2.1.4 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Permission to operate components that are classified as lasers is withdrawn if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 ASM Assembly Systems GmbH&Co.KG service engineers or the machine owner's
service engineers, who have been trained by ASM, may replace laser components.
– Repairs to laser assemblies may only be performed by ASM Assembly Systems
GmbH&Co.KG at their factory.
2.1.5 Safety instructions on permanent magnets
Powerful permanent magnets are used for the linear motors of the X and Y axes.
DANGER OF DEATH
POWERFUL PERMANENT MAGNETIC FIELDS INSIDE THE MACHINE 2
The life of persons with passive or active implants such as pacemakers, defibrillators, insulin
pumps etc. is put at risk inside the machine if protective covers are opened.
At-risk people must not stand in the immediate vicinity of the machine.
WARNING
DANGER OF CRUSHING 2
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
POWERFUL PERMANENT MAGNETIC FIELDS 2
There is a risk that the powerful magnetic fields could corrupt data on data media or credit cards
and check cards.
Fig. 2.1 - 1 Position of the permanent magnets for the linear drives (example of SX4)
(1) permanent magnets for X linear motors
(2) Permanent magnets for Y linear motors
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 suitably trained SIPLACE engineers 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 de-
magnetization of the permanent magnets.
