6 Version: 1.0.1 PZ254E P­753 Positioning Systems
The P-753 is driven by piezo actuators. Temperature changes and compressive stresses can
induce charges in piezo actuators. After disconnection from the electronics, piezo actuators can
remain charged for several hours. Touching or short-circuiting the contacts in the connector of
the P-753 can lead to minor injuries from electric shock. The piezo actuators can be destroyed
by an abrupt contraction.

Do not open the P-753.

Discharge the positioner's piezo actuators before installation:
Connect the positioner to the switched-off PI controller, which is equipped with an
internal discharge resistor.

Do not pull the plug connector out of the electronics during operation.
Positioners with D-sub plug connector:
Touching the contacts in the plug connector can lead to an electric shock (max. 130 V DC) and
minor injuries.

Do
not
touch the contacts in the plug connector.

Secure the plug connector of the positioner with screws against being pulled out of the
controller.
If a protective earth conductor is not or not properly connected, dangerous touch voltages can
occur on the P-753 in the case of malfunction or failure of the system. If touch voltages exist,
touching the P-753 can result in minor injuries from electric shock.

Connect the P-753 to a protective earth conductor (p. 16) before startup.

Do not remove the protective earth conductor during operation.

If the protective earth conductor has to be removed temporarily (e.g., in the case of
modifications), reconnect the P-753 to the protective earth conductor before starting it
up again.
Mechanical forces can damage or misalign the P-753.

Avoid impacts that affect the P-753.

Do
not
drop the P-753.

Do not exceed the maximum permissible stress and load capacities according to the
specifications (p. 35).

Do not touch any sensitive parts (e.g., motion platform) when handling the P-753.
The P-753 is maintenance-free and achieves its positioning accuracy as a result of the optimum
alignment of mechanical components and piezo actuators. Loosened screws cause a loss in
positioning accuracy.

Loosen screws only when instructed in this manual.

Do
not
open the P-753.
