within range of the table’s maximum displacement orcaused by the presence of an object that obstructs the table’s movement.
• Loading of an object that does not conform to the stated restrictions concerning
table loads.
• Placement or setup of a Seismic Isolation Table other than in conformity with theinstructions for correct placement and setup set forth in the instruction manual.
