    2 Safety Safety In this Chapter Intended Use ..........................5 General Safety Instructions......................5 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.

  • Page 10: Organizational Measures

    Measures for Handling Vacuum­Compatible 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.
