Safety measures for operating
personnel
In the European Community (EU), directive 2004/40/EC specifies minimum
requirements for protection of the safety and health of employees from haz‐
ards due to electromagnetic and magnetic fields. Regulations and guides for
machine manufacturers and machine operators are included in the following
documents:
●
Standard EN 50499 (Germany: DIN EN 50 499, DIN VDE 0808-499)
● Standard EN 50527 (Germany: DIN VDE 0848-3)
● In Germany: Accident prevention regulations BGV/GUV-V B11
This list does not claim to be exhaustive. Machine manufacturers and ma‐
chine operators are required to define the regulations applicable on site and
the occupational health and safety measures to be applied for working in the
area of exposition. The decisive factors are not the electromagnetic proper‐
ties of individual machine components but the effective overall exposition in
electrical, magnetic and electromagnetic fields in the actual working area.
Construction information During construction of the machine, suitable covers and safety equipment for
safe operation must be applied.
●
During construction of the machine, observe applicable standards and
regulations on marking of and access to exposition areas.
● Prevent any access of operating personnel in the motion range of mo‐
tors during operation.
● Prevent any contamination, chips and dirt in the motion range of motors.
Notes on transport For shipping by air freight of magnetic components, the limit values for mag‐
netic flux density in all directions in accordance with IATA953 must be com‐
plied with. All rotors of Bosch Rexroth synchronous motors comply with cate‐
gory I according to the figure below. Depending on their geometry and con‐
struction, the secondary parts of Bosch Rexroth linear motors comply with
one of the three listed categories. Before shipping, the category of the pack‐
age must be determined.
Category
Distance to the
edge of the pack‐
age
Flux density Measure
I 2.1 m
≤ 0.525 µT
≤ 5.25 mG
Package does not require decla‐
ration and marking for shipping.
II 4.6 m
≤ 0.525 µT
≤ 5.25 mG
Declaration and marking as
magnetic material is required.
III 4.6 m
> 0.525 µT
> 5.25 mG
Shipping requires prior approval
of responsible national authori‐
ties in the country of dispatch
and the state of the air freight
carrier.

9.8 Noise emission
The noise emission of synchronous linear drives can be compared with con‐
ventional inverter-operated feed drives. Empirically, it is dependent from the
following factors:
●
the employed linear guides (velocity-related travel noise),
● used length measuring system,
