2 Safety
2.1 General safety information
Warning
Danger of injury through uncontrolled movements of connected devices. Make
sure that electrical and pneumatic equipment are in a de-energised and pressure
less status.
Before working on the pneumatics:
 Switch off the compressed air supply
 Exhaust the valve terminal
Before working on the electrical components, e.g. before installation or mainten
ance work:
 Switch power supply off
In this way, you avoid:
– sudden uncontrolled movements of loose tubing
– accidental and uncontrolled movements of the connected actuators
– undefined switching statuses of the electronics.
– functional damage.
Note
– Installation and commissioning must be carried out only by authorized quali
fied personnel.
– The components of the valve terminal include electrostatically sensitive ele
ments. The components could be damaged if you touch the contact surfaces
of the plug connectors or if you do not observe the handling specifications for
electrostatically sensitive devices.
 Do not exceed the specified limits in the technical data.
 Start up only a completely mounted and wired valve terminal in order to avoid
uncontrolled movements of detached tubing lines (whip effect) or impair
ments caused by unlocked pneumatic connections.
2.2 Use for intended purpose
The valve terminal has been designed exclusively for controlling pneumatic actuat
ors. It is intended for installation in machines or automation technology systems
and must be used exclusively as follows:
– in an industrial environment; outside of industrial environments, e.g. in commer
cial and mixed-residential areas, actions to suppress interference may have to
be taken.
– within the limits of the technical data,
– in the original status, without unauthorised modifications,
– in excellent technical status.
Use for intended purpose is described completely in the documentation. Every
other use is considered not intended.
2.3 Training of specialized personnel
The product may be commissioned only by an electrotechnically qualified person,
who is familiar with the following topics:
– installation and operation of control and automation systems
– applicable regulations for operating safety-engineering systems
– applicable regulations for accident prevention and occupational safety
– documentation for the product

5.2 Power supply
Note
 Only use PELV circuits in accordance with IEC/EN 60204-1 for the electrical
power supply (protective extra-low voltage, PELV).
 Observe also the general requirements for PELV power circuits in accordance
with IEC/EN 60204-1.
 Only use voltage sources which ensure reliable electrical isolation of the oper
ating voltage in accordance with IEC/EN 60204-1.
 Always connect both circuits for operating and load voltage supply.
Through the use of PELV circuits, protection against electric shock (protection
against direct and indirect contact) is ensured in accordance with IEC/EN 60204-1.
5.3 Connecting cable
Note
– Long electric connecting cables reduce the resistance to interference. Use
connecting cables with a length of max. 30 m.
 Use the connecting cables NEBC-C-S1WA9-F-... for the valve terminal from the
Festo accessories. In this way, you ensure that protection class IP69k is ful
filled.
5.4 I-Port/IO-Link interface
The valve terminal can be connected as follows via the connecting cable:
– to an external I-Port interface
– to an IO-Link master (èChap. 7.1)
– to a decentralised CTEU bus node
Depending on the configuration of your valve terminal, the I-Port/IO-Link interface
(èFig. 3) is on the valve side (front side) or the connection side (reverse side) of
the left end plate.

6 Addressing
Note
– Addresses may be shifted if the valve terminal is extended.
– If a monostable 5/2-way valve (requiring an address) is mounted on a valve
position that supports the actuation of 2 addresses, one address remains
unused.
6.1 Addressing rules:
– Address assignment is in ascending order without gaps, from left to right.
– Address assignment is independent of whether the manifold sub-base is
equipped with a valve or a cover plate.
– Depending on the integrated electronics module, a valve position, comprising a
manifold sub-base with electronics module, occupies the following number of
addresses:
Colour of the electronics module Number of occupied addresses/valve position
Grey 1
Black 2 – Less significant address for coils 14
– Higher-value address for coils 12
Fig. 4
– A supply plate does not occupy an address (blue electronics module).

devices might only satisfy a lower degree of protection, a smaller temperature range, etc.
2) The valve terminal is intended for use in an industrial environment. Measures for interference suppres
sion may need to be implemented in residential areas.
3) Use connecting cables with a length of maximum 30 m.
