General Notes on Maintenance 

The P-2x5 is maintenance-free. 

 

7.2

 

Cleaning the P-2x5 

 

NOTICE 

 

Destruction of the piezo actuator by electric flashovers! 

The intrusion of fluids into the case of the piezo actuator can lead to the destruction of the 

piezo actuator by electric flashovers. 

Before cleaning the P-2x5: 
1.

 

Discharge the P-2x5 (p. 34). 

2.

 

Disconnect the voltage connection of the P-2x5 from the electronics. 

3.

 

Connect the voltage connection of the P-2x5 with the supplied shorting plug (p. 17). 

  

 

NOTICE 

 

Damage from ultrasonic cleaning! 

Ultrasonic cleaning can damage the P-2x5. 

 

Do 

not

 do any ultrasonic cleaning. 

  

Requirements 

 

The P-2x5 is 

not

 connected to the electronics. 

 

The P-2x5 is discharged (p. 34) and short-circuited by the shorting plug (p. 12) provided.
