touch and solid impurities up to 12.5mm diameter, but not against water
penetration. Unless otherwise specified, the device must not be operated in
wet and dusty environments.
1.1.4 Technical Condition of the Devices
For each individual application, the components are supplied from the factory
with a dedicated hardware and software configuration. Changes in hardware,
software and firmware are only admitted within the framework of the
possibilities documented in the manuals. All changes to the hardware or
software and the non-conforming use of the components entail the exclusion
of liability on the part of WAGO Kontakttechnik GmbH & Co. KG.
Please direct any requirements pertaining to a modified and/or new hardware
or software configuration directly to WAGO Kontakttechnik GmbH & Co.
KG.
1.2 Standards and Regulations for Operating the 750 Series
Please observe the standards and regulations that are relevant to your
installation:
• The data and power lines must be connected and installed in compliance
with the standards to avoid failures on your installation and eliminate any
danger to personnel.
• For installation, startup, maintenance and repair, please observe the
accident prevention regulations of your machine (e.g. BGV A 3,
"Electrical Installations and Equipment").
• Emergency stop functions and equipment must not be made ineffective.
See relevant standards (e.g. DIN EN 418).
• Your installation must be equipped in accordance to the EMC guidelines
so that electromagnetic interferences can be eliminated.
• Operating 750 Series components in home applications without further
measures is only permitted if they meet the emission limits (emissions of
interference) according to EN 61000-6-3. You will find the relevant
information in the section on "WAGO-I/O-SYSTEM 750" Æ"System
Description" Æ"Technical Data".

• Please observe the safety measures against electrostatic discharge
according to DIN EN 61340-5-1/-3. When handling the modules, ensure
that the environment (persons, workplace and packing) is well grounded.
• The relevant valid and applicable standards and guidelines concerning the
installation of switch cabinets are to be observed.

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 fieldbus 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 The WAGO-I/O-SYSTEM 750
2.1 System Description
The WAGO-I/O-SYSTEM 750 is a modular, fieldbus independent I/O system.
It is comprised of a fieldbus coupler/controller (1) and connected fieldbus
modules (2) for any type of signal. Together, these make up the fieldbus node.
The end module (3) completes the node.
Fig. 2-1: Fieldbus node g0xxx00x
Couplers/controllers for fieldbus systems such as PROFIBUS, INTERBUS,
ETHERNET TCP/IP, CAN (CANopen, DeviceNet, CAL), MODBUS, LON
and others are available.
The coupler/controller contains the fieldbus interface, electronics and a power
supply terminal. The fieldbus interface forms the physical interface to the
relevant fieldbus. The electronics process the data of the bus modules and
make it available for the fieldbus communication. The 24 V system supply and
the 24 V field supply are fed in via the integrated power supply terminal.
The fieldbus coupler communicates via the relevant fieldbus. The
programmable fieldbus controller (PFC) enables the implementation of
additional PLC functions. Programming is done with the WAGO-I/O-PRO 32
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.

With a special permit, the system can also be implemented with other fieldbus
couplers/controllers in residential areas (housing, commercial and business areas, small-
scale enterprises). The special permit can be obtained from an authority or inspection
office. In Germany, the Federal Office for Post and Telecommunications and its branch
offices issues the permit.
It is possible to use other field bus couplers/controllers under certain boundary
conditions. Please contact WAGO Kontakttechnik GmbH & Co. KG.
Maximum power dissipation of the components
Bus modules 0.8 W / bus terminal (total power dissipation,
system/field)
Fieldbus coupler/controller 2.0 W / coupler/controller
Warning
The power dissipation of all installed components must not exceed the
maximum conductible power of the housing (cabinet).
When dimensioning the housing, care is to be taken that even under high
external temperatures, the temperature inside the housing does not exceed the
permissible ambient temperature of 55 °C.
