Legal Bases
WAGO-I/O-SYSTEM 750
PROFINET IO
All responsible persons have to familiarize themselves with the underlying
legal standards to be applied. WAGO Kontakttechnik GmbH & Co. KG does
not assume any liability whatsoever resulting from improper handling and
damage incurred to both WAGO´s own and third-party products by
disregarding detailed information in this Manual.
1.1.3 Use of the 750 Series in Compliance with Underlying
Provisions
Couplers, controllers and I/O modules found in the modular WAGO-I/O-
SYSTEM 750 receive digital and analog signals from sensors and transmit
them to the actuators or higher-level control systems. Using programmable
controllers, the signals can also be (pre-)processed.
The components have been developed for use in an environment that meets
the IP20 protection class criteria. Protection against finger injury and solid
impurities up to 12.5 mm diameter is assured; protection against water damage
is not ensured. Unless otherwise specified, operation of the components in wet
and dusty environments is prohibited.
1.1.4 Technical Condition of Specified Devices
The components to be supplied Ex Works, are equipped with hardware and
software configurations, which meet the individual application requirements.
Changes in hardware, software and firmware are permitted exclusively within
the framework of the various alternatives that are documented in the specific
manuals. WAGO Kontakttechnik GmbH & Co. KG will be exempted from
any liability in case of changes in hardware or software as well as to non-
compliant usage of components.
Please send your request for modified and new hardware or software
configurations directly to WAGO Kontakttechnik GmbH & Co. KG.

Standards and Guidelines for Operating the 750 Series
WAGO-I/O-SYSTEM 750
PROFINET IO
1.2 Standards and Guidelines for Operating the 750 Series
Please adhere to the standards and guidelines required for the use of your
system:
• The data and power lines shall be connected and installed in compliance
with the standards required to avoid failures on your system and to
substantially minimize any imminently hazardous situations resulting in
personal injury.
• For assembly, start-up, maintenance and troubleshooting, adhere to the
specific accident prevention provisions which apply to your system (e.g.
BGV A 3, "Electrical Installations and Equipment").
• Emergency stop functions and equipment shall not be made ineffective.
See relevant standards (e.g. DIN EN 418).
• The equipment of your system shall be conform to EMC guidelines so that
any electromagnetic interferences will be eliminated.
• Operating 750 Series components in home applications without further
measures is permitted only if they meet the emission limits (emissions of
interference) in compliance with EN 61000-6-3. You will find the detailed
information in section "WAGO-I/O-SYSTEM 750" !"System
Description" !"Technical Data".
• Please observe the safety precautions against electrostatic discharge in
accordance with DIN EN 61340-5-1/-3. When handling the modules,
please ensure that environmental factors (persons, working place and
packaging) are well grounded.
• The valid standards and guidelines applicable for the installation of switch
cabinets shall be adhered to.

Safety Information
WAGO-I/O-SYSTEM 750
PROFINET IO
1.4 Safety Information
When connecting the device to your installation and during operation, the
following safety notes must be observed:
Danger
The WAGO-I/O-SYSTEM 750 and its components are an open system. It
must only be assembled in housings, cabinets or in electrical operation
rooms. Access is only permitted via a key or tool to authorized qualified
personnel.
Danger
All power sources to the device must always be switched off before carrying
out any installation, repair or maintenance work.
Warning
Replace defective or damaged device/module (e.g. in the event of deformed
contacts), as the functionality of field bus station in question can no longer be
ensured on a long-term basis.
Warning
The components are not resistant against materials having seeping and
insulating properties. Belonging to this group of materials is: e.g. aerosols,
silicones, triglycerides (found in some hand creams). If it cannot be ruled out
that these materials appear in the component environment, then the
components must be installed in an enclosure that is resistant against the
above mentioned materials. Clean tools and materials are generally required
to operate the device/module.
Warning
Soiled contacts must be cleaned using oil-free compressed air or with ethyl
alcohol and leather cloths.
Warning
Do not use contact sprays, which could possibly impair the functioning of the
contact area.
Warning
Avoid reverse polarity of data and power lines, as this may damage the
devices.
ESD (Electrostatic Discharge)
The devices are equipped with electronic components that may be destroyed
by electrostatic discharge when touched.

2.1 System Description
The WAGO-I/O-SYSTEM 750 is a modular, field bus independent I/O
system. It is comprised of a field bus coupler/controller (1) and connected
field bus modules (2) for any type of signal. Together, these make up the field
bus node. The end module (3) completes the node.
Fig. 2-1: Field bus node g0xxx00x
Couplers/controllers for field bus systems such as PROFIBUS, INTERBUS,
ETHERNET TCP/IP, CAN (CANopen, DeviceNet, CAL), MODBUS, LON
and others are available.
The coupler/controller contains the field bus interface, electronics and a power
supply terminal. The field bus interface forms the physical interface to the
relevant field bus. The electronics process the data of the bus modules and
make it available for the field bus communication. The 24 V system supply
and the 24 V field supply are fed in via the integrated power supply terminal.
The field bus coupler communicates via the relevant field bus. The
programmable field bus controller (PFC) enables the implementation of
additional PLC functions. Programming is done with the WAGO I/O PRO
CAA in accordance with IEC 61131-3.
Bus modules for diverse digital and analog I/O functions as well as special
functions can be connected to the coupler/controller. The communication
between the coupler/controller and the bus modules is carried out via an
internal bus.
The WAGO-I/O-SYSTEM 750 has a clear port level with LEDs for status
indication, insertable mini WSB markers and pullout group marker carriers.
The 3-wire technology supplemented by a ground wire connection allows for
direct sensor/actuator wiring.
