2. Safety precautions and operating information

Additional information

• The manual is a supplement to the documentation which already exists (catalogues, product information
and installation manuals).

• It is imperative that the manual is read prior to commissioning.

Proper use

• The encoder is a precision measuring device. It is used exclusively for the detection of angle positions
and rotations, and the processing and provision of the measured values as electrical output signals for
the next device. The encoder may only be used for this purpose.

Commissioning

• The encoder may only be installed and mounted by a qualified electrician.

• Observe the operating manual of the machine manufacturer.

Safety precautions

• Check all electrical connections before commissioning the system.

• If installation, electrical connection or other work on the encoder and on the system are not carried out

properly, malfunction or failure of the encoder may result.

• The endangering of persons, damage to the system and damage to operating equipment due to the
failure or malfunction of the encoder must be prevented with suitable safety measures.

• The encoder may not be operated outside the specified limits (see additional documentation).

Failure to observe the safety precautions can lead to malfunctions, damage and injuries!

Transport and storage

• The encoder may only be transported and stored in the original packaging.

• Do not drop the encoder or subject it to major jolts or impacts.

Assembly

• Avoid impacts or shocks to the housing and shaft.

• Do not torque the housing.

• Do not produce a rigid connection between the encoder and drive shafts.

• Do not open the encoder or modify it mechanically.

The shaft, ball bearings, glass plate or electronic parts can be damaged. Safe operation is then no longer
ensured.

Electrical commissioning

• Do not modify the encoder electrically.

• Do not carry out wiring work while the encoder or system is energized.

• The electrical connection may not be connected or disconnected while energized.

• Install the entire system so that it is EMC-compliant. The installation environment and wiring affect the

EMC of the encoder. Install the encoder and the supply lines in separate locations or at a great distance
from wiring with a high interference level (frequency converters, contactors etc.).

• For consumers with high interference levels, provide a separate power supply for the encoder.

• Complete screen the encoder housing and the connection cables.

• Connect the encoder to protective ground and use shielded cables. The cable shield must be connected

to the screw cable terminal or plug. Connection of the protective ground at both ends, the housing via the
mechanical attachment, and the cable shield via devices connected downstream should be aimed for. If
problems occur with ground loops, grounding should be carried out on at least one end.

Failure to observe the above can lead to malfunctions, damage and injuries!
