General Notes on Installation
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.
NOTICE
Increased wear due to friction!
Increased friction on the contact surface between the ball tip and the movable part of the
mechanical mounting increases wear.
Make sure that the contact surface of the mechanical mounting has a roughness of R
a
<0.1 µm and a hardness of at least 500 HV (corresponds to hardened steel).
Optional: Decrease the friction by applying a small amount of lubricant to the contact
surface of the mechanical mounting.
NOTICE
Heating up of the N472 during operation!
During operation, the N-472 emits up to 5.2 watts of heat that can affect your application.
Install the N-472 so that your application is not affected by the dissipating heat.
Ensure sufficient ventilation at the place of installation.
Pay attention to the operating conditions (duty cycle, ambient temperature) according to
the specifications in "Technical Data" (p. 37).
