2 Safety
2.1 Intended use
The product safety bumper is used as a safeguard for dangerous closing edges indoors and
outdoors.
Typical applications are for protection of self-propelled or hard-to-see vehicles, traversing
devices, as a guard for shear edges on lifting devices and platforms, in industrial and theatre
technology, as well as for buffering lifting and traversing devices in airports to protect the
aircraft skin.
Safety bumpers protect human body parts such as hands, arms, legs, head and torso.
Design and functioning principle

Safety technology
4 (12)
Assembly Manual Safety Bumper SB/BK and SB/W (NO/contact)
Rev.1 140805js
Safety bumpers, regardless of their dimensions and shapes, are based on the same
principle. They consist essentially of the following basic elements:
Normally open contact switch element
Bumper body made of PU soft foam with flexible outer shell
Surface in safety colours, in special cases according to customer requirements or area
of application.
Base mounting via aluminium profiles
Wire connection on aluminium profile
2.2 Product safety information
At rest no pressure must be exerted on the signal transmitter.
Do not twist or bend safety bumper or allow it to sag.
Do not make any holes or recesses in the safety bumper.
Do not cut or trim the safety bumper.
Do not tap or screw any objects into the safety bumper.
Do not use the cable as a carrying handle.
Any manipulation of the bumper body and/or base plate will destroy the safety bumper
and void the warranty.
Use of non-original replacement parts can impair the safety of the safety bumper.
2.3 Applied standards
The design of the product is in conformity with the Machinery Directive 2006/42/EC and EMC
Directive 2004/108/EC.
Applied standards:
•see EC Declaration of Conformity C3002-0
This Installation and Assembly Manual was created based on EN 62079 “Creation of

Type plate
A type plate is attached to the safety bumper for identification purposes. In case of queries,
have the information on the type plate at hand.
4 Transport and storage
4.1 Packaging and transport
Safety bumpers are normally delivered in crush-proof disposable boxes that are reinforced at
the bottom. Additional reinforced packaging is used for longer components. Ensure that
safety bumpers are not exposed to constant pressure or moisture during transport. Do not
stack heavy goods on top of the boxes (not stackable).
When removing the packaging material, make sure not to damage the safety bumpers and
the wiring.
Danger of injury from falling components!
Use only tested load suspension devices that are suitable for the load.
Use appropriate load securing devices (e.g. transport straps, anti-skid devices, etc.).
Do not stand under suspended loads.
4.2 Storage
Store safety bumpers in the original package, in a dry place.
Observe the storage temperature specified in the technical data.

5 Assembly
Before starting with the installation, read this manual in its entirety.
Danger of injury from equipment and components that are located in the vicinity of
the assembly area (electric shock, crushing, etc.)!
De-energise all devices and current-carrying components in the immediate vicinity of the
assembly area and secure against being switched on.
Check again to make sure the devices and/or components are de-energised.
5.1 Prepare assembly area
Prepare subsurface:
•The mounting surface at the installation location should be as flat and stable as
possible to prevent distortion of the safety bumper and therefore premature release.
•Remove dirt particles.
•Cable glands must be deburred
Keep the required tool on hand.
5.2 Unpack
Note the following during unpacking:
Inspect the package for damage.
Material damage due to improper handling
Safety bumpers can be damaged by bending or twisting or by exposure to pointed and/or
sharp objects.
Always take care not to damage the safety bumper during transport.
Place the safety bumper on a level, clean and dry surface.
Do not use the connecting cable of the safety bumper as a carrying handle.

5.3 Assembly
Safety bumpers are pre-assembled and ready for use.
The safety bumpers can be mounted by means of mounting screws and the holes, oval
holes, counterbores, T-grooves, etc. in the base plate.
The mounting materials are not included in the delivery.
Safety bumpers must always be mounted level and free of distortion.
The clearance between the vent holes in the base plate and the nearest surface must be
at least 2.0 mm.
When assembling using threaded bushing (rivets), the thread length of the screw must
not exceed the length of the bushing.
For a safety bumper that is fitted with a standard base plate (T-groove mounting), it is
recommended that the distance between the mounting screws does not exceed 500
mm.
When mounting using threaded bushes, threaded bolts, bores etc. use the specified
positions on the base plate.
The slow-down path of the safety bumper must not be shorter than the maximum braking
path of the moving device (machine, gate, platform or other closing devices).
The slow-down path is the displacement path of the signal transmitter after triggering the
interruption contact until reaching the permissible actuation force, depending on the test
specimen. The slow-down path is specified in the technical data.
5.4 Laying cables
All ends of the connecting cable should be fitted with cable-end sleeves. Optionally plugs or
sockets may be used.
The type of wiring depends on the operating principle of your system.
1. Wire safety bumper cables to each other in accordance with the wiring plan (optional) or
according to the wiring diagrams illustrated under point 5.5. In doing so ensure the
following:
Connect the safety bumper cables to the cable glands.
Connect the safety bumper cables to the cable glands, observing the colour
coding.
Trim the cables if required.
If no plugs or plug sockets (optional) are available, double insulate soldering
points and seal with shrink tubing.
Only extend cables with double-insulated cables with short-circuit protection.

Cables can be damaged if laid incorrectly!
Do not crush or kink cables.
2. Lay cables and route to switch device.

5.5 Check function
Carry out the following steps for each cable of the bumper system:
1. Set the ohmmeter to measure in a high resistance range.
2. Connect the ohmmeter to the two cable conductors.
3. Measure the electrical resistance between the cable glands with activated and non-
activated bumper.
The measured resistance must have the following values:
•Bumper activated: < 150 Ohm
•Bumper not activated:
−Signal transmitter BK: 1 MOhm
−Signal transmitter W: 1k2 ±5% Ohm
Test failed?
If the resistance measurement does not give the required values, this may be caused by the
following:
•The cables of the individual bumpers are not correctly connected
•The cables are kinked or damaged
