1General safety information
Specified normal use
The safety brake is intended for loads which must be secured against falling down. The
device can be used in potentially explosive atmospheres according to the ATEX directive
2014/34/EU. The safety brake is mounted directly onto the shaft. The safety brake is
activated automatically in the case of trapping. The function depends on speed and rotary
direction. The safe operation is only guaranteed with specified normal use. No liability for
damage caused by other applications or non-observance of the information in the manual.
Modifications are only permitted with the agreement of the manufacturer. Otherwise the
Manufacturer’s Declaration shall be rendered null and void.
Safety information
Installation and commissioning are to be carried out by skilled personnel only.
Only trained electrical craftsmen are permitted to work on electrical equipment. They must
assess the tasks assigned to them, recognise potential danger zones and be able to take
appropriate safety measures.
Installation work is only to be carried out with the supply off.
Observe the applicable regulations and standards.
Coverings and protective devices
Do not operate unless corresponding coverings and protective devices are installed.
Ensure that cable glands are correctly tightened.
Spare parts
Only use original spare parts.

(see technical data)
In normal operation, the safety brake functions similar to pedestal bearings. The safety brake
is tripped as soon as the maximum operating speed in DOWN direction is exceeded. This
results in the following reactions:
The shaft is blocked in DOWN direction (➊).
The safety switch is actuated to interrupt the control current (➋).
Release is optically indicated by a red plunger (➌).

5Mechanical installation
Requirements
The permissible loads on walls, mountings, connection and transmission elements must not
be exceeded even for maximum locking torque (▶ observe technical data).
Connection elements:
▶ Use self-locking
connection elements with
a minimum strength of
800 N/mm2 (8.8).
▶ Use a screw that
precisely fits the hole.
▶ Use adequately
dimensioned washers for
elongated holes.
