    Safety Intended Use The P-750 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 from dirt, oil, and lubricants. According to its design, the P-750 is intended for fine positioning as well as moving small objects quickly and precisely.

  • Page 6: Safety Precautions

    If the protective earth conductor is not or not properly connected, dangerous touch voltages can occur on the P-750 in the event of malfunction or failure of the system. If there are touch voltages, touching the P-750 can result in minor injury from electric shock.

    P750UM0001, applies to P-750.20 CBo, 1/26/2024 INFORMATION Extension cables can reduce the positioning accuracy of the P-750 or affect sensor processing by the electronics.  Do not use extension cables. If you need longer cables, contact our customer service department (p. 21).

  • Page 11: Mounting The P-750 Onto A Surface

    Mounting the P-750 onto an uneven surface can warp the P-750. Warping reduces the accuracy.  Mount the P-750 onto a flat surface. The recommended flatness of the surface is ≤10 µm.  For applications with large temperature fluctuations: Only mount the P-750 onto surfaces that have the same or similar thermal expansion properties as the P-750 (e.g., surfaces made of steel).

  • Page 13: Fixing The Load

     Mounting the P-750 onto a surface 1. Align the P-750 so that the mounting holes in the P-750 are in line with the mounting holes in the surface. 2. Insert the mounting screws through the countersunk mounting holes in the P-750’s base body into the surface from above.
  • Page 14 If the center of load is located too far away from the center of the motion platform (e.g., tall loads and unwanted lever effect), the P-750 can be damaged by high strain on the flexure guides, high torque, and oscillation, especially when operated dynamically.
