Risk to persons as a result of strong magnetic fields
WARNING
Risk of death as a result of permanent magnet fields
Even when the motor is switched off, the permanent magnets can put people with
active medical implants at risk if they are close to the motor.
Examples of active medical implants include: Heart pacemakers, insulin pumps.
• If you are affected, keep a minimum distance of 800 mm from the permanent
magnets (tripping threshold for static magnetic fields of 0.5 mT according to
Directive 2013/35/EU).
With regard to the effect of strong magnetic fields on people, the DGUV rule 103-013
"Electromagnetic Fields" of the German Social Accident Insurance applies in Germany.
This rule specifies all the requirements that must be observed in the workplace. In other
countries, the relevant applicable national and local regulations and requirements must
be taken into account.
When dealing with magnetic fields, you must take into account the requirements of
DGUV rule 103-013 of the German Social Accident Insurance.
CAUTION
Safety distance to the rotor segment
The rotor segment magnetic fields are permanent. When you come into direct bodily
contact with the rotor segments, a static magnetic flux density of 2 T is not exceeded.
• Observe DGUV rule 103-013, § 14 "Systems with high static magnetic fields".
WARNING
Risk of electric shock
Voltage is induced each time the rotor segment moves with respect to the stator
segment - and vice versa. If you touch the power connections you may suffer an electric
shock.
• Do not touch the power connections.
• Connect the motor cable ports correctly, or insulate them properly.
