Safety
Intended Use
The P-725 scanner 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-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 vertically
mounted P-725.
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. After
disconnecting from the electronics, piezo actuators can
remain charged for several hours. Touching or short-circuiting the contacts in the connector of
the P-725 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. 28).
Do not pull the connector out of the electronics while it is operating.
For P-725 with D-sub connector:
Touching the contacts in the plug connector could lead to an electric shock (max. 120 V DC)
and minor injuries.
Do not touch the contacts in the plug 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 has to be removed temporarily (e.g., for modification),
reconnect the P-725 to the protective earth conductor before restarting.
NOTICE
Falling down when removing the thread adapters!
The P-725 could fall down while removing the upper thread adapter (microscope side) if it is
not secured or tightly screwed. The thread adapter and the objective screwed in could fall
down while removing the lower thread adapter (objective side).
Secure all parts against falling down while 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 cause damage to 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. 30).

Requirements
You have read and understood the safety precautions (p. 6).
The P-725 is not connected to the electronics.
Tools and accessories
Suitable protective earth conductor: Cable cross section ≥ 0.75 mm2
M4 protective earth conductor screw set for connecting the protective earth conductor
(p. 10)
Suitable screwdriver
Connecting the P-725 to the protective earth conductor
1. If necessary, attach a suitable cable lug to the protective earth conductor.
2. Use the M4 screw (together with the flat and lock washers) to fix the cable lug of the
protective earth conductor to the protective earth connector of the P-725 as shown in
the profile view.
3. Tighten the M4 screw with a torque of 1.2 Nm to 1.5 Nm.
4. Make sure that the contact resistance at all points relevant for attaching the protective
earth conductor is <0.1 Ω at 25 A.
Mounting the P-725 with Thread Adapters to the Microscope (Depending
on Model)
The PIFOC objective positioners are inserted with thread adapters between the microscope's
revolving nosepiece and objective (p. 11). In addition, it is possible to mount the P-725 base
body via the mounting holes (p. 24).

3. Screw the thread adapter on the microscope side into the microscope.
4. Tighten the thread adapter on the microscope side with the narrow side of the key tool.
5. Make sure that the thread adapter's spring washer on the microscope side is neither
too tight nor loose. If necessary, set the tension of the spring washer by turning the
clamping ring. Only unscrew the clamping ring as far as necessary.
6. Push the PIFOC positioner slowly into the thread adapter on the microscope side until it
snaps in completely.
7. Insert the tightening tool into one of the holes in the clamping ring for the thread
adapter on the microscope side and lightly tighten the ring. The clamping ring will be
visible through the slot in the PIFOC positioner. Make sure the clamping tool is well
seated before applying any pressure.
8. Align the PIFOC positioner as required.
9. Tighten the clamping ring for the thread adapter on the microscope side with the
tightening tool.
