About this document
AFS/AFM60 PROFINET Absolut-Encoder are state-of-the-art measuring instruments.
•
The encoder must be installed by trained personnel with knowledge of electrical
engineering and precision engineering.
•
The encoder must only be used for its intended purpose.

Safety information
2.1
Safety advice
CAUTION
•
Observe the professional safety and accident prevention regulations applicable to
your country.
•
Switch off the voltage to all devices/machines and systems affected by the instal‐
lation process.
•
Never electrically connect or disconnect the encoder with the voltage switched on,
this may lead to damage to the unit.
•
Avoid striking the shaft or collet.

Electrical installation
3.1
Shielding acc. to interface specification
We recommend the use of shielded cables with the shield connected at both ends. To
achieve optimum screening effectiveness and to prevent mass equalisation currents
from flowing across the screen, note the following:
•
It must be ensured that there is a good electrical connection between the metal
housing of the encoder and the earthed metal parts of the system/machine. This
is usually achieved by the metallic connection across the encoder flange.
•
If the fixing method used does not have a well-conducting electrical connection,
additional measures in the form of an earthing cable must be taken.
3.2
Connection to the network (Port 1 or Port 2)
•
Direct connection via M12 screw-in system.
•
On delivery, Port 2 is provided with a screw-on plastic cap.
Tightening torque 0.4 Nm
•
Enclosure rating IP65 (shaft), IP67 (housing) is only achieved when plugs or plastic
caps are screwed on.
3.3
Installation notes: voltage supply
The supply voltage is generally supplied via a separate line and is not designed as a
line structure. If, for the voltage supply, the same cabling arrangement as used by the
bus is implemented, the following limitation applies:
CAUTION
Max. current flow across the plugs or terminal block in the bus link adapter is limited to
2 A.
