3 Safety
3.1 Intended Use
The P-841 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.
In accordance with its design, the P-841 is intended for the following applications:
■Positioning of loads; see "Specifications" (p. 28)
■Dynamic positioning
■Vibration absorption
■Force generation
Motion is along one axis.
The P-841 is not intended for applications in areas where failure would result in considerable
risks for human beings or the environment.
The intended use of the P-841 is only possible when completely mounted and connected.
The P-841 must be operated with suitable electronics (p. 11) from PI. The electronics are not
in the scope of delivery of the P-841.
The P-841 may not be used for purposes other than those stated in this user manual. The
P-841 may only be used in compliance with the technical specifications and instructions in
this user manual.
3.2 General Safety Instructions
Temperature changes and compressive stress can induce charges in the P-841 piezo actuator.
After disconnection from the electronics, the piezo actuator can remain charged for several
hours. Touching live parts of the P-841 can result in minor injury from electric shock.
►Do not open the P-841.
If the protective earth conductor is missing or not properly connected, risk of dangerous
touch voltages on the P-841 in the event of malfunction or failure of the system. If touch
voltages exist, touching the P-841 can lead to minor injury from electric shock.
►Connect the P-841 to a protective earth conductor before startup.
►Do not remove the protective earth conductor during operation.
►If the protective earth conductor has to be temporarily removed (e.g., for modifications),
reconnect the P-841 to the protective earth conductor before restarting.
Mechanical forces can destroy the P-841.
►Avoid knocks that affect the P-841.
►Do not drop the P-841.
►Avoid torques, bending forces, and lateral forces on the tip of the P-841.
►Do not exceed the maximum permissible loads (p. 28).
The P-841 is built according to state-of-the-art technology and recognized safety standards.
Improper use of the P-841 may result in personal injury and/or damage to the P-841.
►Use the P-841 only for its intended purpose and when it is in perfect condition.
►Read the user manual.
►Eliminate any malfunctions that may affect safety immediately.
The operator is responsible for installing and operating the P-841 correctly.

3.3.1 User Manual
►Always keep this user manual available with the P-841. The latest versions of the user
manuals can be downloaded (p. 7) at www.pi.ws.
►Add all information from the manufacturer such as supplements or technical notes to the
user manual.
►If you give the P-841 to a third party, 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 P-841 after you have read and understood this user manual.
3.3.2 General Personnel Qualification
The P-841 may only be installed, started up, operated, maintained, and cleaned by authorized
and appropriately qualified personnel.
