Preparation
The following steps must always be observed when disassembling or removing magnets, guide rails and
gantries.
► Provide an empty box for the removal of each magnet. Only one magnet may be placed in each box!
► Switch off the machine, disconnect it from the power supply and secure it to prevent unauthorized
reactivation. Observe the instructions in section "1.2 Preparatory Work..." [ ➙ 89].
► Complete all necessary repair/replacement work before removing the magnet.
► Clear the area, in which the magnet is to be unpacked, of all ferromagnetic objects (steel particles,
screws, tools, and metal tables, etc.).
► Move all recording and measuring equipment to a safe place.
DANGER
Strong permanent magnet 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 at risk should avoid the immediate vicinity of the machine.
CAUTION
Danger of crushing
Danger of crushing for persons with passive metal implants (e.g. plates, screws).
► Do not reach or lean over into the machine when the protective covers are open.
► Do not bring any metal objects into the hazard area.
CAUTION
Strong permanent magnet fields
There is a risk that the strong magnetic fields could corrupt data on data media or check cards.
► Keep sensitive data supports away from the permanent magnets.
DANGER
Only SIPLACE engineers may remove the magnets, guide rails and gantries which relate to the
linear actuators.

Removing the Magnetic Track
DANGER
Observe the following points during removal:
► Persons wearing active implants (e.g. pacemakers) or other ferromagnetic prostheses are
explicitly forbidden to work on this equipment or approach the vicinity of it. Keep at a safe
distance from the magnet.
► Special precautions need to be taken due to the strong magnetic attraction forces in the di-
rect vicinity of the magnetic track and the moving primary unit. Heavy or wide objects made
of steel or iron must never be brought close to the magnetic track by hand. Because the
magnetic attraction forces are not visible, their effects close to the magnetic track are gen-
erally underestimated. The magnetic attraction force can start to take effect abruptly. In the
vicinity of ferromagnetic objects (made of steel or iron) of a similar size to that of the mag-
netic track, they can increase to several thousand newtons.
► Always wear appropriate work clothes and protective clothing (e.g. gloves, shoes, etc.)
when handling the magnetic track.
► Only suitably trained SIPLACE engineers are permitted to carry out assembly work and oth-
er tasks associated with replacing the magnetic track.
► In the event of emergencies, always have at least two wedges (approximately 10° through
15°) made of solid, non-magnetic material (e.g. plastic or aluminum) [Item.No.: 03097870-
xx] and a non-magnetic hammer (approximately 2 - 3 kg) [Item.No.: 03097897-xx] to hand.
These tools are required in the event of an emergency in order to separate parts that have
become magnetically attached to the magnetic track and to release any parts of the body
(finger, hand, foot) that may have become trapped.
► Never place the coil assembly of an iron-core motor directly on the magnetic track.
► Electronic equipment and measuring instruments can be damaged or destroyed by strong
magnetic fields. Do not place any equipment that contains magnetic components in the vi-
cinity of computers, monitors or magnetic data media (e.g. hard disks, credit cards, audio-
tapes, videotapes etc.).
► Always keep a distance of at least 45 cm (18 inches) between individual magnetic tracks
or between a magnetic track and other magnetic surfaces!

The magnetic track may only be removed by a SIPLACE engineer. Proceed as follows:
► Place the empty magnet packaging within easy reach of the machine. Only ever place one magnetic
track in each box.
► Remove the old magnetic track.
► Place the magnetic track in the packaging and close the lid.
► Remove the packaging containing the magnetic track from the working area.
► Repeat these steps for each magnetic track.
► Continue any repair/replacement work.

1.1.3.2 Installing the Magnetic Track
Installing the Magnetic Track
Install the magnetic track as follows:
► Place the magnet packaging, containing the magnet, within easy reach of the machine.
► Open the lid and remove the magnetic track.
► Install the magnetic track in the machine.
► Remove the empty packaging.
► Repeat these steps for each magnetic track.
► Continue any repair/replacement work.
DANGER
Packaging
► Only one magnet may be placed in each box!
► The following two warning labels must be attached to the box:
Warning label W202 Warning label magnets
DANGER
Observe the safety instructions
During installation, observe all safety information above.
