Please note
Handle all modules and components of the CPX terminal
with great care. Please note especially the following:
Screws must be fitted accurately (otherwise threads will
•
be damaged).
Screws must be tightened only by hand. Place screws so
that the self-cutting threads can be used.
The specified torques must be observed.
•
Screw connections must be fitted free of offset and
•
mechanical tension.
Check the seals for damage (IP65).
•
Connecting surfaces must be clean (sealing effect, avoid
•
leakage and contact faults).
The screw connection between the sub-base and the mani-
fold is designed for at least 10 fitting/removal cycles under
observance of the instructions.
Observe also the installation instructions supplied with
modules and components ordered at a later stage.
CPX terminals are supplied from the factory completely fitted.
It may be necessary to fit or remove the sub-bases for the
following reasons:
– for replacing the connections.
– to simplify fitting the sensor plugs or cables.
It may be necessary to fit or remove the electronic modules
for the following reasons:
– for modifying the function of the I/O module (e.g.
CPX-8DE instead of CPX-4DE).
– for replacing defective electronic modules.
