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-thread 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. 39).
The intended use of the N-472 is only possible in conjunction with a suitable controller (p. 13),
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.
Only use the N-472 for its intended purpose, and only use it if it is in a good working
order.
Read the user manual.
Immediately eliminate any faults and malfunctions that are likely to affect safety.
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 available 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 other users, also include this user manual as well as other
relevant information provided by the manufacturer.
Only use the device on the basis of the complete user manual. Missing information due
to an incomplete user manual can result in minor injury and damage to equipment.
Only install and operate the N-472 after you have read and understood this user
manual.
Personnel qualification
The N-472 may only be installed, started up, 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.
Only touch the linear actuator with powder-free gloves.

ID chip
An ID chip is in the sensor connector 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.

4 Unpacking
N-472 Linear Drive MP144E Version: 1.0.0 15
INFORMATION
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 is then shrink-wrapped twice in vacuum-compatible film.
Only touch the linear actuator with powder-free gloves.
1. Unpack the N-472 with care.
2. Compare the contents with the items listed in the contract and the packing list.
3. Inspect the contents for signs of damage. If parts are missing or you notice signs of
damage, contact PI immediately.
4. Keep all packaging materials in case the product needs to be returned.
