Potential equalization
The valve terminal has two earth connections for potential
equalization.
–
on the load voltage connection (pin 4 incoming socket).
–
on the left-hand end plate (M4 thread).
Please note
S
Always connect the earth potential to pin 4 of the volt-
age connection.
S
Connect the earth connection of the left-hand end plate
to the earth potential with low impedance (short cable
with large cross-sectional area).
S
By means of low-impedance connections, you can be
sure that the housing of the valve terminal and the earth
connection at pin 4 have the same potential and that
there are no equalizingcurrents.
You can thereby avoid interference due to electromagnetic
influences and you can ensure electromagnetic compatibil-
ity in accordance with the EMC guidelines.
