Note
Always connect the earth potential to pin 4 of the power
·
supply connection.
Connect the earth connection of the end plate with low
·
impedance (short cable with large cross−sectional area)
to the earth potential.
By means of low−impedance connections, make sure
·
that the housing of the valve terminal and the earth con
nection at pin 4 have the same potential and that there
are no equalizing currents.
In this way, you will avoid interference caused by electro
magnetic influences.
