Please note
Make sure that there is a conductive low−impedance
connection (short cable with large cross−sectional area)
between the CPA−SC valve terminal and the earth potential
(earthed fastening surface or earthed machine stand).
You can thereby avoid faults due to electromagnetic
influences and ensure electromagnetic compatibility in
accordance with EMC guidelines.
