2.2.2 Safety Measures During Installation
A cable break leads to a failure of the linear actuator.

Install the linear actuator so that the cable is not bent too strongly or crushed during
operation.
Lateral forces that affect the pusher of the linear actuator increase the friction on the internal
drive components. Increased friction impairs the motion of the pusher and increases wear on
the drive components.

Avoid lateral forces on the tip and on the pusher of the M-228 / M-229.
The motion of the pusher can be hindered by a mounting nut that has been tightened too
strongly. This reduces the positioning accuracy.

Do not overtighten the nut (torque ≤15 Nm).
