2.1.3.3 Safety of plant and equipment
Never make changes, however minor, unless you are totally aware of the effect they will have
on the overall functioning of the system.
The stations must always be set up, retooled and maintained by appropriately qualified per
-
sonnel.
Do not make modifications to the safety equipment. In particular, NEVER deactivate circuit-
breakers or remove safety devices. Safety instructions for laser units
Permission to operate components that are classified as lasers is withdrawn if
– Mechanical damage to the unit is observed, or
– Any work is done on the mechanical or electrical parts of the unit. Even damaged or miss
-
ing screw locking paint on laser components (e.g. cover plates, fasteners, adjusting po
-
tentiometer) counts as work.
– Only qualified personnel may replace laser components.
– Repairs to laser units are carried out at the ASM factory exclusively.
2.1.4 Safety instructions on permanent magnets
Powerful permanent magnets are used for the linear motors of the X and Y axes.

DANGER
Danger to life from powerful magnetic fields inside the machine!
When protective covers are opened inside the machine, the life of persons with the follow
-
ing passive or active implants is put at risk:
– Pacemakers
– Defibrillators
– Insulin pumps etc.
At-risk people must not stand in the immediate vicinity of the machine.
WARNING
DANGER OF CRUSHING!
There is a danger of crushing for persons with passive metal implants (e.g. plates,
screws).
Never reach into the machine when the protective covers are open and do not bend
over the open machine.
Do not bring any metal objects into the danger area.

CAUTION
Data loss due to powerful magnetic fields!
There is a risk that the powerful magnetic fields could corrupt data on data media or credit
cards and check cards.
Keep data carriers and check cards away from the machine.

Please note the following points when working on the permanent magnets:
People with active implants (e.g. heart pacemakers) or other ferromagnetic prostheses are
expressly prohibited from working on or coming near these devices. Always keep a safe dis
-
tance from the linear motor.
The powerful magnetic forces of attraction mean that particular caution is needed in the im
-
mediate vicinity of the magnet track and of the moving primary part. Never move heavy or
wide objects made of steel or iron manually into the vicinity of the magnet track. The magnetic
force of attraction is not visible, so its effects in the vicinity of the magnet track are generally
underestimated. The magnetic attraction can start suddenly, and can reach several thousand
Newtons in the vicinity of ferromagnetic objects (made of steel or iron) of similar size to the
magnet track.
Always wear suitable work and protective clothing (e.g. gloves and safety shoes, etc) when
handling the magnet track.
Only qualified personnel may carry out assembly work and other tasks when replacing the
magnet track.
In case of emergencies, always have at least two blocks (approx. 10° to 15°) made of a solid,
nonmagnetic material (e.g. aluminum) and a nonmagnetic hammer (approx. 2 to 3 kg) avail
-
able. These tools will be needed in an emergency to detach parts that are magnetically stuck
to the magnet track and possibly to release parts of the body caught between the two (fingers,
hand, foot). Never place the coil assembly of an iron-core motor directly on the magnet track.
Electronic devices and measuring instruments may be damaged or destroyed by powerful
magnetic fields. Do not place devices that contain magnetic components in the vicinity of
computers, monitors or magnetic data media (e.g.hard disks, credit cards, audio or video
tapes, etc).
Maintain a distance of at least 45 cm between individual magnet tracks or between a magnet
track and other magnetic surfaces.
The magnets must be disposed of correctly. A key part of correct disposal is the complete
demagnetization of the permanent magnets.
