APF503, APF705 and APF710 Amplified Flexure Piezo Actuators
Chapter 3 Installation

3.1 Storage Precautions

Warning
Piezos can store and release large amounts of energy and should be handled
with caution. To prevent charge build up, piezos must be stored with the high
voltage wires (red and white) joined together (short circuit).

3.2 Mechanical Installation

Caution
When removed from its packaging, the piezo assembly is easily damaged by
mishandling. In particular, do not squeeze the assembly, or apply compression
to the mechanical flexure. Doing so could cause the piezo to become detached
from the mechanical amplifier assembly.
The APF series actuators have an open frame design, intended for incorporation into
other third party equipment, and installation will depend on the specific application.
Therefore, undertaking necessary assessments related to the use of the actuator in
an assembly remains the responsibility of the end user. Detailed dimensional
information is contained in the drawings available from www.thorlabs.com.
