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.

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.

Installation
The following descriptions refer to a facility or door which is not further defined. The facility or
door manufacturer's specifications must also be observed.
Warning – Injury or danger to life possible!
Use a lifting device with sufficient load-carrying capacity for installation tasks.
▶ Completely grease the door shaft.

▶ Attach safety brake. Observe rotating
direction.

▶ Tighten all connection elements (M12) with
a torque of 75 Nm. Install all further
connection elements according to the
specifications of the door or facility
manufacturer.

6Electrical installation
Warning – Danger to life due to electrical current!
Disconnect the cables (mains OFF) and check that the supply is off
Observe applicable regulations and standards
Ensure proper electrical connection
Use suitable tools
The integrated safety switch of the safety brake functions as an NC contact. Connect the
cable of the safety switch to the EMERGENCY STOP input of the door control. When the
safety brake is activated, the electrical circuit is interrupted and the electrical operation of the
gate is no longer possible.
Carrying out the electrical installation
Cable of the safety brake's safety switch (➊) Connection of the cable to the
EMERGENCY STOP input of the door
control (➋)
Warning – Injury or danger to life possible!
The safety switch of the safety brake must not be connected to the drive unit.
Completing the electrical installation
Install cable entries and/or cable glands.

7Safety brake activation
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).
Warning!
De-energise the facility and secure against unintended switching-on.
Secure door/load against falling.
Rectify the cause of tripping (drive unit, chain, etc.).
Any time the safety brake has been tripped, it must be disassembled and checked. If the
control pointer (➊) is damaged, the safety brake must be replaced.
Unscrew (3xT20)
cover (aluminium)
and assess control
pointer (➊).

8Repairs
If the control pointer is not damaged (see Safety brake activation – Ⓒ), the safety brake can
be repaired.
▶ Rotate hollow shaft in OPEN direction by
approx. 90°.

▶ Press the red plunger back into the
housing.
▶ The safety brake is ready for operation
again.

9Completion of initial operation / inspection
Check the following components and after that, mount all covers.
Mounting
Check all mounting elements (consoles, screws, retaining rings etc.) for tightness and
impeccable condition.
Electric wiring
Check connection cables and cables for damage or pinches.
Check screw and plug connections for correct seating and electrical contact.
Mounting position
On the basis of the OBEN/TOP and AB/DOWN markings and by checking.
Maintenance/inspection
The safety brake requires no maintenance.
The safety brake is type-approved. Checking for correct functioning is not required and
inadmissible once the safety brake is installed.
Entire safety brake
Note!
Have a specialist check the safety brake once a year.
Shorter inspection interval for frequently used equipment or doors.
Observe the applicable regulations and standards
