5 Installation
M­­228 / M­­229 Linear Actuators MP86E Version: 2.0.0 21

Take into account the following specifications as well when planning the application
and installing the actuator:
−
Dimensions of the selected tip (see "Dimensions" (p. 38))
− Travel range: Maximum 10 mm (M-228) or 25 mm (M-229)
−
Space requirements for bend-free and proper guiding of the connecting cable and if
applicable, additional cables
− Length of the connecting cable and if applicable, additional cables
− Position of the actuator position indicator, if it is to be read during operation

If the limit switches of the actuator cannot be reached with the planned minimum and
maximum displacements: Make sure that the actuator and the load only move within
the planned range . Suitable measures:
− Corresponding programming of the controller
− Emergency off switch
− Automatic shutdown systems

In accordance with the legal regulations, avoid or label danger areas resulting from the
installation of the actuator and from use (e.g., risk of crushing in the case of heavy
moving loads, fast actuator motion and/or high drive torques).
You can obtain all dimensions of the actuator and relevant individual parts in the section
"Dimensions" (p. 38).
5.4 Installing the M­228 / M­229 in a Mechanical Mounting
NOTICE
Incorrect tightening torque of the mounting nut!
The motion of the pusher can be hindered by a mounting nut that has been tightened too
strongly. This reduces the positioning accuracy.

Tighten the mounting nut to a maximum torque of 15 Nm.
INFORMATION
To achieve an optimal repeatability, the mounting shaft must not have any backlash.

When assembling, make sure that the actuator and the mechanical mounting have been
connected perfectly.
