2.13 Fundamental dangers
General
lObserve safety distances.
lNever deactivate safety installations.
lBefore commissioning the product, take suitable protective
measures to secure the danger zone.
lProvide a secured protective enclosure for automated use of
the clamping device.
lDisconnect power sources before assembly, conversion,

energy remains in the system.
lDo not reach into the open mechanism or movement area of
the product during operation.
2.13.1 Protection during handling and assembly

Incorrect handling and assembly may impair the product's safety
and cause serious injuries and considerable material damage.
lHave all work carried out by appropriately qualified
personnel.
lFor all work, secure the product against accidental operation.
lObserve the relevant accident prevention rules.
lUse suitable assembly and transport equipment and take
precautions to prevent jamming and crushing.
Incorrect lifting of loads
Falling loads may cause serious injuries and even death.
lStand clear of suspended loads and do not step into their
swiveling range.

2.13.2 Protection during commissioning and operation
Falling or violently ejected components
Falling and ejected parts or components can lead to serious
injury or death.
lTake suitable protective measures to secure the danger zone.

Basic safety notes
01.00 | KSP3-BWA, KSP3-LH-BWA | TANDEM Clamping Block | en | 1485610 13
2.13.3 Protection against dangerous movements
Unexpected movements
Residual energy in the system may cause serious injuries while
working with the product.
lSwitch off the energy supply, ensure that no residual energy
remains and secure against inadvertent reactivation.
lNever rely solely on the response of the monitoring function
(dynamic pressure monitoring with pressure sensors) to avert
danger.
Assume that the drive movement is faulty as long is the
installed monitors are not effective, since the effect depends
on the control and the current operating state of the drive.
Perform maintenance, modification and attachment work
outside of the danger zone defined by the movement range.
lTo avoid accidents and/or material damage, human access to
the range of movement of the clamping force block and its
automated system for jaw changing must be restricted. Apply
technical safety measures to limit / prevent accidental access
for people in this area. The protection cover and protective
fence must be rigid enough to withstand the maximum
possible movement energy. EMERGENCY STOP switches must be
easily and quickly accessible. Before commissioning the
machine or automated system, check that the EMERGENCY STOP
system is working. Prevent operation of the machine if this
protective equipment does not function correctly.
2.13.4 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).

* Clamping force is the arithmetic sum of the individual forces occurring at the chuck
jaws at a distance of "H" (see catalog ).
** The clamping force increase caused by the spring assembly depends on the stroke
because of 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.
**** When using an ABP-A base plate, the maximum pressure must be limited to 7 bar.

NOTE
lFor vertical installation, the opening of the coolant drain (V)
must always face downwards
lSurface »X« is parallel to the guideway of the base jaws (2) in
order to be able to align the clamping force block on the
machine table or check the positioning.
lFor size KSP3 250-BWA, KSP3- LH 250-BWA, the sides »Y«
contain transport thread M10, 2x diagonally opposite
Mounting with clamping sleeves:
Mount the clamping force block on the machine table together
with clamping sleeves (85) and screws (84).
Mounting with fitting screws:
There are two fittings in the housing (1) that, along with the
fitting screws (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 (82),
these are used instead of the clamping sleeves (85) and two of
the four screws (84).
Centering with cylindrical pins (Z variant):
The clamping force block is fastened to the machine table with 4
screws (84). The two cylindrical pins (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).
5.2 Mounting the clamping force block on the base plate (If
both parts are delivered separately)
When mounting TANDEM clamping force blocks on the ABP-h
plus TANDEM base plates, use the shorter mounting screws
included in the base plate accessory kit instead of the standard
mounting screws (19) that come with the clamping force block.
For KSP3 100-BWA, KSP3-LH 100-BWA:
the M8 x 30 screws from the base plate accessory kit are used
instead of the M8 x 35 screws (84).
For KSP3 160-BWA, KSP3-LH 160-BWA:
the M10 x 35 screws from the base plate accessory kit are used
instead of the M10 x 40 screws (84).
For KSP3 250-BWA, KSP3-LH 250-BWA:
the M12 x 40 screws from the base plate accessory kit are used
instead of the M12 x 45 screws (84).
