In this Chapter
Intended Use.................................................................................................................................. 5
General Safety Instructions............................................................................................................ 5
2.1 Intended Use
The N-472 is a laboratory device as defined by DIN EN 61010-1. It is intended for indoor use and
use in an environment that is free of dirt, oil and lubricants.
The N-472 is a linear actuator for integration into mechanical and optomechanical components.
For integration, the mechanics, in which the N-472 is to be installed, must have suitable
mountings.
A piezoelectric motor is installed in the N-472 linear actuator that acts on the fine-threaded
screw and moves it.
When at rest, the drive is self-locking and therefore requires no current and generates no heat.
It holds the position with maximum force.
The N-472 is not intended for continuous operation. For further information on the operating
conditions of the N-472, see "Technical Data" (p. 37).
The intended use of the N-472 is only possible in conjunction with a suitable controller (p. 12),
which is available from PI. The controller is not included in the scope of delivery of the N-472.
The controller must provide the required operating voltages. It must also be able to read out
and process the signals from the position sensors so that the servo control system can function
properly.
2.2 General Safety Instructions
The N-472 is built according to state-of-the-art technology and recognized safety standards.
Improper use can result in personal injury and/or damage to the N-472.
Use the N-472 for its intended purpose only, and only when it is in perfect technical
condition.
Read the user manual.
Eliminate any malfunctions that may affect safety immediately.
The operator is responsible for the correct installation and operation of the N-472.

2.2.1 Organizational Measures
User manual
Always keep this user manual together with the N-472.
The latest versions of the user manuals are available for download (p. 3) on our
website.
Add all information from the manufacturer to the user manual, for example
supplements or technical notes.
If you give the N-472 to a third party, include this user manual as well as other relevant
information provided by the manufacturer.
Do the work only if the user manual is complete. Missing information due to an
incomplete user manual can result in minor injury and damage to equipment.
Install and operate the N-472 only after you have read and understood this user
manual.
Personnel qualification
The N-472 may only be installed, started, operated, maintained, and cleaned by authorized and
appropriately qualified personnel.
2.2.2 Measures for Handling Vacuum-Compatible Products
When handling the vacuum version of the linear actuator, attention must be paid to
appropriate cleanliness. At PI, all parts are cleaned before assembly. During assembly and
measurement, powder-free gloves are worn. Afterwards, the linear actuator is cleaned once
again by wiping and shrink-wrapped twice in vacuum-compatible film.
Touch the linear actuator only with powder-free gloves.

3.6 Technical Features
3.6.1 ID Chip
An ID chip is in the D-sub connector (m) of the linear actuator, in which the data on the linear
actuator is stored (e.g., linear actuator type, serial number, date of manufacture, hardware
version).
When switched on or rebooted, controllers from PI read the data from the ID chip.
For more information on the ID chip recognition, see the manual of the controller used.
