CAUTION
Risk of electric shock if the protective earth conductor is not connected!
If the protective earth conductor is missing or not properly connected, risk of dangerous
touch voltages on the P-844 in the event of malfunction or failure of the system. If touch
voltages exist, touching the P-844 can lead to minor injury from electric shock.
►
Connect the P-844 to a protective earth conductor before startup.
►
Do not remove the protective earth conductor during operation.
►
If the protective earth conductor has to be temporarily removed (e.g., for modifications),
reconnect the P-844 to the protective earth conductor before restarting.
Information
The P-844 can heat up during operation. The heat produced during operation can affect your
application.
Mounting the P-844
1. Use an open-end wrench to hold the base of the P-844 in position.
2. Screw the P-844 onto a suitable underlying surface. For this purpose, screw into the
mounting hole in the bottom of the base (p. 29)
.
3. Remove the open-end wrench from the base.

NOTICE
Destruction of the piezo actuator due to mechanical overload!
Torques, bending and lateral forces, tensile stress, and excessive loads can destroy the piezo
actuator.
►
Do not exceed the maximum permissible loads according to the
.
►
Avoid torques, bending forces and lateral forces on the tip of the piezo actuator.
►
Avoid torques on the base when the tip is tightly clamped.
►
Make sure that the center of load of the moving system is on the motion axis of the piezo
actuator.
►
Use suitable structures or guide elements (e.g., ball tips or flexure guides) to avoid
uneven load distribution.
►
Pay attention to the information on parallelism in the
.
►
Do not screw the piezo actuator tight at both ends.
