2.2 General Safety Instructions
The P-611 is built according to state-of-the-art technology and recognized safety standards.
Improper use can result in personal injury and/or damage to the P-611.

Use the P-611 for its intended purpose only, and only when it is in perfect technical
condition.

Read the user manual.

Eliminate any malfunctions that may affect safety immediately.
The operator is responsible for the correct installation and operation of the P-611.
The P-611 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 connector in the
P-611 can lead to minor injuries from electric shock. The piezo actuators can be destroyed by an
abrupt contraction.

Do not open the P-611.

Discharge the positioner's piezo actuators before installing:
Connect the positioner to the switched-off PI electronics 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.

Use screws to secure the positioner's connector against being pulled out of the
electronics.
If a protective earth conductor is not or not properly connected, dangerous touch voltages can
occur on the P-611 in the case of malfunction or failure of the system. If there are touch
voltages, touching the P-611 can result in minor injuries from electric shock.

Connect the P-611 to a protective earth conductor (p. 18) before starting.

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-611 to the protective earth conductor before restarting.
