6 Startup and Operation
26 Version: 1.3.0 MP144E N­472 Linear Actuator
NOTICE
Operating frequency too high!
An excessively high operating frequency can cause damage to the N-472.

Operate the N-472 only with controllers/drivers and original accessories from PI.

Do not exceed the operating frequency range (p. 40) specified for the N-472.
NOTICE
Reduced lifetime of the piezo actuator due to permanently high voltage!
Applying a high static voltage to piezo actuators continuously reduces the lifetime of the piezo
ceramic.

When the N-472 is not used, switch off the the controller.
NOTICE
Destruction of the piezo actuator due to electric flashovers!
Using the N-472 in environments that increase the electrical conductivity can lead to the
destruction of the piezo actuator by electric flashovers. Electric flashovers can be caused by
moisture, high humidity, liquids, and conductive materials (e.g., metal dust). In addition,
electric flashovers can also occur in certain air pressure ranges due to the increased
conductivity of the air.

Avoid operating the N-472 in environments that can increase the electrical conductivity.

Only operate the N-472 within the permissible ambient conditions and classifications
(p. 40).

When using in a vacuum under 0.1 hPa:
Do
not
operate the N-472 during evacuating or ventilation.
NOTICE
Friction due to lateral forces!
Lateral forces acting on the fine-threaded screw and the ball tip of the linear actuator increase
the friction on the internal drive components. Increased friction impairs the motion of the fine-
threaded screw and increases wear on the drive components.

Avoid lateral forces on the fine-threaded screw and on the ball tip of the N-472.

Install the N-472 so that the fine-threaded screw is aligned vertically to the contact surface
of the movable part of the mechanical mounting.
