Intended use
The field bus node type CPX−FB38 described in this manual
has been designed exclusively for use as a slave (I/O device
or Box") in an EtherCAT network.
The CPX terminal must only be used as follows:
asdesignated in industrial applications
inoriginal condition without modification (only the con
versions or modifications described in the documentation
supplied with the product are permitted).
infaultless technical condition.
The maximum values specified for pressures, temperatures,
electrical data, torques etc. must be observed.
If additional commercially available components such as
sensors and actuators are connected, the specified limits for
pressures, temperatures, electrical data, torques, etc. must
not be exceeded.
Also observe the standards specified in the relevant chapters,
as well as national and local laws and technical regulations.
Warning
·In order to provide the electric power supply, use only
PELV circuits as per IEC/DIN EN 60204−1 (Protective
Extra−Low Voltage, PELV).
Take into account also the general requirements for PELV
circuits as per IEC/DIN EN 60204−1.
·Use only power packs which guarantee reliable electrical
isolation of the operating voltage as per IEC/DIN
EN60204−1.

Contents and general instructions
VIII Festo P.BE−CPX−FB38−EN en 0804NH
Protection against electric shock (protection against direct
and indirect contact) is ensured in accordance with IEC/DIN
EN 60204−1 (electrical equipment of machines, general
requirements) by using PELV circuits.
If implementing an emergency stop function, note the
measures listed in the sections 2.5.1, 2.8 and 3.1.
Target group
This manual is intended exclusively for technicians trained in
control and automation technology, who have experience in
installing, commissioning, programming and diagnosing
programmable logic controllers (PLC) and Fieldbus systems.
Service
Please consult your local Festo repair service if you have any
technical problems.

Warning
Switch off the following equipment before undertaking
installation and/or maintenance work:
 the compressed air supply
 the operating voltage supply for the electronics/sensors
 the load voltage supply for the outputs/valves.
You can thereby avoid:
 uncontrolled movements of loose tubing.
 unexpected movements of the connected actuators.
 non−defined switching states of the electronic
components.
Caution
The CPX bus node contains electrostatically sensitive
components.
·Therefore, do not touch any contacts.
·Observe the handling specifications for electrostatically
sensitive components.
You avoid malfunctions of and damage to the electronics by
doing so.
Information about fitting the CPX terminal can be found in the
CPX system manual (P.BE−CPX−SYS−...).
