All screw connections must be secured against loosening with liquid screw
adhesive (LOCTITE 243, for example).
NOTICE
Spring washers and toothed washers are not sufficient for securing
screws.
•
All mounting surfaces should have a contact surface pressure > 200 N/
mm².
•
For variants with a stator coupling, the entire stator coupling must lie flat on
the mounting surface.
•
All fixing screws should not exceed a screw-in depth of 5 threads.
For variants with a stator coupling, it may not be possible to hold the torque
wrench perpendicular to the screw. An angle of inclination of up to 20° is included
in the tightening torque tolerance. Loosening or securing the screw at an angle on
a regular basis can cause damage to the screw (see
and
).
NOTICE
The encoder must not be mounted with double elasticity (either stator or
shaft coupling).
If the connections are form-fit, ensure that the parts to be mounted are free of
lubricants and contaminations.

Pre-installation steps
If necessary, mount the feather key on the drive shaft provided by the cus‐
tomer.
A feather key must be used for drive shafts with a diameter of 6 mm, 8 mm,
and 3/8”. This ensures the over-dimensioning required to rule out errors
caused by the shaft connection.
Mounting
1.
Apply screw adhesive (observe
) to the thread of the clamping ring
or the supplied T20 Torx screw.
2.
Insert the T20 Torx screw in the clamping ring and secure it loosely; do not
tighten it at this stage.
3.
Push the encoder onto the drive shaft provided by the customer, aligning it
with the feather key, if in use.
4.
Secure the screws and the washers loosely and apply screw adhesive
) to the threads.
5.
Screw in the screws until the encoder can be fully pushed on and the stator
coupling is resting against the mounting surface.
6.
Align and block the drive shaft provided by the customer in line with the
mounting conditions, i.e. the accessibility of the screw.
7.
Tighten the screw; tightening torque: 1.2 ± 0.1 Nm.
8.
Tighten the T20 Torx screw on the clamping ring, tightening torque:
3.5 ± 0.1 Nm.
