Safety
Intended Use
The P-725 focus scanner is a laboratory device as defined by DIN EN 61010-1. It is intended for
indoor use and use in an environment which is free of dirt, oil, and lubricants.
According to its design, the P-725 is intended for positioning and shifting microscope objectives
in one axis.
The P-725 can be mounted horizontally or vertically. The specifications refer to a P-725 with
vertically aligned motion axis.
It is only possible to use the P-725 as intended when it is completely mounted and connected. It
must be operated with a suitable controller that is available from PI (p. 10). The controller is not
included in the scope of delivery of the P-725.
The P-725 may only be started, operated, maintained and cleaned by authorized and qualified
staff.
Safety Precautions
CAUTION
Dangerous voltage and residual charge in piezo actuators!
The P-725 is driven by piezo actuators. Temperature changes and compressive stress can
induce charges in piezo actuators. Piezo actuators can remain charged for several hours after
disconnecting the electronics. Touching or short-circuiting the contacts in the P-725's
connector can lead to minor injuries from electric shock. In addition, the
piezo actuators can be
destroyed by an abrupt contraction.
Do not open the P-725.
Discharge the piezo actuators before installing (p. 19).
Do not pull the connector out of the electronics during operation.
Touching the contacts in the plug connector can lead to an electric shock (max. 120 V DC) and
minor injuries.
Do not touch the contacts in the connector.
Use screws to secure the P-725's connector against being pulled out of the controller.

CAUTION
Risk of electric shock if the protective earth conductor is not connected!
If the protective earth conductor is missing or not properly connected, dangerous touch
voltages can occur on the P-725 in the event of malfunction or failure of the system. If there
are touch voltages, touching the P-725 can result in minor injury due to electric shock.
Connect the P-725 to a protective earth conductor before startup (p. 13).
Do not remove the protective earth conductor during operation.
If the protective earth conductor must be removed temporarily (e.g., for modifications),
reconnect the P-725 to the protective earth conductor before restarting.
NOTICE
On removing the thread adapter, the focus scanner could fall!
The P-725 could fall on removing the upper thread adapter (microscope side) if it is not
secured or screwed on. The thread
adapter and the screwed in objective could fall on removing
the lower thread adapter (objective side).
Secure all parts against falling on removing the thread adapters:
-Screw the objective out before removing.
-Hold the P-725 firmly when you loosen the upper thread adapter.
NOTICE
Unsuitable cables!
Unsuitable cables can damage the electronics.
Only use cables from PI for connecting the P-725 to the electronics.
INFORMATION
Cable extensions can affect the performance of the P-725.
Do not use extension cables. If you need longer cables, contact our customer service
department (p. 23).
