Assembly Instructions GB
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 qualifi ed 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.
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 fi xing and
clamp ring screws fi rmly.
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 -
braided 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 electrically isolated a second connection has to be
provided. Ground cable screen by the subsequently
connected devices.
In case of ground loop problems at least grounding on -
one side is imperative.
Any disregard may lead to malfunctions, material damage
and personal injury.

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.
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 fi rmly.

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.
Hollow 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-fi t f7) and
tighten clamping ring fi rmly.
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 fi xing holes provided on housing by means of screws.
Slide encoder onto the drive shaft and fasten spring coupling at the surface provided
with screws.

Exchange bus cover
The bus cover is to be stored and transported whilst in
the ESD bag only. The bus cover has to fi t the case tightly
and has to be fi rmly secured by screws.
Remove bus cover
Unscrew both fi xing screws of the bus cover. -
Loosen both bus cover elements carefully and remove it in -
axial direction.
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 fi t tightly
the basic encoder.
Tighten both fi xing screws fi rmly and conformable. -
An optimized connection between encoder case and -
the braiding shield of the supply cable is only achieved
by a complete and close fi t of the bus cover onto the
basic encoder (interlock).
