2.3 Structural changes
Implementation of structural changes
Modifications, changes or reworking, e.g. additional threads,
holes, or safety devices, can damage the product or impair its
functionality or safety.
lStructural changes should only be made with the written
approval of SCHUNK.
2.4 Spare parts
Use of unauthorized spare parts
Using unauthorized spare parts can endanger personnel and
damage the product or cause it to malfunction.
lOnly use original spare parts and spares authorized by
SCHUNK.
2.5 Ambient conditions and operating conditions
Required ambient conditions and operating conditions
Incorrect ambient and operating conditions can make the
product unsafe, leading to the risk of serious injuries,
considerable material damage and/or a significant reduction in
the service life of the product
lMake sure that the product is only used within its defined
application parameters.

2.7 Chuck Jaws
Requirements of the chuck jaws
When using chuck jaws, please observe the following rules:
lChange chuck jaws at a standstill and without a clamped
workpiece.
lDo not use welded jaws.
l
Design the chuck jaws to be as low as possible. The clamping
point must be as close as possible to the housing. (clamping
points at a greater distance cause higher surface pressures in
the jaw guides and can significantly reduce the clamping force.)
lIf the clamping point is at a greater distance from the
housing, the operating pressure must be reduced.
l
After a collision, the clamping device and the chuck jaws must
be subjected to a crack detection test before being used again.
Replace damaged parts with original SCHUNK spare parts.
lThe chuck jaw mounting screws and if present, the T-nuts,
must be replaced if there are signs of wear or damage. Only
use screws of quality grade 12.9 in compliance with the
specified tightening torques. For clamping devices with fine
serration, the jaw mounting screws must be screwed into the
holes closest to the clamping point.
2.8 Personnel qualifications
Inadequate qualification of personnel
Any work on the product by inadequately qualified personnel can
lead to serious injuries and considerable material damage.
lAll work must be performed by appropriately qualified
personnel.
lPersonnel must have read and understood the complete
manual before beginning any work on the product.
lObserve country-specific accident prevention regulations and
the general safety notes.
The following personnel qualifications are required for the
various activities on the product:
Qualified electrician Qualified electricians have the professional training, knowledge,
and experience to work on electrical systems, to recognize and

Basic safety notes
12 05.00 | KSP3, KSP3-LH, KSP3-F | TANDEM Clamping Block | en | 1463318
2.16 Protection against dangerous movements
Safe condition
1. Clamping force block with workpiece:
Workpiece clamped outside the end positions of the clamping
force block with clamping pressure applied.
2. Clamping force block without workpiece, without clamping or
release pressure applied.
3. Clamping force block with spring force:
Clamped without energy without workpiece.
Special feature: Due to the built-in spring, an opened
clamping force block clamps without release pressure.
Unexpected clamping movements could result if the release
pressure fails. Take suitable measures, e.g. a pilot-controlled
check valve with manual venting.
Unexpected movements
If the system still retains residual energy, serious injuries can be
caused while working on the product.
lEstablish a safe state, switch off the energy supply, ensure
that no residual energy remains and secure against
inadvertent reactivation.
2.17 Notes on particular risks
WARNING
Risk of injury in the event of workpiece loss due to component
failure on the product as a result of exceeding the technical data.
lThe product is only allowed to be used within the scope of its
technical data.
WARNING
Risk of injury due to immediate closing of the product with high
spring force in the event of pneumatic pressure failure (AS variant).
lWait for the system to come to a complete standstill in the
safe state.
lDo not reach into the clamping force block.
WARNING
Danger of crushing due to the chuck jaws moving to the
workpiece during the clamping procedure when loading and
unloading manually.
lDo not reach between the workpiece and the chuck jaw
during the clamping procedure.
lImplement the safety functions according to the integrator's
risk assessment.

* Clamping force is the arithmetic sum of the individual forces occurring at the chuck jaws
at distance "H" (see also catalog).
** The increase in clamping caused by the spring assembly depends on the stroke due to
the spring tension. The maximum spring force is reached in the "open" state, the
minimum spring force in the "closed" state.
*** Distribution of the clamping position with 100 consecutive clamping operations.

4.2 Assembly of the Clamping Block on the machine table
34 Cylindrical pins Ø m6 (}8.3 [/39])
82 Fitting screw Ø f7 (}8.3 [/39])
84 Screw DIN EN ISO 4762
85 Clamping sleeve DIN EN ISO 13337
NOTE
lFor vertical installation, the openings of the coolant drain (V)
must always face downwards
lSurface "X" is parallel to the guideway of the base jaws (item
2) in order to be able to align the clamping force block on the
machine table or check the positioning.
Assembly with clamping sleeves:
Mount the clamping force block on the machine table together
with clamping sleeves (item 85) and screws (item 84).
Assembly with fitting screws:
There are two fittings in the housing (item 1) that, along with the
fitting screws (item 82), are used to center the clamping force
block on the machine table with repeat accuracy. Do not realign
the clamping force block after removing it from the machine
table (e.g. after replacing the seals). When using fitting screws
(item 82), these are used instead of the clamping sleeves (item
85) and two of the four screws (item 84).
Mounting with cylindrical pins (Z variant):
The clamping force block is fastened to the machine table with 4
screws (item 84). The two cylindrical pins (item 34) are used for
alignment with repeat accuracy. Do not realign the clamping
force block after removing it from the machine table (e.g. after
replacing the seals).

4.3 Mounting the clamping block on the base plate
(If the two parts are delivered separately)
When mounting TANDEM clamping force blocks on ABP-h plus
TANDEM base plates, use the shorter mounting screws included in
the base plate accessory kit instead of the standard mounting
screws (item 19) that come with the clamping force block.
For KSP3 100, KSP3-LH 100 and KSP3-F 100:
Use the M8 x 30 screws from the base plate accessory kit instead
of the M8 x 35 screws (item 84).
For KSP3 160, KSP3-LH 160 and KSP3-F 160:
Use the M10 x 35 screws from the base plate accessory kit instead
of the M10 x 40 screws (item 84).
For KSP3 250, KSP3-LH 250 and KSP3-F 250:
Use the M12 x 40 screws from the base plate accessory kit instead
of the M12 x 45 screws (item 84).
NOTE:
If the clamping force block and base plate are ordered
separately, the screws, O-rings and clamping sleeves for
assembling the parts are included in the accessory kit that comes
with the clamping force block.
lDo not open the connections on the front of the clamping
force block (I, II), or seal them with suitable dummy plugs (M5
or G1/8").
lInsert the clamping sleeves from the accessory pack into the
centering holes on the base plate.
lRemove the seal plugs from the base plate (internal air feed-
through III, IV) and insert the O-rings from the accessory pack
into the recesses for the air feed-throughs.
lMount the clamping force block onto the base plate.
NOTE:
The TANDEM base plates do not have a connection possibility for
the inductive proximity switches on the TANDEM clamping force
blocks.
The function for monitoring the jaw position can only be
connected externally. When joining, make sure the air feed-
throughs for the clamping system and the base plate are
precisely aligned.
lScrew the two parts together using the four screws (item 84)
from the accessory kit. In doing so, observe tightening
torques, }4.1 [/17].
lRemove the locking screws from the pneumatic connections
on the base plate.
lConnect the diaphragm pressure switch and set the switch to
the required minimum pressure.
