Switch off the compressed air supply
•
Vent the valve terminal
Before working on the electrical components, e.g. before
installation or maintenance work:

Switch off the power supply
In this way, you can avoid:
– uncontrolled mo vements of loose tubing
– unexpected and uncontrolled movements of the co nnec-

Observe the handling specifications for electrostatically
sensitive devices.
This will help to prevent damage to the electroni cs.
