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.

Assembly Instructions

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

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.

Electrical Connection

Any outputs not used must not be connected.

Connection – M23-Connector

Whilst not connected, the connector is always to be

sealed by the plastic cover provided by the manufacturer

upon delivery. Appropriate mating connectors available as

spare part or with different cable length, please refer to

accessories. In case of customer-specific length use on-

ly screened cable and connectors corresponding to EMC

standards. Consider the wiring instructions of the respec-

tive supplier.

Press mating connector softly onto the connector.

Turn mating connector carefully until the code-mark is

interlocking the corresponding space provided by the

connector.

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.
