Warning
Sudden unexpected movement of the connected actuators
and uncontrolled movements of loose tubing can cause
injury to human beings or damage to property.
Before carrying out installation and maintenance work,
switch off the following:
the compressed air supply
the operating and load voltage supplies.
Please note
Handle all modules and components of the CPX terminal
with great care. Please note especially the following:
Screw connections must be fitted free of offset and
mechanical tension. Screws must be fitted accurately
(otherwise threads will be damaged).
The specified torques must be observed.
The modules must not be offset (IP65).
Contact surfaces must be clean (avoid leakage and con
tact faults).
The contacts of the Midi/Maxi valve solenoid coils must
not be bent (not resistant to bending, i.e. they will break
off if they are bent back).
Electrostatically sensitive components
Do not touch the contact surfaces of the plug connectors
on the sides of the modules and components.
