VIII Festo CPX-FB36-EN en 1611a English
Intended use
The bus node described in this description is intended exclus
ively for use in CPX terminals from Festo for installation in a
machine or automated system.
In combination with a CPX terminal, the bus node is used for
communication as a participant in networks with the proto
cols EtherNet/IP or ModbusTCP.
The CPX terminal may only be used as follows:
– as intended in industrial environments; outside of indus
trial environments, e.g. in commercial and mixed-residen
tial areas, actions to suppress radio interference may
have to be taken
– in its original state without unauthorised modifications;
only the conversions or modifications described in the
documentation supplied with the product are permitted.
– in perfect technical condition
– only in combination with approved components
Observe the specified limit values.
Take into consideration the applicable regulations for the
destination as well as directives and standards, regula
tions of the inspection organisations, insurance compan
ies and national regulations.

Safety instructions
Before assembly or installation work, switch off the power
supply, switch off the compressed air supply, exhaust any
pneumatic components.
For the electrical power supply, only use PELV circuits in
accordance with IEC 60204-1/EN 60204-1.
Note the information on installation and power supply as
well as on potential equalisation (earthing measures) in
the CPX system description (èP.BE-CPX-SYS-…).
Observe the handling specifications for electrostatically
sensitive devices.
Seal unused connections with cover caps to achieve the
required degree of protection.
Use connection technology with the required degree of
protection.
Observe the specifications in the CPX system description,
in the descriptions of the valve terminal used as well as in
the assembly instructions of the individual components.
Observe the instructions for correctly mounting the CPX
terminal.
Place only a completely mounted and wired CPX terminal
into operation.
Only switch on the compressed air and load voltage if the
system has been professionally installed, configured and
parameterised.
Make sure that nobody enters the positioning range of
the actuators.
Switching off the compressed air or load voltage is not a suit
able locking mechanism. Unintentional movement of actuat
ors may occur in the event of a malfunction.
