2.12.1 Protection during handling and assembly
Incorrect 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.
lNever move loads without supervision.
lDo not leave suspended loads unattended.
2.12.2 Protection during commissioning and operation
Falling or violently ejected components
Falling and violently ejected components can cause serious
injuries and even death.
lTake appropriate protective measures to secure the danger
zone.
lNever step into the danger zone during operation.
Manual loading
lModule is closed, clamping plate is lying on clamping slides.
If the modules are opened, the clamping plate falls down.
This poses a risk of crushing.

Basic safety notes
12 08.00 | NSE mini 90, NSE-M mini 90 | VERO-S quick-change pallet system | en | 1372754
2.12.3 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
to avert danger. Until the installed monitors become effective,
it must be assumed that the drive movement is faulty, with its
action being dependent on the control unit and the current
operating condition of the drive. Perform maintenance work,
modifications, and attachments outside the danger zone
defined by the movement range.
lTo avoid accidents and/or material damage, human access to
the movement range of the machine must be restricted. Limit/
prevent accidental access for people in this area due through
technical safety measures. The protective 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 starting up 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.
2.12.4 Notes on particular risks
DANGER
Risk of fatal injury from suspended loads!
Falling loads can cause serious injuries and even death.
lStand clear of suspended loads and do not step within their
swiveling range.
lNever move loads without supervision.
lDo not leave suspended loads unattended.
lWear suitable protective equipment.

Basic safety notes

WARNING
Risk of injury due to falling device, pallet or workpiece if the
clamping pin is loosened erroneously or as a result of
negligence.
lDuring operation, erroneous or negligent loosening of the
clamping pin must be prevented using suitable
countermeasures (disconnecting the power supply after
locking, use of check valves or safety switches).
lThe machines and equipment must fulfill the minimum
requirements of the EC Machinery Directive 2006/42/EC;
specifically, they must have effective technical measures to
protect against potential mechanical hazards.
lWear personal protective equipment.
WARNING
Risk of injury when the clamping pin axis is in a horizontal
position or during overhead application, as a result of the
device or pallet falling down.
lUse a crane or a transport truck when transporting.
lDuring horizontal or overhead applications, the device or
pallet must be secured before loosening to prevent it from
falling.
WARNING
The system clamps using spring force. Risk of injury due to
parts automatically moving to their end positions following
actuation of an "emergency stop" or after switching off the
power supply.
lWait for the system to shut down completely.
lDo not reach into the clamping module.
lUse pressure maintenance valves.
CAUTION
Risk of injury due to impurities (e.g. metal chips) in the
exhaust and air purge connections of the clamping station.
lTake appropriate protective measures to secure the danger
zone.
lWear personal protective equipment (safety goggles).

Basic safety notes
14 08.00 | NSE mini 90, NSE-M mini 90 | VERO-S quick-change pallet system | en | 1372754

operational environment is not clean (e.g. contaminated with
cooling lubricants or oil).
lEnsure that the working environment is clean before starting
assembly and installation work.
lWear suitable safety boots.
lFollow the safety and accident-prevention regulations when
operating the quick-change pallet system, especially when
working with machine tools and other technical equipment.

3.1 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.
NOTICE
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.
NOTICE
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 Assembly
4.1 Pre-assembly measures
Carefully lift the product out of the packaging (e.g. with suitable
lifting equipment).
CAUTION
Risk of injury due to sharp edges and rough or slippery surfaces
Wear personal protective equipment, particularly protective
gloves.
Check that the delivery is complete and that there is no transport
damage.
4.2 General assembly notes
The item numbers specified for the corresponding individual
components relate to chapter drawings.}9 [/40]
Assembly, dismantling and modification work on the quick-
change pallet system may only be carried out by specialist
personnel.
Request our installation drawings if doing the installation
yourself.
Disconnect the power supply lines and ensure that there is no
residual energy in the system before performing assembly,
modification, maintenance, or adjustment work on the
pneumatically actuated quick-change pallet system.
Wear protective clothing (gloves, protective shoes).
Access to the drive piston (pos. 4) on the side must be ensured
during the assembly of the manually actuated quick-change
pallet system, in particular in the event of clamped clamping
pallets. Check whether the drive piston is easy to access in
order to open or close the clamping module prior to the
installation.
WARNING
Risk of injury due to dropping the quick-change pallet system
during transport
Transport with care.

Assembly
08.00 | NSE mini 90, NSE-M mini 90 | VERO-S quick-change pallet system | en | 1372754 17
CAUTION
Risk of injury due to crushing
Install the quick-change pallet system carefully.
Do not place any limbs into the gaps or between the clamping
station and the machine.
If several linked clamping units are mounted, make sure that the
flatness and height deviation of the locating surface from
module to module (based on a gauge of 200 mm) lies within 0.01
mm. The interface position deviation must not exceed ±0.015
mm.
Due to redundancy, the clamping pins with positioning accuracy
in one direction (SPB mini 20) should be used for clamping
systems that are more than 160 mm apart or that do not show a
positioning tolerance of ±0.01 mm. For the clamping areas that
are not intended for alignment of the device or pallet, clamping
pins with centering clearance (SPB mini 20) can be used (also
refer to chapter "Clamping pins SPA 20 mini, SPB 20 mini, SPC 20
mini" }4.4 [/24]).
NOTE
When connecting the pneumatically actuated quick-change
pallet system, ensure that it is only possible to completely
ventilate the piston chamber via the air connection on the base
side during the locking process. The relevant valves or shut-off
valves should therefore be equipped with load relief. This also
applies to the turbo connection.
If the turbo connection is not used, the relevant side of the
piston must be able to ventilate. Be sure to take the ventilation
methods into account (see Fig. "Air bleed screw via turbo
connection").

Assembly

Turbo connection
The connection must be sealed
with an O-ring in the installation
space
Provide ventilation
Ventilation via turbo connection
When dismantling the clamping system from the machine table,
the corresponding openings must be secured with set-screws to
prevent ingress of dirt.
If several units are activated via shared hose lines, feed lines
with the following minimum cross-sections must be used.
Number of modules at least nominal hose width
1, 2 4 mm
3, 4, 5, 6 6 mm
