requires
For technical reasons or to save costs, mechanical limit stops are not always provided.
In safety-critical drives we therefore recommend using an additional safety limit switch
which in the event of a defective top limit switch protects against dangerous excess
travel and failure. The safety limit switch puts the drive permanently out of action as
soon as any overshooting of the regular limit switch takes place. The safety limit switch
is integrated directly into the drive and does not require any additional fitting. However
this can increase the fitting dimension of the drive by 23 mm.
Caution!
Only ever connect or disconnect electrical components when they are voltage-free.
