•
Lock the drive shaft on the application side.
•
Push the encoder, with mounted coupling (1), onto the drive shaft and centering
device (2)."Clamp the encoder firmly with the screw (3).
•
Attach the 2 inch encoder with 4 M3 or #6-32 screws (3). Attach the 2.5 inch
encoder with 4 M5 or #10-32 screws.
•
Fix the coupling (1) to the drive shaft. The coupling must not be subject to any
axial stresses.
•
Make the electrical connections with the voltage switched off. Switch on the volt‐
age and check the functioning of the encoder.

•
Lock the drive shaft on the application side.
•
Mount the coupling (1) on the encoder. Take care that it does not touch the
encoder flange.
•
Push the encoder, with mounted coupling (1), onto the drive shaft and centering
device (2).
•
Attach the encoder with either #10-32, #6-32, #4-40 or M4 screws depending on
encoder type (3) and attach the coupling (1) to the drive shaft. The coupling must
not be subjected to any axial stresses.
•
Make the electrical connections with the voltage switched off. Switch on the volt‐
age and check the functioning of the encoder.
