Additional information and recommendations
1.2 Intended use
The encoder is a precision measurement device for the acquisition of speed/position in-
formation for the control of drive units and the provision of electronic output signals for
downstream devices.
The encoder must not be used for any other purpose. The function of the encoder is de-
scribed in this mouting instruction. The customer must check the suitability for the purpose
intended.

Do not put encoder into service if there is any visible evidence of damage.
Do not operate encoder beyond the limit values stated in this mounting instruction.
Any risk of personal injury, damage of the system or company equipment due to failure or
malfunction of the encoder has to be eliminated by corresponding safety measures.
Warning
Disregarding intended use could result in serious injury and damage to property.
1.3 Exclusion from liability
The manufacturer is not liable for any damage to persons or property resulting from not
intended use of the encoder.

1.4 Maintenance and lifetime
The encoder may be only opened as described in this instruction. Repair or maintenance
work that requires opening the encoder completely must be carried out by the manufactu-
rer.
Alterations of the device are not permitted.
The expected operating life of the device depends on the ball bearings, which are equipped
with a permanent lubrication.
In the event of queries or subsequent deliveries, the data on the device type label must be
quoted, especially the type designation and the serial number.
1.5 Approvals and warranty
EU Declaration of Conformity meeting to the European Directives.
We grant a 2-year warranty in accordance with the regulations of the Central Association of
the German Electrical Industry (ZVEI).
iwarranty seal
Damaging the warranty seal on the encoder invalidates warranty.
1.6 Storage temperature and disposal
The storage temperature range of the encoder is between -15...+70 °C (caused by pa-
cking).
Encoder components are to be disposed of according to the regulations prevailing in the
respective country.

Risk of serious injuries due to rotating shafts
Hair and clothes may become tangled in rotating shafts. Touching the rotating parts
can cause extremely serious injuries.
» Before all work switch off all operating voltages and ensure machinery is statio-
nary.
» Prevent reconnection operating voltages by third parties.
Risk of serious injuries due to consequential damages
Plants can be deregulated due to malfunction or faulty signals of the encoder.
» Damage caused by faulty operation or by a malfunction of the encoder has to be
eliminated by corresponding safety measures.
Risk of burns due to formation of heat
The encoder heats up at higher speed so there is a serious risk of burning shortly
after the machine has been turned off.
» Examine carefully wether the encoder overheats. Wear suitable gloves if neces-
sary.

2.2 Attention instructions for mounting and operation
)Risk of destruction due to electrostatic charge
Electronic parts contained in the encoder are sensitive to high voltages.
» Do not touch plug contacts or electronic components.
» Protect output terminals against external voltages.
» Do not exceed max. operating voltage.
)Risk of destruction due to mechanical overload
Rigid mounting may give rise to constraining forces.
» Never restrict the freedom of movement of the encoder. The installation instruc-
tions must be followed.

)Risk of destruction due to mechanical shock
Violent shocks, e. g. due to hammer impacts, can lead to the destruction of the
sensing system.
» Never use force. Assembly is simple when correct procedure is followed.
» Use suitable puller for disassembly.
)Risk of destruction due to contamination
Dirt penetrating inside the encoder can cause short circuits and damage the optical
sensing system.
» Absolute cleanliness must be maintained when carrying out any work on the open
terminal box.
» When dismantling, never allow lubricants to penetrate the encoder.

4.1 Mounting the spring disk couling to the encoder
We recommend using the Baumer Hübner spring disk coupling K 35, see section 4.4, page
9, available as accessory. When other couplings are used pay attention to manufactu-
rer‘s notes.
4.2 Mounting to drive shaft
)Lifetime restrictions and angle error by radial deviations
High runout of the drive shaft can cause encoder angle error.
High runout of the drive shaft can cause vibrations, which can shorten the lifetime of
the encoder.

4.4 Maximum permissible mounting tolerance when the Baumer Hübner K 35 spring
disk coupling is used
Encoders should be driven through the Baumer Hübner K 35 spring disk coupling (acces-
sory), that can be pushed onto the shaft without axial loading
)The encoder must be mounted on the drive with the least possible angular error
and parallel misalignment.
)Risk of damaging the ball bearings
Coupling components must not be driven onto the shaft with improper force (e. g.
hammer impacts), because of the risk of damaging the ball bearings.

)Incorrect mounting of the jaw-type coupling can damage the encoder.
Avoid blocking of both coupling halves (claws pressed together). The encoder shaft
