2.6.4
Protection during handling and assembly
Bosch Rexroth AG R911389762_Edition 04
●
Extreme caution during handling of motor components with permanent
magnets. Do never underestimate strong attractive forces.
●
Never work alone.
●
Use personal safety equipment (e.g. protective gloves, protective
glasses).
●
Unpack single motor components with permanent magnets immediately
prior mounting.
●
Do not unpack several motor components with permanent magnets or
directly place them side by side at your working space.
●
Do not bring magnetized or magnetizable materials in the area of per‐
manent magnets. If using magnetizable tools cannot be avoided, hold
on the tool very tight, move carefully and observe the attractive force ef‐
fect of the permanent magnets.
Behavior in the case of accidents with permanent magnets
During work with permanent magnets, the following emergency tools must be
ready to use in the case of an accident to release impacted body parts (like
fingers, hands, arms a.s.o.):
●
Hammer (3-5kg) made of non-magnetized material like brass
●
Minimum 2 wedges with approx. 10 - 15 ° lip angles made of non-mag‐
netized material like brass, wood or similar to impact driving into the cut‐
ting slit.
●
A crowbar made of brass.
In the case of an accident:
●
Keep calm!
●
If the machine is live, immediately de-energize (emergency button).
●
Give first aid or request appropriate help (e.g. emergency doctor).
●
Disconnect magnetic adherent parts with the emergency tools. There‐
fore, beat the wedges with a hammer into the cutting slit to free the
caught body parts.
Motor components with permanent magnets (e.g. secondary parts of a syn‐
chronous linear motor or rotor of a synchronous kit motor) create very strong
attractive forces from ferromagnetic parts like further motor components with
permanent magnets or parts of iron, nickel or cobalt.
Please observe the safety notes about strong attractive forces of permanent
magnets under
chapter 2.6.3 "Protection against magnetic and electromag‐
netic fields" on page
5.
The attractive forces of the permanent magnets influence all magnetizable
materials. Especially in an area < 100 mm, the attractive forces rise. Sur‐
rounding components can abruptly and inadvertently be attracted by the per‐
manent magnets. Apart from crushing hazard, even the danger of chipping
recalcitrant material, causing eye injury, exists.
Use the origin package of the motor components for transport and storage
only. The origin package of Rexroth is constructed in such a way that the mo‐
tor components with the permanent magnets are positioned within the pack‐
age with suitable distance, providing that the package is correctly used.
Observe the following instructions during unpacking and handling.
