In this Chapter
Intended Use.................................................................................................................................. 5
General Safety Instructions............................................................................................................ 5
2.1 Intended Use
The N-470 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-470 is a linear actuator for integration into mechanical and optomechanical components.
For integration, the mechanics, in which the N-470 is to be installed, must have suitable
mountings.
A piezoelectric motor is installed in the N-470 linear actuator that acts on the fine-threaded
screw and moves it.
The drive is self-locking at rest, requires no current, and does not generate any heat. It holds
the position with maximum force.
The N-470 is not intended for continuous operation. For further information on the operating
conditions of the N-470, see "Technical Data" (p. 35).
It is only possible to use the N-470 as intended in conjunction with suitable electronics (p. 14)
that provide the required operating voltages. The electronics are not in the scope of delivery of
the N-470.
2.2 General Safety Instructions
The N-470 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-470.
Use the N-470 for its intended purpose only, and only when it is in perfect technical
condition.
Read the user manual.
Eliminate any faults and malfunctions likely to affect safety immediately.
The operator is responsible for the correct installation and operation of the N-470.

2.2.1 Organizational Measures
User manual
Always keep this user manual available with the N-470.
The latest versions of the user manuals are available for download (p. 2) on our
website.
Add all information from the manufacturer to the user manual, for example
supplements or technical notes.
If you give the N-470 to other users, also include this user manual as well as other
relevant information provided by the manufacturer.
Use the device 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-470 only after you have read and understood this user
manual.
Personnel qualification
The N-470 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.
Touch the linear actuator only with powder-free gloves.
