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 four screws using the three fixing
bores of the flange. Consider the depth and diameter of
the thread.
- 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 con-
sumers with high interference emission.
- Encoder case and supply cable have to be completely
screened.
- 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.).
- 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.
Electrical connection
Any outputs not used must not be connected. Unused
cable cores have to be isolated. Max. allowed bending
radius of cable: 90 mm
Connection – MIL-Connector
Whilst not connected, the MIL-plug is always to be sealed
by the plastic cover provided by the manufacturer upon
delivery. Appropriate mating connectors available as spa-
re part or with different cable length, please refer to ac-
cessories. In case of customer-specific length use only
screened cable and connectors corresponding to EMC
standards. Consider the wiring instructions of the respec-
tive supplier.
- Press mating connector softly onto the MIL-plug.
- Turn mating connector carefully until the code-mark is
interlocking the corresponding space provided by the
MIL-plug.
- Insert bushing completely and 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 con-
nector and the nut being secured firmly.

General remarks
Additional information
The installation instruction is supplementary to further
documentation (catalog, data sheet and 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.
Output driver
If the operating voltage is off, do not pulse the outputs
(track) by voltage (danger of destruction).
Provide a terminator at the end of the output connecting
lines, otherwise the output driver might be subject to
overload by line reflections
