Screwing on the Piezo Actuator
Tools and Accessories
▪
Electrically conductive surface
▪
Electrically conductive screw
▪
Open-end wrench
▪
Screwdriver or wrench
Requirements
✔
Piezo actuator with stranded wires: The
piezo actuator is discharged and short-
circuited.
✔
The surface has a mounting hole for fixing
the piezo actuator.
✔
The surface is connected to a protective
earth conductor with a cross section of
≥0.75 mm².
Screwing on the Piezo Actuator
1. Secure the base of the piezo actuator with
the open-end wrench.
2. Fix the piezo actuator to the surface by
tightening the screw (see manual for maxi-
mum torque).
Gluing the Piezo Actuator
Tools and Accessories
▪
Electrically conductive surface
▪
Electrically conductive adhesive (e.g.,
silver-filled epoxy resin)
Requirements
✔
Piezo actuator with stranded wires: The
piezo actuator is discharged and short-
circuited.
✔
The glued surfaces were prepared accor-
ding to the specifications of the adhesive
manufacturer.
✔
The surface is connected to a protective
earth conductor with a cross section of
≥0.75 mm².
Gluing the Piezo Actuator
1. Apply the adhesive according to manufac-
turer's instructions.
2. Spread the glue over the entire contact
surface when gluing the piezo actuator.

X
Make sure that the contact resistance at
all protective earth connections is <0.1 Ω
at 25 A.

If ground loops occur, contact the PI custo-
mer service department.

Tools and Accessories
▪
Screw or nut
▪
Open-end wrench
▪
Screwdriver or wrench
Requirements
✔
Piezo actuator with stranded wires: The
piezo actuator is discharged and short-
circuited.
Screwing the Load
1. Secure the tip with the open-end wrench.
2. Tighten the screw or nut (see manual for
maximum torque).
Gluing the Load
Tools and Accessories
▪
Adhesive (e.g., cold-hardening epoxy resin)
Requirements
✔
Piezo actuator with stranded wires: The
piezo actuator is discharged and short-
circuited.
✔
The glued surfaces were prepared accor-
ding to the specifications of the adhesive
manufacturer.
Gluing the Load
1. Apply the adhesive according to manufac-
turer's instructions.
2. Spread the adhesive over the entire contact
surface when gluing the load to the tip.
The instructions required for startup and
operation are in the manual for the electronics
used.
The piezo
actuator must be discharged in the following
cases:
▪
Before short-circuiting
▪
When not in use
▪
Before reconnecting when the connecting
cable was accidentally pulled out of the
electronics during operation
▪
Before assembly work
