Lenze Smart Motor m300-E - Residual Hazards

Residual hazards
Even if notes given are taken into c
onsideraon and protecve measures are implemented,
the occurrence of residual risks cannot be fully prevented.
The user must take the residual hazards menoned into consideraon in the risk assessment
for his/her machine/system.
If the above is disregarded, this can lead to severe injuries to persons and damage to
property!
