5.2.4.2 Mounting rotor segments
WARNING
Danger of severe crushing injuries (step 6)
When highly magnetic rotor segments are slid into the T-sliding blocks, they are initially
drawn toward the mechanical stop. This movement of the rotor segment occurs without
externally applied force, and can be as much as about 1/3 of the length of the rotor
segment.
If the rotor segments are not placed correctly under the T-sliding blocks, the rotor
segment which is to be mounted can suddenly fly onto the neighboring previously
mounted rotor segment, when it is slid between the T-sliding blocks. This can cause
severe injuries to your fingers.
• Correctly place the rotor segments under the T-sliding blocks.
• When sliding the rotor segments between the T-sliding blocks, ensure that your
fingers cannot get trapped between two rotor segments.
WARNING
Danger of severe crushing injuries (step 10)
The force of attraction for the last rotor segment is significantly higher than for the
previously mounted rotor segments. When being inserted into the T-sliding blocks, the
last rotor segment is abruptly pulled towards the mechanical stop. This can severely
crush and injure your hands.
• Take extreme care when performing any work.
