lMake sure that the product is a sufficient size for the
application.
lMake sure that the contact surfaces of the interface and
recesses indented to the locating surfaces above the mounting
locations are always clean.
lUnder all circumstances, prevent any type of chips from
entering the interface and prevent cooling emulsion from
seeping into the interface. This may occur particularly for
vertical alignment of the clamping pin axis. The best way to
ensure both of these requirements is to use the SDE protection
covers or the cone seal intended for the quick-change pallet
system. If the interface should fill with cooling emulsion,
initiate the unlocking process and allow the interface to dry
out in actuated state. Carefully perform blowing out with
compressed air only using the required protective equipment.
lOnly use high-quality cooling emulsions with anti-corrosive
additives during processing.
lProtect the cone seal from direct high spray pressure with
cooling emulsion.

* Holding force when fastening the clamping pin with cylindrical screw – DIN EN ISO 4762/12.9
The actuating pressure for the turbo function must not exceed
6 bar.
A separate maintenance unit must be used for the air supply.
The quick-change pallet system is designed for operation with
dry compressed air. If oiled compressed air is used for
operation, this must be done every time. For an air volume of
1000 liters, the compressed air should be prepared with 1 to 2
drops of oil . This corresponds to approx. 1400 clamping cycles
with NSE3 138.

3.2.1 Suitability for welding applications
The clamping device can be used for welding applications with a
welding current of up to 525 A. The welding current is allowed
to flow through the clamping device.
CAUTION
In welding applications, special care must be taken to ensure
that the operating temperature of the clamping device is not
exceeded due to heat conduction in the workpiece.
CAUTION
The contact surfaces of the workpiece and the clamping bolt
must always be kept clean to ensure the best possible contact
with the clamping device.
If the quick-change pallet system is to be used outside the
specified welding currents, please contact your SCHUNK contact
person.

4.1 Pre-assembly
Request our installation drawings if installing the module in
the customer's clamping stations yourself.
The installation position must be observed when performing the
installation yourself.
1 Partial installation 2 Do not use 3 Full installation
CAUTION
With installation location 2, the clamping slide can be blocked
by chips and dirt. For this reason, do not use this installation
position. Otherwise make sure to fit deeper clearance in front
of the movable clamping slides.
lDamage to the clamping module is possible.
4.2 Installing and connecting
WARNING
Risk of injury due to unexpected movements!
If the power supply is switched on or residual energy remains in
the system, components can move unexpectedly and cause
serious injuries.
lBefore starting any work on the product: Switch off the power
supply and secure against restarting.
lMake sure, that no residual energy remains in the system.
WARNING
Risk of injury due to unexpected movements when installing
and removing the cone seal!
This can cause components to move unexpectedly when working
on the cone seal, resulting in injuries.
lBefore starting all work on the product, refer to the cone seal
chapter. }4.3.7 [/30]

4.3 Fastening and connection
Flatness
If several linked clamping modules are mounted, make sure that the
flatness and height deviation of the outer ring bearing surfaces from
clamping module to clamping module (with respect to a 200 mm
gauge) is ≤ 0.02 mm. The gauge deviation from module to module
must not be greater than ±0.015 mm. The position tolerance of all
module seats must not exceed a total value of 0.05 mm.
Redundancy
Due to redundancy, a clamping pin with positioning accuracy in
one direction (SPB 40, positioned diamond shaped) must be used
for clamping systems that are more than 160 mm apart or that do
not show a positioning tolerance of ± 0.01 mm. The diamond-
shaped alignment surfaces on the SPB 40 clamping pin must be
aligned at right angles to the longitudinal axis between clamping
pins SPA 40 and SPB 40. This allows for compensation of a
distance offset between the clamping areas to be aligned. For
the clamping areas that are not intended for aligning the device
or pallet, clamping pins with centering clearance (SPC 40) must
be used (also refer to the chapter "Clamping pins"}4.4 [/31]).
