Danger

Warnings of possible danger.

General instructions

Information on appropriate product handling.

General remarks

Additional information 

The installation instruction is supplementary to further  

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 expli-

citly designed for registration of angular positions and 

revolutions as well as evaluation and supply of measu-

ring values as electric output signals for the subsequent-

ly 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, please refer to 

accessories. 

 

-

Use appropriate coupling to link drive shaft and enco-

der shaft. For appropriate links please refer to acces-

sories.

The ends of the shafts must not touch each other. 

Any displacements due to temperature or me-

chanical 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 

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.  

Unused cable cores have to be isolated. 

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 over-

load by line reflections.

Connection – Cable

 

-

Max. bending radius 90 mm. 

Connection – 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 accessories. In 

case of customer-specific length use only screened cable 

and connectors corresponding to EMC standards.

 

-

Turn mating connector carefully until the codemark 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 firmly.
