Danger
Warnings of possible danger.
General instructions
Information on appropriate product handling.
General remarks
Additional information
The installation instruction is supplementary to already
existing 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.

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
Avoid punches or shocks on case and shaft.
-
Avoid case distortion.
-
Do not use any rigid links between encoder shaft and
-
drive shaft.
Do not open or modify encoder in any mechanical way.
-
Shaft, bearing, glass disc or electronic componen-
ts might be damaged and a secure operation is no
longer guaranteed.
Mechanical assembly
Mount encoder using three screws using the three
-
fixing bores of the flange. Consider the depth and dia-
meter of the thread.
Alternative mounting in any angular position is possible
-
by means of three eccentric fixings (accessories).
Use appropriate coupling to link drive shaft and encoder
-
shaft. For appropriate links please refer to accessories.
The ends of the shafts must not touch each
other. Any displacements due to temperature or
mechanical tolerances have to be equalized by the
coupling. Mind the maximum permitted axial or
radial shaft load. Tighten fixing screws firmly.

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
-
consumers 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 disregard may lead to malfunctions, material damage
and personal injury.
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 connector and the nut being
secured firmly.
Exchange bus cover
The bus cover is to be stored and transported whilst in
the ESD bag only. The bus cover has to fit the case tightly
and has to be firmly secured by screws.
Remove bus cover
Unscrew both fixing screws of the bus cover.
-
Loosen bus cover carefully and remove it in axial direc-
-
tion.
Plug on bus cover
Plug the bus cover carefully onto the D-SUB plug of the
-
basic encoder, then push it over the rubber seal. Avoid
the case getting wedged. The bus cover has to fit tightly
the basic encoder.
Tighten both fixing screws firmly and conformable.
-
An optimized connection between encoder case and
-
the braiding shield of the supply cable is only achieved
by a complete and close fit of the bus cover onto the
basic encoder (interlock).
Assignment – M12 connector
Follow also the instructions of the respective supplier.
Press mating connector softly into the plug.
-
Turn mating connector carefully until the code mark is
-
interlocking the corresponding space provided by the
plug. Insert bushing completely. Tighten the nut as far
as possible.
