General safety instructions
Danger!
"
The elevator machine has attachment points: integrally cast eyelets or screwed-on eye bolts, eye
plates or steel cable loops. The attachment points are designed exclusively for transporting the
elevator machine including brake and traction sheave. Do not lift other loads such as bolted on
components, ropes lying on top, etc. with the attachment points. Suitable lifting gear must be used.
Danger!
Warning of hand injuries!
"
Risk of injury from reaching into the rope guard.
"
Do not carry out any activities during operation.
"
Only perform maintenance work on the drive when stopped!
"
If the elevator machine is not energised, no electric torque is available. Releasing the brakes can
cause uncontrolled acceleration of the elevator.
We recommend short-circuiting the windings of the de-energised elevator machine to generate a
brake torque dependent on the speed.
In the event of a short-circuit, a short-circuit current of at least the level of the rated current is
fl
owing.
The windings may not be short-circuited when the elevator machine is energised.
3 Safety precautions

In case safety precautions are not taken:
✓
Can it lead to death or severe injury or signi
fi

Brake malfunction may result!
On installed drives, before replacement of the brake, following safety measures have to be taken:
"
Counterweight has to rest on the buffer.
"
Cabin has to be suspended.
✓
Thereby the ropes are unburdened!
