1 Safety and operating instructions
1.1
Supplementary information
This manual is intended as a supplement to already existing documentation (catalogues, data sheets and
assembly instructions).
The manual must be read without fail before initial commissioning of the equipment.
1.2
Intended purpose of the equipment
The encoder is a precision measuring device. It is explicitly designed for registration of angular positions and
revolutions as well as evaluation and supply of measuring values as electric output signals for the subsequently
connected device. The encoder must not be used for any other purpose.
1.3
Commissioning
Installation and assembly of the encoder only by electrically skilled and qualified personnel.
Consider also the operation manual of the machine manufacturer..
1.4
Safety remarks
Prior to commissioning the equipment, check all electrical connections.
If installation, electrical connection or any other work performed at the encoder or at the equipment is not
correctly executed, this can result in a malfunction or failure of the encoder.
Steps must be taken to exclude any risk of personal injury, damage to the plant or to the operating equipment
as a result of encoder failure or malfunction by providing suitable safety precautions.
Encoders must not be operated outside the specified limited values (see detailed product documentation).
Failure to comply with the safety remarks can result in malfunctions, personal injury or damage to property.
1.5
Transport and storage
Only ever transport or store encoders in their original packaging.
Never drop encoders or expose them to major vibrations.
1.6
Assembly
Avoid impacts or shocks on the housing and shaft / hollow shaft.
Avoid any twist or torsion on the housing.
Do not open the encoder or make any mechanical changes to it.
The shaft, ball bearings, glass pane or electronic components can be damaged. In this case, safe and reliable operation
cannot be guaranteed.
1.7
Electrical commissioning
Do not modify the encoder electrically and remove power supply while connecting the encoder electrically.
The electrical connection must not be attached or removed under power supply.
Only use shielded cables. The cable shield must be attached over a large area with as less impedance as
possible. EMC-compatible connectors and cable bushings must be used for connecting the encoder to a control
system.
Ensure that the entire plant is installed in line with EMC requirements. The installation environment and wiring
affect the electromagnetic compatibility of the encoder. Install the encoder and supply cables separately or at a
long distance from cables with high interference emissions (frequency converters, contactors etc.)
Where working with consumers which have high interference emissions, make available a separate power
supply for the encoder.
The encoder housing must be grounded via the encoder flange, if the mechanical structure is electrically
isolated an additional grounding must be provided.
The protective earth (PE) should be attached to both sides, the mechanical structure and the control system in a
way to avoid impedance. In order to prevent currents in the cable shielding, a potential equalization should be
implemented.
When a potential ground loop can't be avoided, only one side must be grounded.
Unused outputs must not be connected.
Failure to observe these instructions can result in malfunctions, material damage or personal injury.
