Assembly
4 Assembly
4.1 General Installation Notes
Pre-assembly measures
Lift the quick-change pallet system carefully out of the packaging
(e.g. using suitable lifting equipment). For clamping stations NSL3
400 or higher, eye bolts are supplied for transporting the clamping
station. The eye bolts are to be mounted into the transport
threads on the base plate and then removed after assembly.
Before assembly, the interfaces (bottom of the clamping station
and support area of the machine table) must be clean and free of
any contamination or damage.
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.
•Before starting any work on the product: Switch off the power
supply and secure against restarting.
•Make sure, that no residual energy remains in the system.
CAUTION
Danger of injury due to sharp edges and rough or slippery
surfaces
•Wear personal protective equipment, particularly protective
gloves.

4.2 Aligning the clamping station
The clamping station can be aligned with loose T-nuts along an
aligning groove on the machine table. At least two T-nuts offset
lengthwise are provided and their size is matched to the aligning
groove on the machine table. The T-nuts are not included in the
scope of delivery of the clamping station.
Alignment using T-nuts
4.3 Mounting and connecting the clamping station
Flatness and distances
In order to assemble the clamping station, the clamping surface
must have a flatness of ≤ 0.03 mm (based on the entire support
areas of the clamping station). The clamping zone must have
sufficient rigidity in order to ensure the relative flatness of the
clamping modules. If several clamping stations are interlinked,
make sure that the flatness and height deviation of the locating
surfaces between modules (based on a 200 mm gauge for bore
holes) is ≤ 0.03 mm. The gauge deviation between the separate
clamping stations must not exceed ± 0.015 mm from module to
module.
Redundancy
For the sake of conformity, clamping pins with positioning
accuracy in one direction (SPB 40) should be used for clamping
modules inside a clamping station or multiple linked clamping
stations 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 aligning the device or pallet, clamping pins
with centering clearance (SPC 40) can be used (also refer to
chapter "Clamping pins" }4.4 [/30]).

Assembly
Even height of the clamping modules
Even height of the clamping modules inside a clamping station is
only ensured when in a clamped state. Set-up is performed by
means of individually inserted holes or optionally available clamp
blanks. The clamping station or the clamp blanks must be fastened
using adequately dimensioned mounting screws in accordance
with DIN EN ISO 4762 starting with thread size M10. The
prescribed arrangement for the BRR 50 clamp blanks can be found
in the following clamping diagram. Permitted ranges for mounting
holes can be found in the attached bore hole drawings. Clamping
stations from size NSL3 400 already have holes for at least two
M10 mounting screws. The mounting points are offset centrally
between the clamping modules at a distance of 200 mm. Due to
the additional fitting, increased rigidity on the machine table is
achieved for the clamping station when fastening with clamp
blanks.

Note
The clamping range of the NSL3 300-200 is based on the clamping
scheme of the NSL3 400. Here, optionally available BRR50 clamp
blanks are to be attached to four clamping points distributed
evenly on the round outer diameter.
Cylindrical clamps are versatile fixturing elements
The mounting holes are machined by the customer
Flexible mounting possibilities for common T-nut distances
Mounting clamp blanks
Alternating ventilation for the clamping modules when
connecting and disconnecting the air supply at the clamping
station
When connecting the clamping station, it must be taken into
consideration that complete ventilation of the piston chambers in
all clamping modules during the locking process is only possible via
the air connection. For safe pressure ventilation, use the
appropriate valves, shut-off valves with discharge or sealing
nipples with air bleed screw.
NSL3 clamping stations without turbo function
For NSL3 clamping stations without turbo function, ventilation of
the clamping modules occurs as a result of pressure applied to the
unlocking connection via its own ventilation hole along the bottom
of the base plate of the clamping station used. When setting up a
clamping station without turbo function on the machine table,
make sure that the vented compressed air is able to escape
