Danger
Warnings of possible danger.
General instructions
Information on appropriate product handling.
General remarks
Additional information
The installation instruction is supplementary to further
documentation (e.g. catalog, data sheet, manual).
It is imperative to read the manual carefully prior to star-
ting the device.
Appropriate use
- The encoder is a precision measuring device. It is ex-
plicitly designed for registration of angular positions
and revolutions as well as evaluation and supply of
measuring values as electric output signals for the sub-
sequently connected device. The encoder must not be
used for any other purpose.
Start up
- Installation and assembly of the encoder only by electri-
cally skilled and qualified personnel.
- Consider also the operation manual of the machine
manufacturer.
Safety instructions
- All electrical connections are to be revised prior to star-
ting the system.
- Incorrect assembly and electrical connections or any
other inappropriate work at encoder and system may
lead to malfunction or failure of the encoder.
- 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.
- Do not operate encoder beyond the limit values stated
in the data sheet.
Any disregard may lead to malfunctions, material damage
and personal injury.

Electrical installation
- Do not modify encoder in any electrical way and carry
out any wiring work under power supply.
- Any electrical connection and plugging-on whilst under
power supply is not permitted.
- A separate encoder supply has to be provided with con-
sumers with high interference emission.
- Installation of the whole system has to be according
to EMC standards. Installation environment as well as
wiring have an impact on the encoder’s EMC. Encoder
and supplying lines are to be in separated locations or
remote from lines with high interference emission (fre-
quency transformers, protections, etc.).
- Encoder case and supply cable have to be completely
screened.
- Ground (PE) encoder by using screened cables. The brai-
ded shield has to be connected to cable gland or plug.
Grounding (PE) on both sides is recommended.Ground
the case by the mechanical assembly, if latter is electri-
cally isolated a second connection has to be provided.
Ground cable screen by the subsequently connected
devices. In case of ground loop problems at least groun-
ding on one side is imperative.
- Any outputs not used must not be connected. Unused
cable cores have to be isolated. Max. allowed bending
radius of cable: 90 mm
Any disregard may lead to malfunctions, material damage
and personal injury.
Assignment – M23-Connector
Whilst not connected, the plug is always to be sealed by
the plastic cover provided by the manufacturer upon de-
livery. Appropriate mating connectors available as spare
part or with different cable length, please refer to acces-
sories. In case of customer-specific length use only scree-
ned cable and connectors corresponding to EMC stan-
dards. Consider the wiring instructions of the respective
supplier.
- Press mating connector softly onto the plug.
- Turn mating connector until the code-mark is interlo-
cking the corresponding space provided by plug.
- Insert bushing completely.
- Tighten the nut as far as possible.
All movable adjusting elements need tolerance in both
axial and radial direction in order to equalize shifts by tem-
perature and of mechanical nature. Tighten both fixing and
clamping ring screws firmly.

An optimized connection between encoder case and the
braided shield of the connection cable is only achieved by
the braided shield being placed generously onto the con-
nector and the nut being secured firmly. Please use cores
twisted in pairs (for example clock+/clock-) for extension
cables of more than 10 m length.

Disposal
Encoder components are to be disposed of according to
the regulations prevailing in the respective country.
Transport and storing
- In original packing only.
- Do not drop or expose encoder to major shocks.
Assembly
- Open clamping ring completely before mounting the
encoder.
- Avoid punches or shocks on case and shaft.
- Avoid case distortion.
- Do not open or modify encoder in any mechanical way.
- The spring arm of the spring coupling has to be free
movable.
Holow shaft, bearing, glass disc or electronic
components might be damaged and a secure
operation is no longer guaranteed.
Hollow shaft mounting
Mounting with clamping ring
Plug encoder completely onto drive shaft (ISO-fit f7) and
tighten clamping ring firmly (max. 1.2 Nm).
Depth of im-
mersion 35 mm.
Mechanical assembly
Slide encoder onto the drive shaft and insert torque pin
into the adjusting element provided by customer or
insert pin into the mounted adusting part (with rubber
spring element) provided by customer.
Spring coupling
Fasten spring coupling at the fixing holes provided on housing by means of screws.
Slide encoder onto the drive shaft and fasten spring coupling at the surface provided
with screws.
