Components with permanent magnets
The rotors of the 1FW6 built-in torque motors described in this manual contain permanent
magnets.

Risk of death as a result of permanent magnet fields
The permanent magnets in the motors represents a danger for people with active medical
implants, who come close to the motors. This is also the case when the motor is switched
off.
Examples of active medical implants include: Heart pacemakers, insulin pumps.
• If you are affected, stay a minimum distance of 300 mm from the permanent magnets
(tripping threshold for static magnetic fields of 0.5 mT according to the Directive
2013/35/EU).
With regard to the effect of strong magnetic fields on people, in Germany the DGUV
regulation 103-013 "Electromagnetic fields" of the German Social Accident Insurance must
be complied with! This regulation lists all of the requirements that must be observed at
workplaces. In other countries, the relevant applicable national and local regulations and
requirements must be taken into account.
