The CPV valve terminal has its own earthing/ground connec
tion on the left−hand end plate.
Please note
S Connect the earth/ground connection of the left−hand
end plate with low impedance (short cable with large
cross−sectional area) to the earth potential.
You will thereby avoid interference as a result of electro−
magnetic influences.
Example of connection
Observe the following when connecting the 24V load voltage
supply (pin 2):
The tolerance 21 V ... 26.4 V DC must be observed.
S
Use a cable with sufficient cross−sectional area to connect
S
the earth connection on the CPV valve terminal.
