DANGER: STRONG MAGNETIC FIELDS
Fatal hazard: persons with active implants (e.g. pacemakers, defibrillators, insulin pumps etc.)
are at risk from strong permanent magnetic fields inside the machine.
Persons are risk should avoid the immediate vicinity of the machine.
CAUTION: DANGER OF CRUSHING
Risk of crushing/trapping for persons with passive metal implants (e.g. plates, screws).
X Do not reach or lean over into the machine when the protective cover is open.
X Do not bring any metal objects into the area.
ATTENTION: STRONG MAGNETIC FIELDS
There is a risk that the strong magnetic fields could corrupt data on data media or check cards.
X Keep sensitive data carriers away from the permanent magnets.

4.1.1.3 Safety Note EA-SD-001
Removing Magnets
When removing a magnet, perform the following steps:
X Perform any necessary repairs/replacements before removing the magnet.
X Disconnect the placement system from the power supply.
X Remove all ferromagnetic objects (steel particles, screws, tools, metal tables) from the area in which
the magnet is to be unpacked and place all recording and measuring devices in a safe place.
X Place the empty magnet packaging, provided by Siemens (00374412-01), within easy reach of the
machine. Only place one magnetic track in each box.
X Dismantle the old magnetic track.
X Place this magnetic track in the packaging and close the lid. The packaging must be labeled with the
following two warnings:
DANGER: Important safety note EA-SD-001
RISK OF INJURY AND/OR DAMAGE TO PROPERTY
X Only Siemens technicians may remove magnets.
ATTENTION:
The magnetic track may only be removed by Siemens technicians.
DANGER: FATAL HAZARD
X Persons with active implants (e.g. pacemakers) or other ferromagnetic implants are expressly
prohibited from working with these devices or from being in their vicinity.
Keep a safe distance from the motor!
X Due to the powerful magnetic forces of attraction, special safety measures must be observed
when in the direct vicinity of the magnetic track or the flexible primary part. Never manually
move heavy or wide steel or iron objects near to the magnetic track. Since the magnetic
forces of attraction are not visible, it is easy to underestimate their effect in the vicinity of the
magnetic track. These forces of attraction can take effect very abruptly. This means that,
when near to the track, ferromagnetic objects (of steel or iron) which are around the same
size as the magnetic track, can suddenly develop a force several thousand Newton strong.
X When handling the magnetic track, always wear suitable protective clothing (e.g. gloves,
shoes etc.).
X Only specially trained Siemens technicians may perform assembly work and other tasks
concerning the replacement of the magnetic track.
X In case of emergencies, always have two solid, nonmagnetic wedges (approx. .10° to 15°,
made of a material like aluminum) ready, plus a nonmagnetic hammer (approx. 2 to 3 kg).
These tools are needed in emergencies, to release objects which are stuck to the magnetic
track and to free any trapped limbs (fingers, hand, foot). Never place the inductor coil
assembly of an iron core motor directly on the magnetic track.
X Electronic equipment and measuring devices could be damaged or destroyed by powerful
magnetic fields. Never place any devices with magnetic components near computers,
monitors or magnetic data carriers (e.g. hard disks, credit cards, audio and video tapes etc.).
DANGER: Keep a safe distance!
X Keep a distance of at least 45 cm between a magnetic track and other magnetic surfaces.
